Java environment and deploy it to your hosts. Each host OS (Windows versus Linux versus
Mac OS for instance) has a different Java VM. When you package your Java program, your
source code is compiled to bytecode for the Java VM, and the VM converts it to machine code
to run on the hardware platform.
