Answer 1

Take a look at this link

Answer 2

Your code needs to be separated. Find a way to make the answer always capital that way you can take out the cases for lower case, or make separate cases.

The way you have it setup is...ugly. I can't even tell if it's because the switch runs into two cases or because it runs into a case without code and a break.

otherwise it will work (assuming you got no compile errors)

Answer 3

First, add extra lines between your switch statement.

Second, you need to check for a null first before you enter your switch,


use the statement
shipcode = shipcode.toUpperCase6() to get the upper case.

Answer 4

^ewwwww^ ugly
