Below is an applet that should show the current day in the locale you select. The locale selection is in a separate, pop-up window. The list of locales depends on your Java installation.
Note how the control reacts to the change of which day is first of week, depending on locale.
The source is the jar here. The jar contains both the source for the calender gui control, the applet using it, the locale dialog and unit test code.
The control is made of a stock Swing Table. See UML class diagram below. Further below you'll find UML diagram for the example applet and application.
