英文句子反转 -- 面试题(Java)

中文的句子我还没试过,一家外企的面试题,题目大约就是把一句英文句子反转。当时我写的很乱,回家后整理到自己的印象笔记上了。有一段时间了,感觉这个写的也不是很好。以后有时间再整理下。

public class SentenceReverse {

	public static void main(String[] args) {
		SentenceReverse sReverse = new SentenceReverse();
		Scanner input = new Scanner(System.in);
		
		System.out.print("Pls enter the sentence you would like to reverse:");
		String sentence = input.nextLine();
		sReverse.reverseSentence(sentence);
	}
	
	public void reverseSentence(String sentence) {
		
		//英文句子,将传入的字符串参数按照空格拆分成字符串数组
		String[] words = sentence.split(" ");
		//JavaScript的数组自带reverse方法,Java的String数组无此方法;
		//将字符串数组存入数组集合中,集合中有reverse方法
		List<String> wordsList = new ArrayList<String>();
		for (int i = 0; i < words.length; i++) {
			wordsList.add(words[i]);
		}
		//省略遍历,直接打印输出数组(反转前的顺序:)
		System.out.println("句子拆分后:");
		System.out.println(Arrays.toString(words));
		//反转单词后遍历输出
		Collections.reverse(wordsList);
		System.out.println("反转后:");
		for (String word : wordsList) {
			System.out.print(word + " ");
		}
	}

}

输出:

Pls enter the sentence you would like to reverse:Even though I try I can't let go

句子拆分后:

[Even, though, I, try, I, can't, let, go]

反转后:

go let can't I try I though Even
