  View	Discussion	Improve	Article	Save	Article	Like	Article	As	the	name	suggests,	Object-Oriented	Programming	or	OOPs	refers	to	languages	that	use	objects	in	programming,	they	use	objects	as	a	primary	source	to	implement	what	is	to	happen	in	the	code.	Objects	are	seen	by	the	viewer	or	user,	performing	tasks	assigned	by	you.	Object-oriented
  programming	aims	to	implement	real-world	entities	like	inheritance,	hiding,	polymorphism	etc.	in	programming.	The	main	aim	of	OOP	is	to	bind	together	the	data	and	the	functions	that	operate	on	them	so	that	no	other	part	of	the	code	can	access	this	data	except	that	function.	Let	us	discuss	prerequisites	by	polishing	concepts	of	method	declaration
  and	message	passing.	Starting	off	with	the	method	declaration,	it	consists	of	six	components:	Access	Modifier:	Defines	the	access	type	of	the	method	i.e.	from	where	it	can	be	accessed	in	your	application.	In	Java,	there	are	4	types	of	access	specifiers:	public:	Accessible	in	all	classes	in	your	application.protected:	Accessible	within	the	package	in	which
  it	is	defined	and	in	its	subclass(es)	(including	subclasses	declared	outside	the	package).private:	Accessible	only	within	the	class	in	which	it	is	defined.default	(declared/defined	without	using	any	modifier):	Accessible	within	the	same	class	and	package	within	which	its	class	is	defined.The	return	type:	The	data	type	of	the	value	returned	by	the	method
  or	void	if	it	does	not	return	a	value.Method	Name:	The	rules	for	field	names	apply	to	method	names	as	well,	but	the	convention	is	a	little	different.Parameter	list:	Comma-separated	list	of	the	input	parameters	that	are	defined,	preceded	by	their	data	type,	within	the	enclosed	parentheses.	If	there	are	no	parameters,	you	must	use	empty	parentheses
  ().Exception	list:	The	exceptions	you	expect	the	method	to	throw.	You	can	specify	these	exception(s).Method	body:	It	is	the	block	of	code,	enclosed	between	braces,	that	you	need	to	execute	to	perform	your	intended	operations.Message	Passing:	Objects	communicate	with	one	another	by	sending	and	receiving	information	to	each	other.	A	message	for
  an	object	is	a	request	for	execution	of	a	procedure	and	therefore	will	invoke	a	function	in	the	receiving	object	that	generates	the	desired	results.	Message	passing	involves	specifying	the	name	of	the	object,	the	name	of	the	function	and	the	information	to	be	sent.Now	that	we	have	covered	the	basic	prerequisites,	we	will	move	on	to	the	4	pillars	of
  OOPs	which	are	as	follows.	But,	let	us	start	by	learning	about	the	different	characteristics	of	an	Object-Oriented	Programming	Language.OOPS	concepts	are	as	follows:	A	class	is	a	user-defined	blueprint	or	prototype	from	which	objects	are	created.	It	represents	the	set	of	properties	or	methods	that	are	common	to	all	objects	of	one	type.	Using	classes,
  you	can	create	multiple	objects	with	the	same	behavior	instead	of	writing	their	code	multiple	times.	This	includes	classes	for	objects	occurring	more	than	once	in	your	code.	In	general,	class	declarations	can	include	these	components	in	order:	Modifiers:	A	class	can	be	public	or	have	default	access	(Refer	to	this	for	details).Class	name:	The	class	name
  should	begin	with	the	initial	letter	capitalized	by	convention.Superclass	(if	any):	The	name	of	the	class’s	parent	(superclass),	if	any,	preceded	by	the	keyword	extends.	A	class	can	only	extend	(subclass)	one	parent.Interfaces	(if	any):	A	comma-separated	list	of	interfaces	implemented	by	the	class,	if	any,	preceded	by	the	keyword	implements.	A	class	can
  implement	more	than	one	interface.Body:	The	class	body	is	surrounded	by	braces,	{	}.An	object	is	a	basic	unit	of	Object-Oriented	Programming	that	represents	real-life	entities.	A	typical	Java	program	creates	many	objects,	which	as	you	know,	interact	by	invoking	methods.	The	objects	are	what	perform	your	code,	they	are	the	part	of	your	code	visible
  to	the	viewer/user.	An	object	mainly	consists	of:	State:	It	is	represented	by	the	attributes	of	an	object.	It	also	reflects	the	properties	of	an	object.Behavior:	It	is	represented	by	the	methods	of	an	object.	It	also	reflects	the	response	of	an	object	to	other	objects.Identity:	It	is	a	unique	name	given	to	an	object	that	enables	it	to	interact	with	other
  objects.Method:	A	method	is	a	collection	of	statements	that	perform	some	specific	task	and	return	the	result	to	the	caller.	A	method	can	perform	some	specific	task	without	returning	anything.	Methods	allow	us	to	reuse	the	code	without	retyping	it,	which	is	why	they	are	considered	time	savers.	In	Java,	every	method	must	be	part	of	some	class,	which
  is	different	from	languages	like	C,	C++,	and	Python.	Let	us	now	discuss	the	4	pillars	of	OOPs:Pillar	1:	AbstractionData	Abstraction	is	the	property	by	virtue	of	which	only	the	essential	details	are	displayed	to	the	user.	The	trivial	or	non-essential	units	are	not	displayed	to	the	user.	Ex:	A	car	is	viewed	as	a	car	rather	than	its	individual	components.Data
  Abstraction	may	also	be	defined	as	the	process	of	identifying	only	the	required	characteristics	of	an	object,	ignoring	the	irrelevant	details.	The	properties	and	behaviors	of	an	object	differentiate	it	from	other	objects	of	similar	type	and	also	help	in	classifying/grouping	the	object.Consider	a	real-life	example	of	a	man	driving	a	car.	The	man	only	knows
  that	pressing	the	accelerators	will	increase	the	car	speed	or	applying	brakes	will	stop	the	car,	but	he	does	not	know	how	on	pressing	the	accelerator,	the	speed	is	actually	increasing.	He	does	not	know	about	the	inner	mechanism	of	the	car	or	the	implementation	of	the	accelerators,	brakes	etc.	in	the	car.	This	is	what	abstraction	is.	In	Java,	abstraction
  is	achieved	by	interfaces	and	abstract	classes.	We	can	achieve	100%	abstraction	using	interfaces.Pillar	2:	EncapsulationIt	is	defined	as	the	wrapping	up	of	data	under	a	single	unit.	It	is	the	mechanism	that	binds	together	the	code	and	the	data	it	manipulates.	Another	way	to	think	about	encapsulation	is	that	it	is	a	protective	shield	that	prevents	the
  data	from	being	accessed	by	the	code	outside	this	shield.	Technically,	in	encapsulation,	the	variables	or	the	data	in	a	class	is	hidden	from	any	other	class	and	can	be	accessed	only	through	any	member	function	of	the	class	in	which	they	are	declared.In	encapsulation,	the	data	in	a	class	is	hidden	from	other	classes,	which	is	similar	to	what	data-hiding
  does.	So,	the	terms	“encapsulation”	and	“data-hiding”	are	used	interchangeably.Encapsulation	can	be	achieved	by	declaring	all	the	variables	in	a	class	as	private	and	writing	public	methods	in	the	class	to	set	and	get	the	values	of	the	variables.Pillar	3:	Inheritance	Inheritance	is	an	important	pillar	of	OOP	(Object	Oriented	Programming).	It	is	the
  mechanism	in	Java	by	which	one	class	is	allowed	to	inherit	the	features	(fields	and	methods)	of	another	class.	Let	us	discuss	some	frequently	used	important	terminologies:Superclass:	The	class	whose	features	are	inherited	is	known	as	superclass	(also	known	as	base	or	parent	class).Subclass:	The	class	that	inherits	the	other	class	is	known	as	subclass
  (also	known	as	derived	or	extended	or	child	class).	The	subclass	can	add	its	own	fields	and	methods	in	addition	to	the	superclass	fields	and	methods.Reusability:	Inheritance	supports	the	concept	of	“reusability”,	i.e.	when	we	want	to	create	a	new	class	and	there	is	already	a	class	that	includes	some	of	the	code	that	we	want,	we	can	derive	our	new
  class	from	the	existing	class.	By	doing	this,	we	are	reusing	the	fields	and	methods	of	the	existing	class.Pillar	4:	PolymorphismIt	refers	to	the	ability	of	object-oriented	programming	languages	to	differentiate	between	entities	with	the	same	name	efficiently.	This	is	done	by	Java	with	the	help	of	the	signature	and	declaration	of	these	entities.	Note:
  Polymorphism	in	Java	is	mainly	of	2	types:	Examplepublic	class	Sum	{				public	int	sum(int	x,	int	y)				{								return	(x	+	y);				}				public	int	sum(int	x,	int	y,	int	z)				{								return	(x	+	y	+	z);				}				public	double	sum(double	x,	double	y)				{								return	(x	+	y);				}				public	static	void	main(String	args[])				{								Sum	s	=	new
  Sum();								System.out.println(s.sum(10,	20));								System.out.println(s.sum(10,	20,	30));								System.out.println(s.sum(10.5,	20.5));				}}	Great	Learning	is	an	ed-tech	company	that	offers	impactful	and	industry-relevant	programs	in	high-growth	areas.

Know	More	Copy	Link!Object	Oriented	programming	is	a	programming	style	which	is	associated	with	the	concepts	like	class,	object,	Inheritance,	Encapsulation,	Abstraction,	Polymorphism.	Most	popular	programming	languages	like	Java,	C++,	C#,	Ruby,	etc.	follow	an	object-oriented
  programming	paradigm.	What	is	Object-Oriented	Programming?	Object-Oriented	programming	(OOP)	refers	to	a	type	of	programming	in	which	programmers	define	the	data	type	of	a	data	structure	and	the	type	of	operations	that	can	be	applied	to	the	data	structure.As	Java	being	the	most	sought-after	skill,	we	will	talk	about	object-oriented
  programming	concepts	in	Java.	An	object-based	application	in	Java	is	based	on	declaring	classes,	creating	objects	from	them	and	interacting	between	these	objects.	I	have	discussed	Java	Classes	and	Objects	which	is	also	a	part	of	object-oriented	programming	concepts,	in	my	previous	blog.Edureka	2019	Tech	Career	Guide	is	out!	Hottest	job	roles,
  precise	learning	paths,	industry	outlook	&	more	in	the	guide.	Download	now.The	building	blocks	of	object-oriented	programming	are	Inheritance,	Encapsulation,	Abstraction,	and	Polymorphism.	Let’s	understand	more	about	each	of	them	in	the	following	sequence:	Inheritance	Encapsulation	Abstraction	PolymorphismWhat	are	the	benefits	of	Object
  Oriented	Programming?	Improved	productivity	during	software	development		Improved	software	maintainability	Faster	development	sprints	Lower	cost	of	development	Higher	quality	softwareHowever,	there	are	a	few	challenges	associated	with	OOP,	namely:	Steep	learning	curve	Larger	program	size	Slower	program	execution	Its	not	a	one-size	fits
  all	solutionLet’s	get	started	with	the	first	Object	Oriented	Programming	concept,	i.e.	Inheritance.	Object	Oriented	Programming	:	InheritanceIn	OOP,	computer	programs	are	designed	in	such	a	way	where	everything	is	an	object	that	interact	with	one	another.	Inheritance	is	one	such	concept	where	the	properties	of	one	class	can	be	inherited	by	the
  other.	It	helps	to	reuse	the	code	and	establish	a	relationship	between	different	classes.	As	we	can	see	in	the	image,	a	child	inherits	the	properties	from	his	father.	Similarly,	in	Java,	there	are	two	classes:1.	Parent	class	(	Super	or	Base	class)2.	Child	class	(Subclass	or	Derived	class	)A	class	which	inherits	the	properties	is	known	as	Child	Class	whereas	a
  class	whose	properties	are	inherited	is	known	as	Parent	class.		Inheritance	is	further	classified	into	4	types:So	let’s	begin	with	the	first	type	of	inheritance	i.e.	Single	Inheritance:In	single	inheritance,	one	class	inherits	the	properties	of	another.	It	enables	a	derived	class	to	inherit	the	properties	and	behavior	from	a	single	parent	class.	This	will	in	turn
  enable	code	reusability	as	well	as	add	new	features	to	the	existing	code.Here,	Class	A	is	your	parent	class	and	Class	B	is	your	child	class	which	inherits	the	properties	and	behavior	of	the	parent	class.Let’s	see	the	syntax	for	single	inheritance:	Class	A	{	---	}	Class	B	extends	A	{	---	}	2.	Multilevel	Inheritance:When	a	class	is	derived	from	a	class	which	is
  also	derived	from	another	class,	i.e.	a	class	having	more	than	one	parent	class	but	at	different	levels,	such	type	of	inheritance	is	called	Multilevel	Inheritance.If	we	talk	about	the	flowchart,	class	B	inherits	the	properties	and	behavior	of	class	A	and	class	C	inherits	the	properties	of	class	B.	Here	A	is	the	parent	class	for	B	and	class	B	is	the	parent	class
  for	C.	So	in	this	case	class	C	implicitly	inherits	the	properties	and	methods	of	class	A	along	with	Class	B.	That’s	what	is	multilevel	inheritance.Let’s	see	the	syntax	for	multilevel	inheritance	in	Java:Class	A{	---	}	Class	B	extends	A{	---	}	Class	C	extends	B{	---	}	3.	Hierarchical	Inheritance:When	a	class	has	more	than	one	child	classes	(sub	classes)	or	in
  other	words,	more	than	one	child	classes	have	the	same	parent	class,	then	such	kind	of	inheritance	is	known	as	hierarchical.If	we	talk	about	the	flowchart,	Class	B	and	C	are	the	child	classes	which	are	inheriting	from	the	parent	class	i.e	Class	A.Let’s	see	the	syntax	for	hierarchical	inheritance	in	Java:Class	A{	---	}	Class	B	extends	A{	---	}	Class	C
  extends	A{	---	}Hybrid	inheritance	is	a	combination	of	multiple	inheritance	and	multilevel	inheritance.	Since	multiple	inheritance	is	not	supported	in	Java	as	it	leads	to	ambiguity,	so	this	type	of	inheritance	can	only	be	achieved	through	the	use	of	the	interfaces.	If	we	talk	about	the	flowchart,	class	A	is	a	parent	class	for	class	B	and	C,	whereas	Class	B
  and	C	are	the	parent	class	of	D	which	is	the	only	child	class	of	B	and	C.Now	we	have	learned	about	inheritance	and	their	different	types.	Let’s	switch	to	another	object	oriented	programming	concept	i.e	Encapsulation.Object	Oriented	Programming	:	EncapsulationEncapsulation	is	a	mechanism	where	you	bind	your	data	and	code	together	as	a	single
  unit.	It	also	means	to	hide	your	data	in	order	to	make	it	safe	from	any	modification.	What	does	this	mean?	The	best	way	to	understand	encapsulation	is	to	look	at	the	example	of	a	medical	capsule,	where	the	drug	is	always	safe	inside	the	capsule.	Similarly,	through	encapsulation	the	methods	and	variables	of	a	class	are	well	hidden	and	safe.We	can
  achieve	encapsulation	in	Java	by:	Declaring	the	variables	of	a	class	as	private.	Providing	public	setter	and	getter	methods	to	modify	and	view	the	variables	values.Let	us	look	at	the	code	below	to	get	a	better	understanding	of	encapsulation:	public	class	Employee	{	private	String	name;	public	String	getName()	{	return	name;	}	public	void
  setName(String	name)	{	this.name	=	name;	}	public	static	void	main(String[]	args)	{	}	}	Let	us	try	to	understand	the	above	code.	I	have	created	a	class	Employee	which	has	a	private	variable	name.	We	have	then	created	a	getter	and	setter	methods	through	which	we	can	get	and	set	the	name	of	an	employee.	Through	these	methods,	any	class	which
  wishes	to	access	the	name	variable	has	to	do	it	using	these	getter	and	setter	methods.Let’s	move	forward	to	our	third	Object-oriented	programming	concept	i.e.	Abstraction.Object	Oriented	Programming	:	AbstractionAbstraction	refers	to	the	quality	of	dealing	with	ideas	rather	than	events.	It	basically	deals	with	hiding	the	details	and	showing	the
  essential	things	to	the	user.	If	you	look	at	the	image	here,	whenever	we	get	a	call,	we	get	an	option	to	either	pick	it	up	or	just	reject	it.	But	in	reality,	there	is	a	lot	of	code	that	runs	in	the	background.	So	you	don’t	know	the	internal	processing	of	how	a	call	is	generated,	that’s	the	beauty	of	abstraction.	Therefore,	abstraction	helps	to	reduce
  complexity.	You	can	achieve	abstraction	in	two	ways:a)	Abstract	Classb)	InterfaceLet’s	understand	these	concepts	in	more	detail.Abstract	class:	Abstract	class	in	Java	contains	the	‘abstract’	keyword.	Now	what	does	the	abstract	keyword	mean?	If	a	class	is	declared	abstract,	it	cannot	be	instantiated,	which	means	you	cannot	create	an	object	of	an
  abstract	class.	Also,	an	abstract	class	can	contain	abstract	as	well	as	concrete	methods.	Note:	You	can	achieve	0-100%	abstraction	using	abstract	class.To	use	an	abstract	class,	you	have	to	inherit	it	from	another	class	where	you	have	to	provide	implementations	for	the	abstract	methods	there	itself,	else	it	will	also	become	an	abstract	class.Let’s	look
  at	the	syntax	of	an	abstract	class:	Abstract	class	Mobile	{	//	abstract	class	mobile	Abstract	void	run();	//	abstract	method	Interface:	Interface	in	Java	is	a	blueprint	of	a	class	or	you	can	say	it	is	a	collection	of	abstract	methods	and	static	constants.	In	an	interface,	each	method	is	public	and	abstract	but	it	does	not	contain	any	constructor.	Along	with
  abstraction,	interface	also	helps	to	achieve	multiple	inheritance	in	Java.	Note:	You	can	achieve	100%	abstraction	using	interfaces.	So	an	interface	basically	is	a	group	of	related	methods	with	empty	bodies.	Let	us	understand	interfaces	better	by	taking	an	example	of	a	‘ParentCar’	interface	with	its	related	methods.	public	interface	ParentCar	{	public
  void	changeGear(	int	newValue);	public	void	speedUp(int	increment);	public	void	applyBrakes(int	decrement);	}	These	methods	need	be	present	for	every	car,	right?	But	their	working	is	going	to	be	different.Let’s	say	you	are	working	with	manual	car,	there	you	have	to	increment	the	gear	one	by	one,	but	if	you	are	working	with	an	automatic	car,	that
  time	your	system	decides	how	to	change	gear	with	respect	to	speed.	Therefore,	not	all	my	subclasses	have	the	same	logic	written	for	change	gear.	The	same	case	is	for	speedup,	now	let’s	say	when	you	press	an	accelerator,	it	speeds	up	at	the	rate	of	10kms	or	15kms.	But	suppose,	someone	else	is	driving	a	super	car,	where	it	increment	by	30kms	or
  50kms.	Again	the	logic	varies.	Similarly	for	applybrakes,	where	one	person	may	have	powerful	brakes,	other	may	not.Since	all	the	functionalities	are	common	with	all	my	subclasses,	I	have	created	an	interface	‘ParentCar’	where	all	the	functions	are	present.	After	that,	I	will	create	a	child	class	which	implements	this	interface,	where	the	definition	to
  all	these	method	varies.Next,	let’s	look	into	the	functionality	as	to	how	you	can	implement	this	interface.	So	to	implement	this	interface,	the	name	of	your	class	would	change	to	any	particular	brand		of	a	Car,	let’s	say	I’ll	take	an	“Audi”.	To	implement	the	class	interface,	I	will	use	the	‘implement’	keyword	as	seen	below:	public	class	Audi	implements
  ParentCar	{	int	speed=0;	int	gear=1;	public	void	changeGear(	int	value){	gear=value;	}	public	void	speedUp(	int	increment)	{	speed=speed+increment;	}	public	void	applyBrakes(int	decrement)	{	speed=speed-decrement;	}	void	printStates(){	System.out.println("speed:"+speed+"gear:"+gear);	}	public	static	void	main(String[]	args)	{	//	TODO	Auto-
  generated	method	stub	Audi	A6=	new	Audi();	A6.speedUp(50);	A6.printStates();	A6.changeGear(4);	A6.SpeedUp(100);	A6.printStates();	}	}	Here	as	you	can	see,	I	have	provided	functionalities	to	the	different	methods	I	have	declared	in	my	interface	class.	Implementing	an	interface	allows	a	class	to	become	more	formal	about	the	behavior	it	promises
  to	provide.	You	can	create	another	class	as	well,	say	for	example	BMW	class	which	can	inherit	the	same	interface	‘car’	with	different	functionalities.	So	I	hope	you	guys	are	clear	with	the	interface	and	how	you	can	achieve	abstraction	using	it.Finally,	the	last	Object	oriented	programming	concept	is	Polymorphism.Object	Oriented	Programming	:
  PolymorphismPolymorphism	means	taking	many	forms,	where	‘poly’	means	many	and	‘morph’	means	forms.	It	is	the	ability	of	a	variable,	function	or	object	to	take	on	multiple	forms.	In	other	words,	polymorphism	allows	you	define	one	interface	or	method	and	have	multiple	implementations.	Let’s	understand	this	by	taking	a	real-life	example	and	how
  this	concept	fits	into	Object	oriented	programming.Let’s	consider	this	real	world	scenario	in	cricket,	we	know	that	there	are	different	types	of	bowlers	i.e.	Fast	bowlers,	Medium	pace	bowlers	and	spinners.	As	you	can	see	in	the	above	figure,	there	is	a	parent	class-	BowlerClass	and	it	has	three	child	classes:	FastPacer,	MediumPacer	and	Spinner.
  Bowler	class	has	bowlingMethod()	where	all	the	child	classes	are	inheriting	this	method.	As	we	all	know	that	a	fast	bowler	will	going	to	bowl	differently	as	compared	to	medium	pacer	and	spinner	in	terms	of	bowling	speed,	long	run	up	and	way	of	bowling,	etc.	Similarly	a	medium	pacer’s	implementation	of	bowlingMethod()	is	also	going	to	be	different
  as	compared	to	other	bowlers.	And	same	happens	with	spinner	class.	The	point	of	above	discussion	is	simply	that	a	same	name	tends	to	multiple	forms.	All	the	three	classes	above	inherited	the	bowlingMethod()	but	their	implementation	is	totally	different	from	one	another.Polymorphism	in	Java	is	of	two	types:		Run	time	polymorphism	Compile	time
  polymorphismRun	time	polymorphism:	In	Java,	runtime	polymorphism	refers	to	a	process	in	which	a	call	to	an	overridden	method	is	resolved	at	runtime	rather	than	at	compile-time.	In	this,	a	reference	variable	is	used	to	call	an	overridden	method	of	a	superclass	at	run	time.	Method	overriding	is	an	example	of	run	time	polymorphism.	Let	us	look		the
  following	code	to	understand	how	the	method	overriding	works:	public	Class	BowlerClass{	void	bowlingMethod()	{	System.out.println("	bowler	");	}	public	Class	FastPacer{	void	bowlingMethod()	{	System.out.println("	fast	bowler	");	}	Public	static	void	main(String[]	args)	{	FastPacer	obj=	new	FastPacer();	obj.bowlingMethod();	}	}	Compile	time
  polymorphism:	In	Java,	compile	time	polymorphism	refers	to	a	process	in	which	a	call	to	an	overloaded	method	is	resolved	at	compile	time	rather	than	at	run	time.	Method	overloading	is	an	example	of	compile	time	polymorphism.	Method	Overloading	is	a	feature	that	allows	a	class	to	have	two	or	more	methods	having	the	same	name	but	the
  arguments	passed	to	the	methods	are	different.	Unlike	method	overriding,	arguments	can	differ	in:	Number	of	parameters	passed	to	a	method	Datatype	of	parameters	Sequence	of	datatypes	when	passed	to	a	method.Let	us	look	at	the	following	code	to	understand	how	the	method	overloading	works:	class	Adder	{	Static	int	add(int	a,	int	b)	{	return
  a+b;	}	static	double	add(	double	a,	double	b)	{	return	a+b;	}	public	static	void	main(String	args[])	{	System.out.println(Adder.add(11,11));	System.out.println(Adder.add(12.3,12.6));	}	}I	hope	you	guys	are	clear	with	all	the	object	oriented	programming	concepts	that	we	have	discussed	above	i.e	inheritance,	encapsulation,	abstraction	and
  polymorphism.	Now	you	can	make	your	Java	application	more	secure,	simple	and	re-usable	using	Java	OOPs	concepts.	Do	read	my	next	blog	on	Java	String	where	I	will	be	explaining	all	about	Strings	and	its	various	methods	and	interfaces.Now	that	you	have	understood	the	Object	Oriented	Programming	concepts	in	Java,	check	out	the	Java	training	by
  Edureka,	a	trusted	online	learning	company	with	a	network	of	more	than	250,000	satisfied	learners	spread	across	the	globe.	Edureka’s	Java	J2EE	and	SOA	training	and	certification	course	is	designed	for	students	and	professionals	who	want	to	be	a	Java	Developer.	The	course	is	designed	to	give	you	a	head	start	into	Java	programming	and	train	you
  for	both	core	and	advanced	Java	concepts	along	with	various	Java	frameworks	like	Hibernate	&	Spring.Got	a	question	for	us?	Please	mention	it	in	the	comments	section	of	this	“Object	Oriented	Programming”	blog		and	we	will	get	back	to	you	as	soon	as	possible.
