Explain the usual process for maintaining a chain of custody.
What will be an ideal response?
Write an application that mimics the behavior of a screen saver. It should draw random shapes onto a black background and the shapes should build up on top of each other until the screen saver resets (every 30 seconds). You have been provided with a Screen Saver application that does not yet display outlined shapes. It uses the MyRectangle and MyOval classes that you created in this tutorial. Add the code that will display random outlined shapes in your output. Your output should look like Fig. 27.34.
a) Copying the template to your working directory. Copy the C:Examples Tutorial27ExercisesAdvancedScreenSaver directory to your C:SimplyJava directory.
b) Opening the template file. Open the MyRectangle.java file in your text editor.
c) Adding an instance variable to the MyRectangle class. At line 7, add a comment indicating that the instance variable is a boolean and will indicate whether or not the rectangle is filled. At line 8, add a private instance variable named filled of type boolean.
d) Modifying the MyRectangle constructor. You will now modify the MyRectangle constructor so that it can accept an additional boolean argument. At line 12, add a boolean argument named fill to the end of the parameter list. At line 16, set the instance variable filled equal to the value of parameter fill and on the same line, add a comment indicating that filled will specify if the shape will be filled.
e) Modifying the draw method. At line 31, add a comment indicating that an if statem
