This example assumes that you are comfortable using the windows command prompt as well as how compiling and running basic java files.
First, use javac to compile the java class below.
public class Arg{
public static void main(String[] args){
System.out.println(args[0]);
}
}

First, let's recompile Hi.java so that it prints the second argument that is passed,ie args[1].
public static void main(String[] args){
System.out.println(args[1]);
