1.we should set up a controller in order to do that.
2.If an action listener has been added to a button. The actionlister will interface and packages the code to move the object in an actionPerformed method.
3.The roles and responsibilities of the model of a control class is to obtain a input, convert , reset , and then output the result.

1. you can set up a timer by setting up the initial position of the shape
and at regular intervals move the object and repaint the panel.
2.the factor that affect the movement of a graphical object is position, velocity, direction. and turn.
3.Flicker is caused by the speed display medium when painting large complex images that must appear to move rapidly.We could elimiate flicker by simple display of constant motion in two dimensions.
4. A moving object has a velocity, which is the distance traveled in a given unit of time, and a direction.
