How the bytecode makes portability in java?

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 special format called byte
code. Java byte code written in hexadecimal, byte by byte,
