April 15th, 2006 In my experience much of the complexities a newcomer faces in the Java world is understanding extraneous stuff like handling exceptions or formatting data etc. Today I was requested for the nth time (n -> infinity) how to write a simple socket client and server (actually debug one).

Static Analysis tools like FindBugs can enhance the security of your Java applications (web as well as standalone or client-servers applications) in several significant ways.
