Create a new NetBeans project named Homework12 as a general Java application with the usual freebie Main class. In the same package, also define
- A subclass of javax.swing.JFrame named DisplayFrame, which uses a BorderLayout layout manager.
-
A subclass of javax.swing.JPanel named DisplayPanel.
Override the inherited paintComponent() method of this
class so that it displays a centered "bullseye" pattern of
concentric red and white circles, as in the figure below:
Customize the DisplayFrame constructor so that it creates an instance of a DisplayPanel and adds it to the center of its own content pane. Finally, use the main() method of your freebie Main class to create and show a DisplayFrame in the middle of the screen.
