what are structural and behavioral design patterns

I am new to design patterns and stuck on very basic step : different types of design patterns.

Creational patters are pretty easy to understand.

I just want to understand the simple definition of structural and behavioral design patterns, with explanation in simple terms of java and not in terms of various design patterns.

Note: I read qsns on stackoverflow but I am not clear with the answers. Can anyone explains it in terms of java with simple examples.
