Answer 2

The book about design patterns is called Design patterns - elements of reusable object-oriented software.

It is not specifically for Java (written before Java was created), but the object-oriented concepts are clear.

Wikipedia lists and explains all patterns included in that book.

Answer 4

Well, before to reply, I would like to remind you that there is a site, on the interweb, that has a little less anwsers than StackOverflow, but that may, sometimes, with the proper query, give you smart replies.

People call it "google". You simply enter your query, and it gives you the replies, like

• Design patterns in Java
• The design pattern Java companion
• Java design patterns reference and examples
• J2EE design patterns

Answer 5

http://en.wikipedia.org/wiki/Design_pattern_(computer_science)

Generally, there is also a Java implementation for each pattern, together with examples.
