Code to demonstrate method overloading by extending another class.

package oops;

    class Superclass
    {
        public void m1()
        {
        System.out.println("no arg");
        }
    }

    public class OLSuperSub extends Superclass {
        public void m1(int i)
        {    
            System.out.println("one arg");
        }
        public static void main(String a[])
           {    
            OLSuperSub s=new OLSuperSub();
            s.m1();      // no arg
            s.m1(10);    // one arg
            
            }
}
