Steps to compile a java program

1. Create your .java source file

   • Name of the file should be same as class name (just a norm, works otherwise).

2. Compile your .java source file to generate a .class file

   	javac -d <destination of .class files> sourcefile.java

   • .class file will have same name as class.

   • javac here is java compiler.

3. Go to destination folder which contains .class file and run following command.

   	java filename

   • Actually filename will be filename.class but we write without .class

   • java here is application launcher

• Note that jvm looks for public static void main(String[] variable) and not the compiler.

• Hence, when you do not mention this main function and compile program, it does not give you compile-time error. But when you run it without main run-time error is obtained.
