说明：  编写一个Java应用程序，开启一个文本文件（以本程序源文件为例读取），一次读取其内的一行文本，令每行形成一个String，并将读出的String对象置于LinkedList中，以相反次序显示出LinkedList内的所有内容
(Write a Java application, open a text file (in this program read the source file for example), one reads a line inside the text, so that every row to form a String, the String object will be read out LinkedList placed in in reverse order show all of its contents LinkedList)
