这第二个程序怎么编啊

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("输入：");
String n = scanner.nextLine();
System.out.print("输入：");

    String[] nums = scanner.nextLine().split(" ");
    int sum = 0;
    for (String s : nums) {
        System.out.println(s);
        sum += Integer.parseInt(s);
    }
    System.out.println("和为" + sum);
    System.out.println("平均值" + (sum*1.0/ nums.length));
    Arrays.sort(nums);
    System.out.println("排序后" + Arrays.toString(nums));
}
