编写Java程序Task6_2.java，定义一个数组，数组一共有5个元素，接收用户输入的5个数，找出最大值和最小值输出。

运行效果如下

public class Max {

public static void main(String[] args) {
    int[] numbers = new int[5];
    Scanner sc = new Scanner(System.in);

    for (int i = 0; i < numbers.length; i++) {
        System.out.println("请输入第"+ (i+1) +"个数字");
        int s = sc.nextInt();
        numbers[i] = s;
    }
    int max = numbers[0];
    int min = numbers[0];
    int count = 0;
    for (int i = 0; i < numbers.length; i++) {
        count+=numbers[i];
        if (max < numbers[i]) {
            max = numbers[i];
        }
        if (min > numbers[i]) {
            min = numbers[i];
        }
    }
    double avg= count/5.0;
    for (int number : numbers) {
        System.out.print(number +" ");
    }
    System.out.println("中最大值为:" +max +",最小值是:" +min +",总分是:" + count+",平均分是:" +avg);
}

}

import java.util.Scanner;
