Function Overriding

[harmeet saini]

Hi

Following is a code from CertPal, i am not able to understand why the following code gives me a compile time error

class Stain {public void stake(){System.out.println("argh ");}}
class Brain extends Stain {public void stake(){ System.out.println("grey ");}}

public class Cert extends Brain
{
    public static void main(String[] args)
    {
        Brain brain = new Cert(); brain.stake();
        Stain wizard = new Cert(); wizard.stake();
        Brain pain = new Stain(); pain.stake();
    }

    public void stake()
    {System.out.print("Tokyo ");}
}

Why don't you get the Error with the help of the Compilation Error? What about your 10th line? Is it legal? Check it.

[Prasad Kharkar]

we cannot refer to object of super type using subclass type reference
that is why the compiler complains

[Shanky Sohar]

Brain pain = new Stain(); pain.stake();

as brain extends stain(); //////so brain ISA stain;

this line gives error as the supertype object cannot be refer from a subtype reference......
