在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔， 如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序， （排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次， 则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开， 最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)

线程的创建、销毁和调度本身是有代价的，如果一个线程的任务相对简单，那这些时间和空间开销就不容忽视了，此时用线程池就是更好的选择，即创建一些线程然后反复利用它们，而不是在完成单个任务后就结束。-thread creation, destruction and scheduling itself is a cost, if the threads of a relatively simple task. That time and space costs can not be ignored, this time using thread pool is the better choice, namely, the creation of some thread then reuse them, rather than individual tasks completed after the end.
