a great way of improving your java code: findbugs!

We decided to make our project's code more robust and bug-free. I suggested the use of Findbugs which is basically a program that uses static analysis to search for bugs in your java code. It can be used as IDE plug-in or as a stand-alone application. Findbugs pinpoints problematic places in your code. There are many type of pre-defined problems that Findbugs looks for like duplicate case branches in switch statements, streams which are not closed in all cases, inefficient use of map iterator, redundant comparison to null ... etc. I can't recommend Findbugs enough.
