Defining the abstract class and implementing the sorting algorithm was

actually unnecessary.

The Java package java.util provides a class, Arrays, which defines and

implements many useful operations on arrays including

sorting and searching. Please look at the material on Arrays at

http://java.sun.com/products/jdk/1.2/docs/api/java/util/

Arrays.html#sort(java.lang.Object[])

Take a look at the several methods defined in Arrays including the method

public void sort(Object[] O) at

Arrays.html#sort(java.lang.Object[])

Then click on the link to the interface Comparable which we have already

discussed once.
