calling parent class method using child class object

[Yash Don]

Hi,

In one of the interview it was asked to me that how will you call parent class version of method using child class object?
The exact Scenario is given below...

class Parent {
	public void m1() {
		System.out.println("PARENT");
	}
}

class Child extends Parent {
	public void m1() {
		System.out.println("CHILD");
	}
}

public class PolyTest {
	public static void main(String[] args) {

		Parent p = new Child();
		p.m1();
		//((Parent)p).m1(); ----> I tried this but of no use  
	}
}

Can you please tell me how can call Parent version of m1 method using an object of Child class...


Thanks,
Yash

You can't. Inside class Child you can call super.m1(), but what you want isn't possible.

here i have changed a little bit of code.....see it

	class Parent1 {   
	    public void m1() {   
	        System.out.println("PARENT");   
	    }   
	}  
	  
	class Child1 extends Parent1 {   
	    public void m1(String t) {   
	        System.out.println("CHILD");   
	    }   
	}   
	  
	public class PolyTest {   
	    public static void main(String[] args) {   
	  
	        Parent1 p = new Child1();   
	        p.m1();   
	        //((Parent1)p).m1(); ----> now this will work     
	    }   
	}

here object is of type child1,and refernce is of type parent1.
but this is the case of overloaded method...in this refernce type determines which method to invoke not a object type....

i think interviewer ask a tricky question

[Shanky Sohar]

but in case of overridden methods you cannot do that.
