  1. 代码：
  4. import java.util.Scanner;
  6. public class Ten_six {
  8.     public static void main(String[] args) {
  9.         System.out
  10.                 .println("Enter an int value, the progrem exits if the input is 0: ");
  11.         Scanner cin = new Scanner(System.in);
  12.         int a = 1, s = 0, s1 = 0, s2 = 0;
  13.         double num = 1;
  14.         for (int i = 0; a != 0; ++i) {
  15.             a = cin.nextInt();
  16.             s += a;
  17.             if (a > 0)
  18.                 s1++;
  19.             if (a < 0)
  20.                 s2++;
  21.             num = i;
  22.         }
  23.         System.out.println("The number of positives is " + s1);
  24.         System.out.println("The number of negatives is " + s2);
  25.         System.out.println("The total is " + s);
  26.         System.out.println("The average is " + (s / num));
  27.     }
  28. }
