对字符串排序，String可以转为char[]

import java.util.Arrays;
import java.util.Scanner;
public class Main{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String s = sc.nextLine();
		char[] cs = s.toCharArray();
		Arrays.sort(cs);
		for (int i = 0; i < cs.length; i++) {
			System.out.print(cs[i]);
		}
		System.out.println();
		for (int i = cs.length-1; i >=0 ; i--) {
			System.out.print(cs[i]);
		}
	}
}
