Multiple strings.xml files cause order and incomplete problems in android

there is a boring task, boss let me check multiple strings.xml files to find the differences  compare to res/values/strings.xml.  Jesus christ!  It's 33 kinds of languages in android. I do not want work like a idiot. so, I wrote a program to solve that stupid task.

here is my code.

package com.jack.filter;

import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.file.FileVisitResult;
import java.nio.file.FileVisitor;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

 * 不能在安卓項目中使用!!!!
 * 思路: 
 * 		給定一個res路徑,遍歷讀取以values-開頭的目錄存到集合中
 * 讀取目錄下的strings.xml文件,將數據轉爲鍵值對HashMap<String,String> source---("XXX","<string name="XXX">ZZZZ</string>");
 * 遍歷values/strings.xml默認文件,逐行讀取String readLine,同時聲明一個List<String> tem; 
 * 		如果該行爲<string name="XXX">ZZZZ</string>則提取鍵XXX,如果匹配到source則tem.add(source.get(key));
 * 		如果該行沒有key(註釋)或者XML文件頭,或者沒有匹配的則直接tem.add(readLine);
 * 
 * 注意事項:
 * 		不能在安卓項目中使用! 需要新建一個Java project運行,導入的包全爲java.nio.* 下的子類
 * 		如果報錯則添加JRE Library
 *
