Not sure if I should even bother to go and clean this code up and make it simpler. Probably not, best thing to do is just scrap it, and use python or a bash script for this.
Hey you can get off the floor now. What would’ve caused me to write stuff like this? Simply because I was a Java weanie and that’s what Java causes you to do. Try to write code that is flexible and over-engineered. Think about it, if it’s a Java project and there’s a database involved the team says ‘Oh we need an ORM, let’s use Hibernate’ without first asking do we really NEED a database in the first place.
Or when writing a web ui, ‘we need a web framework: Struts (yes I’m dating myself), or Seam (that’s the new hotness isn’t it?)’ The question should probably be ‘should I really use Java for my webui at all?’ Answer is an obvious ‘No! use Ruby or Python for it’ You’ll thank me later.
The next time you’re about to choose a framework or any tool, ask yourself ‘is this really the right tool to solve the problem?’
