You can use preference tools to configure almost every feature of the Java Desktop System. Each tool controls a particular part of the behavior of the Java Desktop System. For example, you can use a preference tool to select a theme for the Java Desktop System. A theme is a group of coordinated settings that specify the visual appearance of a part of your interface.
You can start your preference tools in either of the following ways:
Click Launch, then choose Preferences. Choose the item that you want from the submenus.
Double-click on the This Computer object on the desktop. A file browser window opens at the This Computer location. Double-click on the Preferences object to display the preference tools. Double-click on the item that you require.
