Is that Overload or Override?

Question

public class overload1 {
    public Object show()
    {
        return "0";

    }

}
class overload2 extends overload1{
    public String show(){
        return "1";
    }
}

Answer 1

Override. You are extending the class, and overriding the superclass method.

Overload would look like this:

public class overload1 {
    public Object show()
    {
        return "0";
    }
    public Object show(Object arg)  // Same method name, but different arguments.
    {
        return "0";
    }
}
