java.lang.ObjectNumberDisplay
public class NumberDisplay
The NumberDisplay class represents a digital number display that can hold values from zero to a given limit. The limit can be specified when creating the display. The values range from zero (inclusive) to limit-1. If used, for example, for the seconds on a digital clock, the limit would be 60, resulting in display values from 0 to 59. When incremented, the display automatically rolls over to zero when reaching the limit.
