I am working on java programming that converts zipcode to barcode an.pdf

I am working on java programming that converts zipcode to barcode and vice versa. I am stuck
in as the instruction requires that I have to use two methods which are getBarcode and
getZipcode to the tester. For this reason, it seems like that I have to call all the methods before
those two methods. However, I think the if statements and swich are not working properly as the
result also is not calling proper results.
Please review what is wrong in this code.
Question: How can I call the methods before getBarcode and getZipcode Question: Is there
anything wrong among switch and if statements?
Question: As the zipcode and barcode should be called as String, Which methods should I use
for changing the Strings into integers?
