public class StringComparator
extends java.lang.Object
implements java.util.Comparator
Comparator
interface.
It is suitable for use on any objects for which the toString
method provides a suitable basis for object comparison.
You might think that calling java.text.Collator.getInstance
ought to provide much the same thing; however that gives you a
compare
method which casts to String
rather
than calling the toString
method on its arguments,
leading to a ClassCastException
in most useful cases.
I wonder why it does that?
