What are some good resources to learn designdesign patterns?
Design patterns are a great concept that are hard to apply from just reading about them. Take some sample implementations that you find online and build up around them. A great resource is the Data & Object Factory page. They go over the patterns, and give you both conceptual and real world examples. Their reference material is great, too.
What are designdesign patterns?
Design patterns are just tools–kind of like library functions. If you know that they are there and their approximate function, you can go dig them out of a book when needed. There is nothing magic about design patterns, and any good programmer figured 90\% of them out for themselves before any books came out.
What are the best resources for Learning Object Oriented Design?
A great resource is the Data & Object Factory page. They go over the patterns, and give you both conceptual and real world examples. Their reference material is great, too. Some people already mentioned, practice and refactoring.
Should I start with factory or design pattern first?
Most of today’s developers have experienced some good or bad incarnation of a Factory, so starting with Factory can lead to a lot of conversation and confusion about the pattern.This tends to take focus off how to study and learn patterns which is pretty essential at that first meeting. I recommend HeadFirst DesignPattern.
