1. Study Chapter 3G

2. Sign up repl,it and study the example https://repl.it/join/aydclqoj-xtang

3. Design and implement your own GUI application

4. You can use other IDE such as eclips. Here is the code:

import javax.swing.JFrame;

import javax.swing.JPanel;

import java.awt.*;

/**

* Draws a snowman to demonstrate drawing methods and use of color.

* @author Java Foundations, converted to GUI by mvail

*/

public class Snowman extends JPanel

{

/**

* @param page object on which drawing takes place

*/

public void paintComponent (Graphics page)

  {

  final int MID = 150;

  final int TOP = 50;

  

  page.setColor(Color.CYAN);

  page.fillRect(0, 0, getWidth(), getHeight());

  

  Color groundColor = new Color(127, 0, 64);

  page.setColor (groundColor);

  page.fillRect (0, 175, 300, 50); // ground

  page.setColor (Color.yellow);

  page.fillOval (-40, -40, 80, 80); // sun

  page.setColor (Color.white);

  page.fillOval (MID - 20, TOP, 40, 40); // head

  page.fillOval (MID - 35, TOP + 35, 70, 50); // upper torso

  page.fillOval (MID - 50, TOP + 80, 100, 60); // lower torso

  page.setColor (Color.black);

  page.fillOval (MID - 10, TOP + 10, 5, 5); // left eye

  page.fillOval (MID + 5, TOP + 10, 5, 5); // right eye

  page.drawArc (MID - 10, TOP + 20, 20, 10, 190, 160); // smile

  page.drawLine (MID - 25, TOP + 60, MID - 50, TOP + 40); // left arm

  page.drawLine (MID + 25, TOP + 60, MID + 55, TOP + 60); // right arm

  page.drawLine (MID - 20, TOP + 5, MID + 20, TOP + 5); // brim of hat

  page.fillRect (MID - 15, TOP - 20, 30, 25); // top of hat

}

  

  /**

   * Constructor (panel initialization)

   */

  public Snowman()

  {

    setPreferredSize(new Dimension(300, 200));

  }
