按照空格拆开,然后逆序输出即可。

代码

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        while (sc.hasNextLine()) {
            String str = sc.nextLine();
            String[] words = str.split(" ");
            for (int i = words.length - 1; i >= 0; i--) {
                if (i == 0) {
                    System.out.print(words[i]);
                    break;
                }
                System.out.print(words[i] + " ");
            }
        }
    }
}
