I wrote three classes for a colleague of mine (I'm new at this job). They compile just fine, but he tells me there are "defects, bugs, and style problems." He wants me to print the files out and mark the problems such as the standard coding conventions, best practices, format, design, and logic. I wrote this code when I was extremely tired and I plan to rewrite it completely. My mistake was showing to it before looking it over myself again. However, he still wants me to do the markings on paper. Any input is greatly appreciated!

The three Java classes ['Station.java', 'ParserInt.java', 'ParserException.java'] are uploaded here: http://www.megaupload.com/?d=N2CUVSV2
