java - 在java中从数组中查找最小值

Question

我正在尝试从数组中的用户输入中获取总和、平均值、最大值和最小值。 sum、average 和 max 给出了正确的输出。但是最小值不起作用。我哪里做错了，有人可以帮我找出答案吗？

import java.util.Scanner;

public class minMaxSumAverage {
    public static void main(String args[]) {
        int n, sum = 0, max, min;
        double average = 0;

        Scanner s = new Scanner(System.in);
        System.out.println("Enter elements you want to input in array: ");
        n = s.nextInt();
        int a[] = new int[n];
        max = a[0];
        min = a[0];
        System.out.println("Enter all the elements:");
        for (int i = 0; i < n; i++) {
            a[i] = s.nextInt();
            sum += a[i];
            average = (double) sum/a.length;
            if (a[i] > max) {
                max = a[i];
            }
            if (a[i] < min) {
                min = a[i];
            }
        }
        System.out.println("Sum is: " + sum);
        System.out.println("Average is: " + average);
        System.out.println("Max is: " + max);
        System.out.println("Min is: " + min);
    }
}

输出:

Enter elements you want to input in array: 
5
Enter all the elements:
25
5
10
6
4
Sum is: 50
Average is: 10.0
Max is: 25
Min is: 0

最小值应为 4。

Answer 1

我已经更新了你的代码。请检查以下代码以从所有元素列表中获取最小值。

输入:

在数组中输入要输入的元素:

5

输入所有元素:

25

5

10

6

4

输出:

总数是:50

平均值为:10.0

最大值为:25

最小值为:4
