> What is synchronization?

Preventing concurrent access by more than one thread.

> and what does immutable

An object that cannot have its state changed is said to be immutable.

> Are they related?

No. Yes. Somewhat. Given the above explanations, can you think of something relevant? Think about what could be the dangers of unguarded concurrent access, and how that relates to mutability.

You are really incredibly lazy, aren't you.
