    Good job on finding that, not going to fix it though.

    Basically in my code I take the page number and subtract it by 1. Then I check if it's lower than 1.

    However what happens is, because you inputted the lowest possible value for a signed integer in Java, due to the integer overflowing, subtracting -2147483648 by 1 actually gives a positive number 2147483647, meaning it passes the lower than 1 check, and therefore just shows an empty list instead of giving the usual "number must be between 1 and x" error message
