IT is Used to evaluate an Expression. .

Um, there's no such thing (at least as a formal name) as the "Assertion Framework" (or network, depending on how you're feeling).
Java has assertions, as of 1.4ish...that's about it, apart from additional stuff in things like JUnit.

You might need to be more detailed.

You also alternatingly refer to it as the Assertion Framework and Assertion Network. If you simply mean, how does java do assertions, then the answer is trivial.

the assert statement in java is simply a boolean evaluator that expects the conditional statement you supply it to be true, otherwise it throws an error. For example:

assert 1 < 2;
boolean running = true;
assert running;

assert !running; //error
assert 1 > 2; //error
