Suppose we write the following Comparator:

import structure5.*;

import java.util.Iterator;

import java.util.Comparator;

import java.util.Scanner;

public class RevComparator implements Comparator

{

protected Comparator base; public RevComparator(Comparator baseCompare)

{

base = baseCompare;

}

public int compare(T a, T b)

{

return -base.compare(a,b);

}

What happens when we construct:

MyVector v = new MyVector();

Scanner s = new Scanner(System.in);

while (s.hasNextInt())

{

v.add(s.nextInt());

}

Comparator c = new RevComparator(new IntegerComparator());

v.sort(c);
