Java Code Compilation and Interpretation

A programmer uses a Text Editor like Notepad and Textpad or IDE (Integrated Development Environment) to enter, edit and save the Program Source Code. The program source code file (program.java) is translated by the Java Compiler into a platform-independent format, known as Java Bytecodes (program.class). The Java Interpreter which is a part of the Java Virtual Machine (JVM) executes the Java Bytecodes. Unique JVMs are available for all major Operating Systems such as Windows, Solaris, Linux and Macintosh.
