Thread: Help with a few short Java exam questions.

We aren't going to do your homework for you.

Instead of simply posting a screenshot (really?) of your homework, why don't you tell us what you think the answer to each is?

Some of these questions have some issues with them.
#12: it is a bit unclear what they are referring to here. I'm not sure if there is such a thing as a "runtime error" ("runtime exceptions" are certainly a thing).
The only thing wrong with #25 is that the author forgot to close the parentheses, which I don't think is important to the question.
As for #24, consider that when you move your mouse over a JButton, the button state changes. What do you think causes that state change?
#16: given the other mistakes the author made, you might be correct that the intention is for this to be true, but you can create your own listeners and attach them to any random objects you create.
