        System.out.println("for loop i is completed.");

        if (foundIt)
        {
            System.out.println("Found " + searchfor + " at " + i + ", " + j);
        }
        else
        {
            System.out.println(searchfor + " not in the array");
        }

    }
}
Output
i:0
arrayOfInts[0][0] : 1
arrayOfInts[0][1] : 2
for loop i is completed.
