注意：这不一定是一个int，还可以是string。
string s = sc.next();

public static int hebing(char a[]){
Arrays.sort(a);
int temp1 = Integer.parseInt(new String(a));
return temp1;
}

import java.util.Arrays;
import java.util.Scanner;
public class Main1 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner scanner = new Scanner(System.in);
int n = scanner.nextInt();
int max = -1;
for(int i = 0; i != n; i++){
String s = scanner.next();
char temp[] = s.toCharArray();
max = Math.max(max, hebing(temp));
}
System.out.print(max);
scanner.close();
}
public static int hebing(char a[]){
Arrays.sort(a);
int temp1 = Integer.parseInt(new String(a));
return temp1;
}
}

兄弟，你学什么专业的，感觉很高深的样子，coc还玩吗
