isInteger will not seem to work
I am making a work oganization app and focusing on a method that checks if you wrote the date incorrectly and will prompt you to rewrite it if you did. This is in the unacceptabledate method in the file. First I need to make sure that integers are being written in the date. I cant seem to use isInteger though. I tried toString and Integer.parsrInt and tried using isInteger after but nothing has worked. Please help
