Classwork/Homework:
1. Write a program, YI_MovingCar.java that animates a car so that it moves across a frame.
2. Write a program, YI_TwoMovingCars.java that animates two cars moving across a frame in opposite directions (but at different heights so that they don’t collide.)

import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

   This program demonstrates how to install an action listener.
