Hai all

plz any one share me what is Java Virtual Machine in java and why we called it virtual.

its just a name.
what it does is prepares the code to run on any platform.

It's the interpreter that translates the language into the machine language..

Each OS has it's own Java Virtual Machine (JVM).
When a Java application is compiled, it is transformed into intermediate code. This code will run on any JVM (vendor differences willing).
The JVM then makes the necessary system specific calls for the intermediate code. It's like a translator for applications on different operating systems.

Jvm compiles the byte codes into machine code..

Java is a most popular programing language.Java is a high level programing language devloped by sun microsystem.

Java virtual machine is called "virtual" because it is an abstract computer defined by a specification. To run this Java program, you need a concrete implementation of the abstract specification. This chapter describes primarily the abstract specification of the Java virtual machine. To illustrate the abstract definition of certain features, however, this chapter also discusses various ways in which those features could be implemented.
