Preface

This module is one of a series of modules designed to teach you about Object-Oriented Programming (OOP) using Java.

The program described in this module requires the use of the Guzdial-Ericson multimedia class library. You will find download, installation, and usageinstructions for the library at Java OOP: The Guzdial-Ericson Multimedia Class Library .

Viewing tip

I recommend that you open another copy of this document in a separate browser window and use the following links to easily find and view the Figures and Listings while you are reading about them.

Figures

Listings

  • Listing 1 . The driver class named Prob04.
  • Listing 2 . Beginning of the class named Prob04Runner.
  • Listing 3 . Clip the picture and display your name.
  • Listing 4 . The method named clipToEllipse.
  • Listing 5 . Complete program listing.

Preview

In this module, you will learn how to use shapes to clip images during the drawing process.

Program specifications

Write a program named Prob04 that uses the class definition shown in Listing 1 and Ericson's media library along with the image file named Prob04a.jpg (see Figure 1 ) to produce the graphic output images shown in Figure 2 and Figure 3 . Don't forget to display your name in the output image as shown.

Figure 1 - Input file named Prob04a.jpg.

Figure 2 - First output image.

First output image

Figure 3 - Second output image.

Second output image shows the first output image clipped by an ellipse.

New classes

You may define new classes as necessary to cause your program to behave as required, but you may not modify the class definition for the class named Prob04 shown in Listing 1 .

Rotate, mirror, and clip

The program rotates a Picture object by 35 degrees with no scaling. Then it does a four-way mirror on the rotated picture. Finally, itclips the image to an elliptical format as shown in Figure 3 .

Required output text

In addition to the two output images shown above, your program must display your name and the other line of text shown in Figure 4 .

Figure 4 - Required text output.
Display your name here. Picture, filename None height 404 width 425

Discussion and sample code

Will discuss in fragments

I will discuss and explain this program in fragments. A complete listing of the program is provided in Listing 5 near the end of the module.

The driver class named Prob04

The driver class containing the main method is shown in Listing 1 .

Listing 1 - The driver class named Prob04.
public class Prob04{ public static void main(String[]args){ new Prob04Runner().run();}//end main method }//end class Prob04

If you have been studying the earlier modules in this collection, no explanation of Listing 1 should be required.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
