    Default Re: Scanner code won't work

    Every time I make a main and a sub I get this error! I always end up messing around with the folders until it works but it doesn't make sense! I always create and save the main within the same sub folder

    Hi r19ecua, I'm beginning programmer so my knowledge is very very limited but I went and copy/pasted your code into eclipse and tried to run it. It worked perfectly fine for me, although after a few trial runs with your program, the change doesn't round out(i.e. change is 1.0999999999999996 instead of 1.10). So I think you're code is perfectly fine and you're in the right direction as for the error.

    I also copied and paste your code into my compiler & it compiled and ran totally fine. So, there is NO error in your code. I guess it's the problem with saving these two files. Remember to save the main and the CashRegister class inside the same folder. Don't create one folder and put each file into different file even if it's under the sub directory. Save the BOTH file inside one file then try to compile and run the program. I am pretty sure it will work out this time.
    Good luck!

    All of the programs are inside the same SRC folder! It's JcreatorPro/MyProjects/CashRegister/Src/InputTester
    JcreatorPro/MyProjects/CashRegister/Src/CashRegister

    I don't understand what's wrong???
