Java files are converted to bit code format employing compiler then executed by the java interpreter. The whole java code is run on the java virtual machine which provides a runtime environment.
The most popular feature of java is that it’s platform-independent. Compilation happens in bytecode and because of this, java can run on any machine. It is a very secure language as it contains no virus. Java has the feature of multithreading. This feature helps java to do multi-tasking may be a portable language because it can run on any platform.
