Java command line argument

Write a program in Java to demonstrate command line arguments.

class Cmd {
    public static void main(String[] args) {
        int a, b, sum;

        a = Integer.parseInt(args[0]);
        b = Integer.parseInt(args[1]);

        sum = a + b;

        System.out.println("Addition is: "+sum);
    }
}

Output

C:\PROGRA~1\Java\jdk1.6.0\bin>javac Cmd.java
C:\PROGRA~1\Java\jdk1.6.0\bin>java Cmd 10 20
