View Full Version : Beginner having some Java class trouble

The "Add Lumber" & "Add Customer" sections aren't working correctly. Eclipse tells me that I haven't added the while statement; is there something else wrong? I added a comment saying "Need to find out which one the customer wants." I need to ask the customer if they want to edit the price or stock level. I don't know specifically how. Any advice would be appreciated. I'm almost done with the program I just need these errors/problems fixed.

You'll need to run this through the formatter first, then repost it. Its too difficult to follow as is.
If its complaining about a 'while', it means you have a do without an enclosing while condition. That indicates a problem with your close brace positioning (which will be easier to see after you let eclipse format it).

Under modify customer you need another brace. The current one only corresponds to the for loop.


number[count] = ID_number;
firstname[count] = first_name;
lastname[count] = last_name;
address[count] = Address;
creditlimit[count] = Cred_Lim;
}}while (more.equals("Y"));
