Java Virtual Machine

[James Tharakan]

Java is a platform independent language.
But i cannot run my java program in a system which does not have Java Virtual Machine.
So how is it system independent??

If i have to install Java Virtual Machine in every system to run the program then i can do the same with regrads to other programming languages by installing their compiler.

Hope my question is not a stupid question .
Please do explain it to me .
Thank you.

Your Java Program is platform independent ,Not the JVM

you need JVM specific to your platform to run the java program...

java is an interpreted language. one thing JVM is not a platform independent. every Operating System needs its own JVM.

example if you compile a java file in windows,then you take the compiled file (.class) into unix,then if you run it will run...

but no idea about other language

As long as you follow a few simple rules eg use println rather than \n, the very same Java code and Java bytecode will run unchanged on machines with different operating systems, different CPUs, etc. But, as Pratap koritala has told you, you have to have different Java runtime environments (JREs) for different computers. (The JRE is included in the JDK you installed).
