本文實例講述了Java實現英文句子中的單詞順序逆序輸出的方法。分享給大家供大家參考，具體如下：

題目要求：給定n行的英文句子，要求輸出句子中逆序單詞后的句子，如:

輸入：n=3
I love you
How are you
My name is Liming

輸出：

you love I
you are How
Liming is name My

依據Java語言給我們提供的拆分空格間隔的單詞的方法(split(" "))，倒序輸出即可;

實現代碼：

									import java.io.UnsupportedEncodingException;

									import java.util.Scanner;

									public class Main {

									    public static String reverseWords(String sentence) {

									        StringBuilder sb = new StringBuilder(sentence.length() + 1);

									        String[] words = sentence.split(" ");

									        for (int i = words.length - 1; i >= 0; i--) {

									            sb.append(words[i]).append(' ');

									        }

									        sb.setLength(sb.length() - 1);

									        return sb.toString();

									    }

									    @SuppressWarnings("resource")

									    public static void main(String[] args) throws UnsupportedEncodingException {

									        Scanner in = new Scanner(System.in);

									        System.out.printf("Please input how many lines you want to enter(test by jb51): ");

									        String[] input = new String[in.nextInt()];

									        in.nextLine();

									        for (int i = 0; i < input.length; i++) {

									            input[i] = in.nextLine();

									        }

									        System.out.printf("\nYour input:\n");

									        for (String s : input) {

									            System.out.println(reverseWords(s));

									        }

									    }

									}
