Why doesn't my “While Loop” print the computation of finding the average “score”?

Question

I am writing a program that reads a sequence of positive integers input by the user. User will only enter one integer at a time.Then it will compute the average of those integer

Answer 1

The problem is that the input.nextInt() should be part of the loop. The way you wrote it, the code gooes into an infinite loop whenever the first input is non-zero. Instead, do:

while ((integer = input.nextInt())  != 0) {
  count = count + 1;  
  sum = sum + integer; 
  average = sum / count;
}
