将一个英文语句以单词为单位逆序排放。例如“I am a boy”，逆序排放后为“boy a am I” ...

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    String nextLine = scanner.nextLine();

    String[] s = nextLine.split(" ");
    for (int i = s.length - 1; i >= 0; i--) {
        System.out.print(s[i] + " ");
    }
}

}
