1.java solves the problem of platform-independence by using
byte code. The Java compiler does not produce native
executable code for a particular machine like a C compiler
would. Instead it produces a format called byte
code. Java byte code written in hexadecimal.
2.This format is same in every operatingf system like Solaris workstation,linux.After comilation the interpreter reads the
the byte code and translate according to the host machine.
3.Byte code is interprted in JVM.which avalibale in all operating systems.that we install.
