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.

Listings

Preview

In this module, you will learn how to do a linear merge on two pictures based on the distance of each pixel from the left side of the picture.

Program specifications

Write a program named Prob05 that uses the class definition shown in Listing 1 and Ericson's media library along with the image files named Prob05a.jpg and Prob05b.jpg (see Figure 1 and Figure 2 ) to produce the graphic output image shown in Figure 3 .

Figure 1 - Input file named Prob05a.jpg.

Image of a penguin near the right side of the frame.

Figure 2 - Input file named Prob05b.jpg.

Image of a rabbit near the left side of the frame

Figure 3 - Required graphic output image.

Merged image showing a rabbit near the left side of the the frame and a penguin near the right side of the frame. Image also shows an elliptical sun in the center with a gradient from yellow to orange.

Required output text

In addition to the output image mentioned above, your program must display your name and the other line of text shown in Figure 4 on the command-line screen.

Figure 4 - Required output text.
Display your name here. Picture, filename None height 252 width 330

Discussion and sample code

This program does a linear merge on two pictures based on the distance of each pixel from the left side of the picture. The program also adds a sunwith a gradient and the student's name to the picture.

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 Prob05

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

Listing 1 - The driver class named Prob05.
public class Prob05{ public static void main(String[]args){ new Prob05Runner().run();}//end main method }//end class Prob05

The code in Listing 1 shouldn't require an explanation at this stage in the course.

Beginning of the class named Prob05Runner

The class named Prob05Runner begins in Listing 2 .

Listing 2 - Beginning of the class named Prob05Runner.
class Prob05Runner{ public Prob05Runner(){System.out.println("Display your name here."); }//end constructor
