The first error would seem to indicate that your addDimes method is defined more than once in your class. And a quick inspection of your code indicates that that is indeed the case. If you actually read the error messages, they usually tell you what the problem is. bear
Welcome to JavaRanch, John Walker! Note that you can copy the text from a windows console. To do so, right mouse click on the title bar, go to Edit -> Mark. Highlight the section of text you'd like to copy. Then right mouse click on the title bar again, go to Edit -> Copy and the text contents will be copied to the clipboard. Now, about that name. Is that your real name? We don't require real names 'round these parts, but we don't let suspiciously fictitious ones slide without comment. Your display name reminds me of a girl and a party in a cornfield outside Frankfurt, Germany. I won't bore you with the details of my story. I'll just ask that you change your display name if it ain't real. Hope to see you 'round the Ranch!
