2. C ONTENT What is Java ? Where is Java used ? Features of Java Java Program Translation Java Virtual Machine Java system overview Java Program-Development phase Advantage of java Disadvantage of java Project

3. WH A T IS J A V A ? Java is O bject O riented P rogramming language as well as Plateform. Java was developed by a team led by James Gosling at Sun Microsystems. Java is a first programming language which provide the concept of writing programs that can be executed using the web.

4. WHERE IS JAVA USED ? According to the Sun , 3 billion devices run java. There are many devices where Java is currently used. Desktop Applications - Acrobat reader, Media player, Antiviruses etc. Web Applications - irctc.co.in , javatpoint.com etc. Enterprise Application – Banking Application, Business Application. Mobile. Embedded System. Games. Robotics.

5. FEATURES OF JAVA Java is S imple. Java is O bject O riented Java is D istributed Java is A rchitecture N eutral Java is R obust Java is I nterpreted and C ompiled Java is S ecure Java is P ortable Java is M ulti-Threaded

6. JAVA PROGRAM TRANSLATION Hel l o. j av a j av ac Hello.class Interpreter for WinXP Interpreter for Mac Interpreter for Unix Source Program Java Compiler Java Bytecode

7. J A V A VI R T U AL M A CHINE Java virtual machine is the like usual computer which translate high level language into machine language. Just like that Java virtual machine also translate Bytecode into machine language. JVM are available for many hardware and software Plateform.

8. WHAT IS OOP ? Object-oriented programming is a method of implementation. A language in which everything represent in the form of Object is called Object Oriented Programming Language. It not only makes the program less complex but also makes the software reuse feasible and possible. Java is not truly Object Oriented Programing Language

11. JAVA PROGRAM-DEVELOPMENT PHASES

12. DATA TYPES IN JAVA

13. GARBAGE COLLECTION Garbage collection is the mechanism that De allocate the memory of an object when it is no longer referenced by a variable. In C++, the memory of an Object is released by use of delete operator. Java virtual machine determines when to free up the memory of an object.

14. ADVANTAGES OF JAVA Java is simple language. Java does not support POINTERS. Java is first language in which programs can be executed using web. W rite O nce R un A nywhere (WORA).

15. DISADVANTAGES OF JAVA Slow Performance. No support for Low level programming. Poor features in Java. No control over Garbage Collection.
