Java没有'；尽管输入为真，但似乎与正则表达式不匹配

长时间的用户，但新的海报，我有一个非常令人沮丧的问题，我似乎无法调试。我有一个为理论练习进行语音搜索的程序。通过标准输入接收输入。 所以

但结果似乎表明，尽管从名单中看到了一个对手，但没有对手

非常感谢您的帮助。

您是否打印了

目录。获取（directorykey）

查看它是什么？是的，在我的目录输入的末尾似乎有一些空白。所以Jns实际上是“Jns”。我现在就试试看，看能不能解决我的问题。

  private static String search(){
  Iterator<String> searchKeyIterator = search.keySet().iterator(); 
  Iterator<String> directoryKeyIterator = directory.keySet().iterator(); 
  String output = new String();

  //Loop through the search terms
  while(searchKeyIterator.hasNext()){
      String searchkey = searchKeyIterator.next(); 
      Pattern searchRegex = Pattern.compile(regexBuild(search.get(searchkey))); 

      output += "\n" + searchkey + ": ";

      while(directoryKeyIterator.hasNext()){
          String directorykey = directoryKeyIterator.next();

          Matcher m  = searchRegex.matcher(directory.get(directorykey));
          boolean b = m.matches();

          if(b == true){
              output += directorykey + ", ";

          }
      }

      output = output.substring(0, output.length() - 2);
  }
    return output;}
