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 .
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.
In this module, you will learn how to mirror images, both horizontally and vertically.
Program specifications
Write a program named Prob02 that uses the class definition shown in Listing 1 and Ericson's media library along with the image file named Prob02a.jpg (shown in Figure 1 ) to produce the three graphic output images shown in Figure 2 , Figure 3 , and Figure 4 .
Figure 1 - Input file named Prob02a.jpg.
Figure 2 - First output image.
Figure 3 - Second output image.
Figure 4 - Third output image.
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 Prob02 shown in Listing 1 .
Rotate and mirror
The image from the file named Prob02a.jpg is rotated by 35 degrees. It is not scaled. Then the top-left quadrant of the picture containingthe rotated image is mirrored into the top-right quadrant. Following this, the top half of the picture is mirrored into the bottom half.
Required output text
In addition to the three output images mentioned above, your program must display your name and the other line of text shown in Figure 5 on the command-line screen
| Figure 5 - Required output text. |
|---|
Display your name here.
Picture, filename None height 404 width 425 |
Will discuss in fragments
I will discuss and explain this program in fragments. A complete listing of the program is provided in Listing 6 near the end of the module.
The driver class named Prob02
The driver class containing the main method is shown in Listing 1 .
| Listing 1 - The driver class named Prob02. |
|---|
public class Prob02{
public static void main(String[]args){
new Prob02Runner().run();}//end main method
}//end class Prob02 |
