Find Bugs - A static analysis tool to find logical error in given code snippet. Basically it helps find bugs in Java code. This comes as an Eclipse plug-in.
There is a way you can integrate Find bugs into the source control you are using for example Perforce.
This should be integrated on each and every development environment of developer's whether Eclipse or IntelliJ. As you go on writing code, this tool will immediately display errors which could cause eventually potential bugs with coding right away. So it saves time of developers handing over code to QA, QA performs testing and reporting back these bugs.
