From your stack trace:

Exception at thread "main" java.util.InputMismatchException
at java.util.Scanner.throwfor{Scanner.java:909}
at java.util.Scanner.next{Scanner.java:1530}
at java.util.Scanner.nextInt{Scanner.java:2160}

at StudentGrades.main{StudentGrades.java:20}

the Exception is being thrown by your call to nextInt.

Thus, you're getting an exception because you're requesting an integer and the Scanner is finding something that's not an integer.
