* Ok, if you thought that the inherited '''move()''' method from the Rectangle class is not what we want to use, because the original Rectangle class does not know anything about the label, you are totally correct. If, furthermore, you thought you needed to create a new '''move()''' method for '''MyRect()''' that will ''override'' the Rectangle '''move()''' method, then I'm really impressed! | * Ok, if you thought that the inherited '''move()''' method from the Rectangle class is not what we want to use, because the original Rectangle class does not know anything about the label, you are totally correct.

* Create a new method called '''move()''' and base its design on the '''draw()''' method, so that it will call '''Rectangle.move()''' to make the yellow rectangle move, and it will activate the '''move()''' method of the label to make it move by the same dx, dy displacement. | * Create a new method called '''move()''' and base its design on the '''draw()''' method, so that it will call '''Rectangle.move()''' to make the yellow rectangle move, and it will activate the '''move()''' method of the label to make it move by the same dx, dy displacement. | ||
