Java Program Development Compilation and Execution Procedure

• In java programming language all source code is first written in plain text file ending with the java extension.
• Those source files are then compiled into class files by the java compiler.
• A class file doesn't contain code that is native to the processor.
• It instead contains byte codes the native language of the java virtual machine(JVM).
•  The java launcher tool then runs your application with an instance of the java virtual machine

Below Commands we must use for compilation and execution 

• javac abc.java (java file)

                  abc.class

• java abc

                   output.
