PTA 循环结构测试 java

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String input = scanner.nextLine();
        String[] heightStr = input.split(" ");
        int totalHeight = 0;
        int count = 0;

        for (String height : heightStr) {//迭代器循环字符串数组
            int heightValue = Integer.parseInt(height);//将每个字符数组转化为整数，记录每个人的身高
            if (heightValue == 0) {
                break; // 输入结束
            }
            totalHeight += heightValue;
            count++;
        }

        if (count > 0) {
            int averageHeight = totalHeight / count;
            System.out.printf("一共输入了%d个人的身高，平均身高是%d%n", count, averageHeight);
        } else {
            System.out.println("没有输入有效的身高数据。");
        }

        scanner.close();
    }
}
了解的知识：迭代器，字符的转化，利用字符串数组进行多个数字的输入
