簡單的從一行輸入的字串中通過特定的字元將字串切割成幾個字串, 簡單的題目, 程式碼如下:

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {

    public static void main(String[] args) throws Exception{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String[] str 
 
= br.readLine().split("-");
        System.out.println(str[2]+"-"+str[0]+"-"+str[1]);
    }

}
