Question

In the following example pseudocode:

public class MyPanel extends JPanel {
    public void reset() {
        this.clear();
        clear();
    }
    public void clear() { System.out.println("FAIL"); }
};

public class MySpecialPanel extends MyPanel {
    public void clear() { System.out.println("Hello, world"); }
};

When calling (new MySpecialPanel()).reset() shouldn’t both this.clear() and clear() resolve in the same scope? Is there any difference between this.clear() and clear()?

Answer 1

public void reset() {
    this.clear();
    clear();
}

In the code above, that calls the same method twice. There is no difference between clear() and this.clear().

You can explicitly call the superclasses method with super.clear().
