我有这样的想法:

...
while (itr.hasNext()) {
...
try {

    if (userInput.equalsIgnoreCase(theData.getName())
        || (country.getName().toString()).equalsIgnoreCase(theData.getName()))
       {

        result = new Country(PointT, dist);
        break;

      } else {

        for (int i = 0; i < repl.size(); i++) { 

          if (repl.get(i).toString().contains(theData.getName())) {

            theName = true;
            result = new Country(PointTt, dist, theName);
            break;
          } else if (theParts.get(i).toString().equalsIgnoreCase(theData.getName())) {
            result = new Country(PointT, dist);
            break;
          } 
        } 


      }
    } catch (NoSuchElementException ex) {
      logger.error("Does not exist in database", ex);
      throw ex;
    } catch (NullPointerException ex) {

      logger.error("Does not exist in database", ex);
      throw ex;
    }catch (Exception ex) {
      logger.error("Does not exist in database", ex);
      throw ex;
    }
}
...

theData.getName() 这个 userInput country.getName() repl.get(i) List<String> , theParts.get(i) 列表(<);字符串(>);

(theData.getName()) .

读取数据

为了阅读 theData :

我正在使用 FileInputStream fis = new FileInputStream(filelocation);

然后,仅提取字符串并存储它们:

ArrayList<String> theNames = new ArrayList<String>();

然后我合并 theNames 与其他迭代器一起创建

ArrayList<theNamesLoc> theNamesLocList = new ArrayList<theNamesLoc>();

这是我应用的数组列表:

Iterator<TheNamesLoc> itr = theNamesLocList.iterator();

while (itr.hasNext()) {

..}
