Convert the ColoredPanes applet to appear within an application, that is, within a Frame instance, rather than an applet.

Skeleton Code

• ColorCanvas.java
• ColoredPanes.java

Tasks

1. Create class ColoredPanesAppl with nothing but a main() method that creates an instance of class ColoredPanesWindow, which you will create in the next task. Show that window.

2. Create class ColoredPanesWindow. Turn the applet init() into the constructor. Set the size to 100 x 100.

3. Add window-closing event handling to ColoredPanesWindow so you can close the window.

Where help exists, the task numbers above are linked to the step-by-step help page.

Solution Source

• ColoredPanesAppl.java

Demonstration

The program you are to write is an application and cannot be run from the browser. Run the solution from the command line as an application.
