public static final class ArraysMDE.IntArrayComparatorLexical
extends java.lang.Object
implements java.util.Comparator<int[]>, java.io.Serializable
Note: this comparator imposes orderings that are inconsistent with Object.equals(java.lang.Object)
.
That is, it may return 0 if the arrays contain identical numbers but are not equal according to
equals()
(which tests reference equality).
