統計輸入的數字為正數和負數的個數

import java.util.Scanner;
public class day01{
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    boolean boo = true;
    int positiveNumber = 0;//正數
    int negativeNumber = 0;//負數
    while (boo) {
      System.out.println("請輸出一個數字：");
      int number = sc.nextInt();
      if (number>0) {
        positiveNumber++;
      }else if (number<0) {
        negativeNumber++;
      }else {
        break;

      }
    }
    System.out.println("正數個數為："+positiveNumber+"負數個數為："+negativeNumber);
  }
}
