java 一个数组，随机生成10个数，并求这些数的最大值、最小值、和、平均值

public class Demo7 {

    public static void main(String[] args) {

        int[] arr = new int[10];
        for (int i = 0; i < arr.length; i++) {
            arr[i] = (int) (Math.random() * 1000);
        }
        for (int i = 0;i arr[i]){
                min = arr[i];
            }
        }
        System.out.println("最小值:" + min);
        //和
        int sum = 0;
        for (int i = 0;i < arr.length;i++){
            sum += arr[i];
        }
        System.out.println("和:" + sum);
        //平均值
        double avg = 1.0 * sum / arr.length;
        System.out.println("平均值:" + avg);
    }
