And the problem is: - code does not compile ? (show compiler error messages) - compile but crash at run time ? (show error message with stack dump) - does not display expected behaviour ? (tell us what you expected and what is showed)
The idea of the program is for you to be able to ask the user how much the total was. How much your giving to pay for it. And then calculate the change that you are to give the user back in dollars and coins.
Please let me know if you guys need any information and thank you already to those who have already replied and can help me with this situation.
Sorry for the double post. Not sure if your allowed to or not. Anyway I got alittle farther on the code somehow but I seem to be having another problem.

}
The amount owed and amount given seem to be backwords for some reason. Which makes no sense to me. Is there any way of easily fixing this problem?
Thank you everyone for helping. I am deff going to recomend this site. I actually hit a button on Java and it made my error go away. This prob wasnt the proper way and I dont know how netbeans fixed it for me. But it did. Also I made a silly error of accidently switched around the amount owed and amount given code. Thats why it came out the opposite way.
