This philosophy is called вЂњWrite Once, Run AnywhereвЂќ. But your program is guaranteed to run in any system thanks to this VM. This Virtual Machine is machine dependent, that is it has different implementations for Windows, Linux and Mac. This adds a huge bonus of security.ДЄlso, once your bytecode is compiled, it can run on any Java VM. This Virtual Machine exposes several APIs for low level machine interactions you can make, but other than that you cannot play with machine instructions explicitly. Instead, your program runs on a Virtual Machine called JVM. Java is a pretty secure language as it doesnвЂ™t let your program run directly on the machine. java files, and Java compiles them into bytecodes which are run on a Java Virtual Machine or JVM for execution. Java is an interpreted and compiled language, that is the code we write gets compiled to bytecode and interpreted to run. Ok now since we are done with the installations, letвЂ™s begin to understand first the nitty gritty of the Java ecosystem. If you still canвЂ™t figure it out, don't worry, just ask us in our Gitter room! JVM Also there are guides for Ubuntu and Mac as well.
