package study01; import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner sc = new Scanner(System.in); //正數的個數 int count1 = 0; //負數的個數 int count2 = 0; int input = sc.nextInt(); while (input != 0) { if (input > 0) { count1++; } else { count2++; } input = sc.nextInt(); } System.out.println("正數的個數為" + count1 + "," + "負數的個數為" + count2); } }
結果如下:
13
-2
-4
11
-6
0
正數的個數為2,負數的個數為3
