Class NumberRange

  • All Implemented Interfaces:
    Range<Comparable>, Iterable<Comparable>, Collection<Comparable>, List<Comparable>
    public class NumberRange
extends AbstractList<Comparable>
implements Range<Comparable>
    Represents an immutable list of Numbers from a value to a value with a particular step size. In general, it isn't recommended using a NumberRange as a key to a map. The range 0..3 is deemed to be equal to 0.0..3.0 but they have different hashCode values, so storing a value using one of these ranges couldn't be retrieved using the other.
    Since:
    2.5.0

        public NumberRange​(T from,
                   U to)
        Creates an inclusive NumberRange with step size 1. Creates a reversed range if from < to.
        Parameters:
        from - the first value in the range
        to - the last value in the range

        public NumberRange​(T from,
                   U to,
                   boolean inclusive)
        Creates a new NumberRange with step size 1. Creates a reversed range if from < to.
        Parameters:
        from - start of the range
