I am stuck trying to figure out syntax errors in program.
Would appreciate help.

Thank You In Advance :D

These are the errors:

Edited 3 Years Ago by happygeek: fixed formatting

I'll help you with the System.outs to get rid of the bulk of the problem, but I am very sick right now, or else I would help you fix all of it.

System.out.print("Cannot find specified item -" \' + item + \');

should be something like this"

System.out.print("Cannot find specified item -" + "\\" + item + "\\");

also, if you want to convert an int to a string, do it like this:

int index = Integer.parseInt(findItemIndex(item));

Sorry I can't help right now...

Thank you server crash that helped with those issues that I was having.

I am still open to other suggestions because I am still getting these error messages:
