JAVA APPLETS

JAVA APPLETS

August 2013. The Beginning Java course ended last month. And at this time, I fully understood what I was not understanding before the beginning of the course, specifically object's attributes and methods.

For our last assignment in class, we were to write a Java applet.  Writing applets turned out to be one of the best parts of Java programming.

Here is the graphics of the applet I turned in for my assignment:

Here are parts of the comments and code I turned in for this assignment.  The entire applet is written in one class with an inner class to implement the mouse listener.

// Begin class definition of applet.

// Extend JApplet class.

public class House extends JApplet

{

  // Declare global boolean variables.

  boolean openRightWindow, openDoor, openLeftWindow;

  // Applet method to set up the applet.

  public void init()

  {

    // Initialize global variables.

    openLeftWindow = true;

    openRightWindow = true;

    openDoor = true;

    // Build the content pane with white background.

    getContentPane().setBackground(Color.WHITE);

    // Add mouse event listener.

    addMouseListener(new MyMouseListener());

  }

  // Method that builds the contents of the content pane.

  public void paint(Graphics g)

  {

    // Invoke the superclass paint method.

    super.paint(g);

    // Set color to black.

    g.setColor(Color.BLACK);

//MORE CODES AND COMMENTS

Drawing graphics in the computer is so much fun and when you're writing their code, that's where the excitement steps in.

Happy drawing!
