Why are there no need for throws?
I was under the impression that adding throws to the method(The method that does not want to handle the exception) allows the exception to propagate down the stack.

Because NullPointerException is a RuntimeException. RuntimeExceptions don't need to be declared in the throws clause.

Why the answer for no. 1 is AssertionError() and not the IllegalArgumentException()?
