Class ClockDisplay12

java.lang.Object
  extended by ClockDisplay12

public class ClockDisplay12
extends java.lang.Object

The ClockDisplay class implements a digital clock display for a European-style 24 hour clock. The clock shows hours and minutes. The range of the clock is 00:00 (midnight) to 23:59 (one minute before midnight). The clock display receives "ticks" (via the timeTick method) every minute and reacts by incrementing the display. This is done in the usual clock fashion: the hour increments when the minutes roll over to zero.
