题意：
就是输入数字#和-，数字1-26分别对应A-Z.
#对应空格 -没有含义，就是把数字隔开

注意这一种输入：
1
###—##

两种方法：
一,常规方法：

import java.util.Scanner;

public class Main{

    static char[] STR={'a','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int t =sc.nextInt();
        while(t-->0){
            String str=sc.next();
            String s[] = str.split("-");
            for(int i=0;i<s.length;i++){

                String strN = "";
                for(int j=0;j<s[i].length();j++){
                    if(s[i].charAt(j)!='#'){
                        strN+=s[i].charAt(j);
                    }else{
                        if(!strN.equals(""))
                            System.out.print(STR[Integer.parseInt(strN)]);
                        System.out.print(" ");
                        strN="";
                    }
                }
                if(!strN.equals(""))
                    System.out.print(STR[Integer.parseInt(strN)]);
            }
            System.out.println();
        }
    }
}

二：利用Java中的replaceAll()方法：

import java.util.Scanner;

public class Main{

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int t =sc.nextInt();
        while(t-->0){
            String str=sc.next();
            str=str.replaceAll("#", " ");
            for(int i=26;i>=1;i--){
                String a=""+(char)('A'+i-1);
                String b=""+i;
                str=str.replaceAll(b, a);
            }
            str=str.replaceAll("-", "");
            System.out.println(str);
        }
    }

}
