Comparator<T>

public class NaturalComparator<T>
extends Object
implements Comparator<T>

This class defines a comparator that compares two objects of the same type using their natural compareTo method if the type implements the Comparable interface, or by doing a lexical comparison on their string formats if not. This comparator handles null values as well. A null value is always less than an non null value and two null values are equal.
