Question Details:
Write a program that reads any number of integers from the keyboard, then
calculates and prints the average.  Assume the last value read is the sentinel (exit
condition) 9999.  The sentinel, 9999, should not be included in the average.  
Name the .java file Lab7_Ex2.
 
Example input/output:
 
Enter any number of integers (enter 9999 when done):
8 [enter]
11 [enter]
7 [enter]
9 [enter]
2 [enter]
9999 [enter]
 
The average is 7.4

Response Details:
public static void main(String[] args)
{      
      // open user input stream
      Scanner kb = new Scanner(System.in);

      // input numbers while the input is not 9999
      int input;

      // store total and count of numbers inputted
      double total = 0.0;
      int count = 0;
     
      System.out.println("Enter any number of integers (enter 9999 when done): ");

      while((input=kb.nextInt())!=9999)
      {
            total += input;
            count++;
      }      

      // calculate average
      double average = total / count;

      // output
      System.out.println("The average is "+average);
}
