6 Creating an Applet with a Background Color
In preparation for creating your own personal Web page, you would like to view
some possible background colors that will be easy to read with black text. You
decide to write a Java applet that displays black words on a colored background.
You will use the setBackground() method, which accepts a color argument in
applets.
1. Start TextPad. Save the file as Java source code with the file name
MyColorApplet.
2. Type a block header with the information about you and the assignment.
3. Import the java.awt.* and java.applet.* packages.
4. Write the class header for MyColorApplet. Remember to extend the Applet
class. Include an opening brace for the class.
5. Write a method header for the paint() method. Include an opening brace for
the method.
