Book or reference material for UML [closed]

Question

I have about four years of experience as a Java developer. I'm planning to get myself involved in the world of UML. Can anyone suggest some good books and reference material for UML?

Answer 1

UML Distilled, by Martin Fowler.

I have it here, and it's a very good introduction. Actually, it was a "required reading material" for my university, so can be thought of as a textbook as well.

Answer 2

Book Applying UML And Patterns
