These writings doesn’t dwell into the patterns deeply and are written just to give an idea of what they are ( for dummies remember ). The real challenge is identifying the problem rather than the pattern implementations. Although there are as many patterns as discussed, it is not necessary to implement all of them in any project. We’ll have to contemplate on the problem and see what fits in to our project.

Its was fun going through all off these patterns and hope you readers have enjoyed and learnt a few things from it.

P.S You can find the UML class diagrams to all of these patterns from dofactory site
