将字符串按单词翻转

// 将字符串按单词翻转，如 here you are 翻转成 are you here

public class test  {
    public static void main(String[] args) {
        String s="here you are ";
        String[] words = strReverse(s).split("\\s");       //将字符串翻转后再分割，you are here 翻转后为： ereh era uoy
                              //调用字符串自带的分割方法split，“\\s”表示以空格为划分 将原串分割为 ereh era uoy  字符串数组
        StringBuilder sb=new StringBuilder();               //用于存放翻转后的单词
        for (int i = 0; i < words.length; i++) {            //遍历字符串数组,将单词翻转
            sb.append(strReverse(words[i])+" ");            //存放翻转后的单词
        }
        System.out.println(sb.toString());

        StringBuilder sb=new StringBuilder(s);
