输出打印初始化的最小值而不是打印更新的一个

Question

下面是我的代码，它应该打印特定小时的最高温度。 它总是在 5 处打印 -1000。

package javaPracticeNotes;

import java.util.Scanner;

public class Lab3_7 {
    public static void main(String[] args) {
        int temp;
        int maxtemp = -1000;
        int timeAtMax = 0;
        int hour;

        for (hour = 1; hour <= 5; hour++) {

            Scanner scan = new Scanner(System.in);
            System.out.println("Enter the temperature at " + hour);
            temp = scan.nextInt();
            if (maxtemp < temp) {
                temp = maxtemp;
                timeAtMax = hour;
            }
        }
        System.out.println("The max temperature of the day was " + maxtemp + " at" + timeAtMax);
    }
}

Answer 1

您的 if 语句是正确的，只需反转temp = maxtemp;

if (maxtemp < temp) {
    maxtemp = temp;
    timeAtMax = hour;
}
