Question

System.out.println("How long is the word you would like to guess?");
    while (goodInput==false)
            {
                try
                {
                    wordSize=scan.nextInt();
                    goodInput=true;
                }
                catch(InputMismatchException ime)
                {
                    System.out.println("Thats not a number! Try again");
                }
            }

The console repeats the “Thats not a number…” in infinite loop after the wrong type of input is entered.

*edit

I tried

while(goodInput==false)
        {
            if (scan.hasNextInt())
            {
                wordSize=scan.nextInt();
                goodInput=true;
            }
            else
            {
                System.out.println("Thats not a number! Try again");
            }
        }

which also produces same error

You never consume the input if a non-integer is supplied, so the input is passed through again and again resulting in an infinite loop. You could use:

scan.nextLine();

in your exception block but better to use:

while (scan.hasNextInt() && !goodInput) {
