Hints on Exercise SumAndAverage (Loop)

Hints here are some hints on the Sum and average

public class SumAndAverage {   // saved as "SumAndAverage.java"
   public static void main (String[] args) {
      int sum = 0;          // store the accumulated sum, init to 0
      double average;       // average in double
      int lowerbound = 1;   // the lower bound to sum
      int upperbound = 100; // the upper bound to sum

      for (int number = lowerbound; number <= upperbound; ++number) { // for loop
         sum += number;     // same as "sum = sum + number"
      }
      // Compute average in double. Beware that int/int produces int.
      ......
      // Print sum and average.
      ......
   }
}
