Mapping SDLC to UML

Dear all,
I'm new to this domain of object oriented analysis and design and I want to know the importance of UML.
And by going through some text books I observed that "Structural diagrams" concept.
What exactly mean by a structural diagram/static diagram (Ex: class diagram).
My intention is to know about that "Structure/static" word.

Please help me regarding this with an example.

An object has 3 things:
1. state
2. behavior
3. identity

What do you mean by identity here?

hashCode() and identity of an object

Dear all,

What exactly hashCode() returns?
I have gone through something like that "an object has its identity".

What exactly mean by an identity of an object?

Is it (identity) what hashCode() returns?
