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.

Preview

In this module, you will learn how to darken, brighten, and tint the colors in a Picture object.

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 files in the following list to produce the four graphic output imagesshown in Figure 1 through Figure 4 .

  • Prob04a.bmp
  • Prob04b.bmp
  • Prob04c.jpg

Figure 1 - Input file Prob04a.bmp.

Image of a female ice skater on a green background.

Figure 2 - Input file Prob04b.bmp.

Image of a black ellipse on a green background.

Figure 3 - Input file Prob04c.jpg.

Image of a frozen lake with some houses on the far side.

Figure 4 - Required output image.

Image of the ice skater standing on the lake with a pink spotlight shining on her.

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 .

Required text output

In addition to the four 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.

Display your name here. Picture, filename None height 293 width 392

General background information

This program uses a black ellipse on a green background (see Figure 2 ) as a pattern to cause the pixels in a snow scene (see Figure 3 ) at the location of the ellipse to be given a red tint and causes all other pixels inthe snow scene to be darkened (see Figure 4 ) .

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
