//example of the overriding method
//return type and signature(parameter) same means the overriding method

class a1

        // where c1() is called instance


        //c1 obj1=new c1();

        // now we take the reference of b1 and instance c1 as same

       // b1 obj1=new c1();
      //  obj1.hell();

        //it's means that if we change the instance than automatically
        //sentence will be changed or method /function will be change

        //reference is a1 and instance c1
        //output is of c1 method is display

       // a1 obj1=new c1();
        //obj1.hell();

        //reference is a1 and instance b1
        //output is of b1 method is display
