The Way Java Works   Source : Create a source document. Use an established protocol ( in this case, the Java language).  Compiler : Run your document through a source code compiler. The compiler checks for errors and won't let you compile until it's satisfied that everything will run correctly. Output : The compiler creates a new document, coded into java bytecode. Any device capable of running java will be able to interpret / translate this file into something it can run . The compiled bytecode is platform-independent. Virtual Machines : Your friends don't have a physical Java Machines, but they all have a Virtual Java machine (implemented in software) running inside their electronic gadgets. The virtual machine reads and runs the bytecode.
