但是要学会排列

然后你才能浪

 import java.util.*;
 public class Main {
     public static void main(String[] args) {
         Scanner sc = new Scanner(System.in);
         ArrayList<Integer> list = new ArrayList<Integer>();
         int n = sc.nextInt();
         for(int i=0;i<n;i++)
             list.add(sc.nextInt());
         Collections.sort(list);
         System.out.println(list.get(list.size()-1));
         System.out.println(list.get(0));
         int x = 0;
         for(int i:list)
             x += i;
         System.out.println(x);
     }
 }
