3. WHATISJAVA?
Javais Object Oriented Programming language as
well asPlateform.
Java wasdeveloped by ateam led by JamesGosling
at SunMicrosystems.
Javais afirst programming language which provide
the concept of writing programs that can be
executed using the web.

4. WHEREISJAVAUSED?
According to the Sun, 3 billion devices run java.
There are many devices where Javais currently used.
DesktopApplications - Acrobat reader, Media player,
Antiviruses etc.
WebApplications - irctc.co.in , javatpoint.com etc.
EnterpriseApplication– BankingApplication, Business
Application.
Mobile.
Embedded System.
Games.
Robotics.

5. FEATURESOFJAVA

7. JAVAVIRTUAL MACHINE
Javavirtual machine is the like usual computer
which translate high level language into machine
language.
Justlike that Javavirtual machine alsotranslate
Bytecode into machinelanguage.
JVMare available for many hardware andsoftware
Plateform.

8. WHAT IS OOP?
Object-oriented programming is amethod of
implementation.
Alanguage in which everything represent inthe
form of Object is called Object Oriented
Programming Language.
It not only makesthe program lesscomplex but
also makesthe software reuse feasible andpossible.
Javais not truly Object OrientedPrograming
Language

9. CONCEPTS OF OOP
• Object
• Class
• Encapsulation
• Inheritance
• Polymorphism
• Abstraction

13. GARBAGECOLLECTION
Garbage collection is the mechanism that Deallocate
the memory of an object when itis no longer referenced
by avariable.
In C++,the memory of an Object is released by useof
delete operator.
Javavirtual machine determines when to free upthe
memory of anobject.

14. ADVANTAGESOFJAVA
Javais simple language.
Javadoes not support POINTERS.
Javais first language in which programs canbe
executed using web.
Write Once RunAnywhere (WORA).

15. DISADVANTAGESOFJAVA
 Slow Performance.
 No support for Low levelprogramming.
 Poor features in Java.
 No control over Garbage Collection.
