Specifically tell us what problems you are having, what you have tried and any errors you get. Read the announcement at the top of the forum. We can't read your mind and know what you need help with.

Also try putting the post with the tags. It becomes more easy to read and identify problems

if you illustrate me the problem clearly maybe i can help...I didn't get the problem...

import java.util.*;

public class ChangeMakerJ

static Scanner console = new Scanner(System.in);

Don't do their work for them.
