Answer 1

Your problem is in line 20.

grades[studentNumber][courseNumber] = input.nextInt();

that means that in the input, it is expecting an int, but it founds another thing, like a double, a char array or anything else

There is also another problem, you declare your grades as:

grades = new int[5][3];

the last number means that you can access to grades from [0..4][0..2]

but your if statement:

if (courseNumber < 5) 

means that you will access to a number higher than '2' in

grades[studentNumber][courseNumber] = input.nextInt();

which will raise an OutOfBoundsException
