读取一行数据，使用空格分割开得到一个数组，然后数组逆序组装到StringBuilder中输出。

import java.io.*;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String value = br.readLine();
        String[] values = value.split(" ");
        StringBuilder sb = new StringBuilder();
        for(int i=1;i<=values.length;i++){
            sb.append(values[values.length-i] + " ");
        }
        System.out.println(sb.toString());
        br.close();
    }
}
