It's a good idea to initialize your values to the opposite of what they represent before going into the loops.
int low = Integer.MAX_VALUE; int high = Integer.MIN_VALUE; But a better solution would be to do everything in the first loop:
int length = 12; for (int count = 0; count < length; count++){ System.out.println("Please Enter in the score: "); int value = inputTest.nextInt(); if (value < low) { low = value; } if (value > high) { high = value; } totaltotalScores += value; } average = (totalScores * 1.0) / length;
