Boas,

Actualmente tenho tido que investigar bastantes padrões Java, pois vou ter de pôr alguns em prática no meu actual projecto, e descobri o seguinte link que tem um bom conjunto de padrões e para que servem.

http://java.sun.com/blueprints/corej2eepatterns/index.html

Este outro, site tem padrões "novos", "em estudo" e "mas porque raio é que alguém quer isto". Para além de ser uma excelente referência para tudo Java, incluindo livros, papers e novas ideias.

Já agora, para quem não sabe o que são "patterns", deixo aqui a explicação da própria Sun.


A pattern describes a proven solution to a recurring design problem, placing particular emphasis on the context and forces surrounding the problem, and the consequences and impact of the solution.

Why Use Patterns?

    *  They have been proven. Patterns reflect the experience, knowledge and insights of developers who have successfully used these patterns in their own work.

    *  They are reusable. Patterns provide a ready-made solution that can be adapted to different problems as necessary.

    *  They are expressive. Patterns provide a common vocabulary of solutions that can express large solutions succinctly.

It is important remember that patterns do not guarantee success. A pattern description indicates when the pattern may be applicable, but only experience can provide understanding of when a particular pattern will improve a design.
