All Implemented Interfaces:

java.lang.Comparable<Range>

public class Range
extends java.lang.Object
implements java.lang.Comparable<Range>

This class stores the start and end integer values of a range of integers. It also provides methods to specify if a given integer value falls within the start and end range of integers stored in this class.
