If a source code is written in C,then after compilation platform dependent native code is generated which is specific to the platform and whenever if you want to execute the same source code into different platform you have to recompile the program which is wastage of time.
srcprogram-->compile-->platform1---->platform native code
srcprogram-->compile-->platform2-->platform2 native code
But coming to Java,when you compile your source code ,an intermediate code is generated(.class file)which is common to all the platforms and you can execute the .class file on any platform with the help of jvm to generate native code of the specific platform.
src prg(.javafile)-->compile(on any platform Xplatform)-->bytecode(.classfile)-->jvm(execute on)-->platform(p1 or p2...or pn)(to get native code)
that is what java's passion compile once run anywhere
