java从键盘输入5个整数存入数组，由大到小排序后输出数组中所有元素。（必须使用循环）

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int[] arr = new int[5];
        for (int i = 0; i < arr.length; i++) {
            System.out.print("请输入第" + (i + 1) + "个整数：");
            arr[i] = scanner.nextInt();
        }
        //排序
        for (int i = 0; i < arr.length - 1; i++) {
            for (int j = i + 1; j < arr.length; j++) {
                if (arr[i] < arr[j]) {
                    int temp = arr[i];
                    arr[i] = arr[j];
                    arr[j] = temp;
                }
            }
        }
        //输出
        for (int i = 0; i < arr.length; i++) {
            System.out.print(arr[i] + " ");
        }
    }
}
