App Development Using Java Swing, Collections, and IO Frameworks
We have learned various features from the Java API so far. It’s time for us try to use them in
developing some interesting applications. We have succeeded in Project 2 by creating a GUI that
can animate the moving and stopping of a curling rock. We will extend it into a team curling
game animation, with a window as shown below.
Application Context
The extended GUI included titled panels (TitledBorder) displaying teams (Collections) of
players with the rocks the players use. Players can be added by clicking on the headshot
placeholder and selecting an image file (FileChooser and MouseAdapter) , while rock
colors can be customized using a ColorChooser dialog box. In addition, a custom icon can be
used to replace the default Java icon.
Programming Exercises
We will look up the Java API online as we go, and get some sample code as needed from the
tutorials on Oracle website.
0. A Window with an Icon of Your Choice.
The setIconImage method.
1. A Default Icon with an Image of Your Design.
The Icon interface.
2. A Default Icon with an Image of Your Design.

4. Responding to Mouse Clicks: on Left or Right Buttons.
The mousePressed method of the MouseAdapter class.
5. Choose a Color from a Dialog Box.
The showDialog method of the ColorChooser class.
6. Choose a File and Set It on Player Panel.
The FileChooser class and the BufferedImage class.
