打开第11 章中讲到的IOStreamDemo.java 文件，一次读取其中的一行，令每行形成一个String 对象。然后利用java.util.Comparator 接口重新定义String 对象间的比较方法：将每个String 中的小写字母转为大写后再进行比较。使用该比较法对这些String 进行排序，按从大到小的顺序存入一个LinkedList。最后将LinkedList 中的String 按存入的相反顺序输出到另一个文件inverse.txt 中。-Open the IOStreamDemo.java file in the eleventh chapter, a line to read, so that each line to form a String object. Then use the java.util.Comparator interface to redefine the String object

Comparison method: the lower case letters in each of the String to the capital after the comparison. Using the comparison

Method to sort these String, in order to deposit a LinkedList　large to small. In the end, the String of the LinkedList is stored in the opposite order of the inverse.txt.
