Contrary to the general instructions given above, you may not define any new classes to cause your program to behave as required.

You must copy and modify (if necessary) the media classes named World.java, Turtle.java, and SimpleTurtle.java to cause your program to produce the required output. Don't forget to compile these classes after you modify them.

In addition to the output image, your program must produce the following output on the command- line screen, and must substitute your name for mine wherever my name appears both in the image and on the command-line screen:

/*File Prob03 Copyright 2012 R.G.Baldwin

Write a program named Prob03 that uses Ericson's media library to produce the graphic output images shown in Figure 3 and Figure 4 below.

Click here to download a zip file containing the source code for a solution.

The image shown in Figure 3 is the image that appears on the screen when the program starts running. The image shown in Figure 4 is what you should see when you click the button at the bottom of the world.

You must copy and modify (if necessary) the media class named World.java, to cause your program to produce the required output with the required behavior. Don't forget to compile that class after you modify it.

This program adds a JButton object to the SOUTH location of the World object as shown in Figure 3 .

The program initially displays an empty white world. When the user clicks the button, the world's background color changes to blue, a turtle appears in the center of the World, and the student's name appears near the top of the world.

/*File Prob04 Copyright 2012 R.G.Baldwin

Write a program named Prob04 that uses Ericson's media library to produce the graphic output images shown in Figure 5 , Figure 6 , and Figure 7 below.

Click here to download a zip file containing the source code for a solution.

Figure 5 shows the image that appears on the screen when the program starts running. Figure 6 shows what you should see after you have clicked the button at the bottom of the world one time. Figure 6 shows what you should see after you have clicked the button sixteen times.

You must copy and modify the media classes named World.java and SimplePicture.java, to cause your program to produce the required output with the required behavior. Don't forget to compile those classes after you modify them.

This program adds a JButton object to the SOUTH location of the World object as shown in Figure 5 .

The following description is intended to guide you in writing your program. However, you must run my version of the program and replicate it exactly. I recommend that you run the two programs side-by-side and compare their appearance and behavior each time you click both programs.

The program initially displays an empty white world with a button at the bottom. When the user clicks the button, the world's background color changes to green, a turtle appears in the bottom right of the World, and the student's name appears near the top of the world in blue. The turtle has a blue body and a red shell.

When you click the button again, the background changes to yellow, the student's name changes to red, and the turtle changes to a red body with a blue shell. The turtle turns 90 degrees left and moves forward 100 pixels plus the value of a click counter. As a result, the turtle leaves a blue trail.

On the next click, the colors revert to the same as before, the turtle turns 90 degrees left and moves forward 100 pixels plus the value of the click counter leaving a red trail.

This cycle repeats on each click with the turtle's trail drawing a square spiral of increasing size with red lines on the top and bottom of the spiral and blue lines on the right and left of the spiral.

/*File Prob05 Copyright 2012 R.G.Baldwin

Write a program named Prob05 that uses Ericson's media library to produce the graphic output image shown in Figure 8 , Figure 9 , and Figure 10 below.

Click here to download a zip file containing the source code for a solution.

Figure 8 shows the image that appears on the screen when the program starts running. Figure 9 shows what you should see after you have entered numeric values into the angle and distance fields and have clicked the Move button. Figure 10 is similar to what you should see after doing the above several times for different numeric values.

You must copy and modify the media class named World.java to cause your program to produce the required output with the required behavior. Don't forget to compile World.java after you modify it.

This program adds two buttons, two labels, and two text fields to form a GUI at the bottom of the World object.

If you enter numeric values into the angle and distance fields and then click the Move button, the turtle will turn by that angle in degrees and move by that distance in pixels.

The program must terminate and return control to the operating system when you click the Quit button.

Note that the GUI at the bottom of the World object is comprised of AWT components instead of Swing components.
