Q) develop a java program that display the sum of two numbers supply the 2 numbers from the commandline?

A)

class add {

       public static void main(String[] args) {

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

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

              System.out.println("the sum :"+(a+b));

       }

}

Note:
            here ‘parseInt’ is a method. It belongs to the ‘Integer’ class. It is declared as static, that’s why     it is called by using class name.
