Java Compiler

I am a computing student and in this course we have got total four modules in our first semester(i.e Logic, Introduction to Programming, Problem Solving IT and Study Skills for Computing. Among them, I am writing here about java which is known as object oriented-programming.
Java is a programming language which was developed by Gosling at Sun-Microsystems in 1995. Java is not a procedural language but it is an extension. Java uses a java source code that is needed to be compiled to Java byte code to run in any JVM(Java Virtual Machine).

TYPES OF COMPILER:
1.Javac Compiler
2.Jikes Compiler
3.ESPRESSO Compiler
4.GNU Compiler

Originally, Javac Compiler was the one and only compiler which compiles java source code to java bytecode.  Similarly, Jikes, ESPRESSO and GNU compiles from java to java byte code. So, compilers are necessary for java to understand the programmer language by converting it to java bytecode which helps to carry out any program.
