【Kay】Java判断正数和负数个数

Java输入一串数字，输入0则返回正数和负数个数

import java.util.Scanner;
public class nummm {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        int posi = 0;
        int nega = 0;
        while(true){  //写true的话循环会一直进行，写1=1也行，想结束用break。while(true) = for(;;)
            int num = input.nextInt();
            if (num > 0){
                posi+=1;
            }else if(num<0){
                nega+=1;
            }else{
                System.out.println("正数个数"+posi);
                System.out.println("负数个数"+nega);
                break;
            }
        }
    }
}
