    Default Help with a few short Java exam questions.

    This question has confused me because "Errors" are capitalised and I'm not sure what they mean.

    To me this question is false. Sockets can be used to transfers file over a network.

    I can't see why this wouldn't work. The code looks fine to me.

    I don't think this is true unless you're using the mouseEntered() or mouseExited() method. But again, I'm not sure.

    I think this is true, I don't know what else could have listeners.

    They're only worth a few marks each so the answer is only suppose to be a line or two. They are all true or false questions that require an explanation.

    If you can help on any of them, it'll be greatly appreciated!

    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.

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.
