Chapter 3.8, Problem 27SC
Explanation of Solution
Drawings in java:
- When a user has to develop a drawing that contains multiple shapes, or parts that are made of multiple shapes, it is advised to create separate classes for each purpose or part.
- In the given scenario,
- The “Car” class contains the code that are used to draw a single car.
- The next class “CarComponent” is contains the code used to display the drawing.
- The last class “CarViewer” displays a frame that contains the “CarComponent”.
- Given program:
//import the required packages
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JComponent;
//define a class named CarComponent
public class CarComponent extends JComponent
{
//define a method named paintComponent
public void paintComponent(Graphics g)
{
//assign the value
Graphics2D g2 = (Graphics2D) g;

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels.
