C语言训练-排序问题<1> （Java代码）利用Arrays工具类排序

参考代码:

import java.util.Arrays;

import java.util.Scanner;

public class Main1128 {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

            int[] a = new int[4];

            for (int i = 0; i < a.length; i++) {

            a[i] = sc.nextInt();

            }

            Arrays.sort(a);

            for (int b : a) {

                System.out.print(b+" ");

            }

    }

}
