在Java程序（Java 1.5）中，我有一个BufferedWriter，它包装了Filewriter，并且多次调用write（）...结果文件很大...

在此文件的各行中，其中一些是不完整的...

我每次写东西时都需要调用flush（但是我怀疑这样做效率不高）还是使用BufferedWriter的另一种方法还是使用另一种类...？

（由于我要编写的行数不胜数，所以我确实希望有一些高效的东西。）理想的“冲洗”时刻是什么？（当我达到BufferedWriter的容量时）...

在里面：

try {
  analysisOutput = new BufferedWriter(new FileWriter(
      "analysisResults", true));
  analysisOutput.newLine();
  analysisOutput.write("Processing File " + fileName + "\n");
} 
catch (FileNotFoundException ex) {
  ex.printStackTrace();
} 
catch (IOException ex) {
  ex.printStackTrace();
}

写作：

private void printAfterInfo(String toBeMoved,HashMap<String, Boolean> afterMap, Location location)
  throws IOException {
    if(afterMap != null) {
      for (Map.Entry<String, Boolean> map : afterMap.entrySet()) {
        if (toBeMoved == "Condition") {
          if (1 <= DEBUG)
            System.out.println("###" + toBeMoved + " " + location + " "
                + conditionalDefs.get(conditionalDefs.size() - 1)
                + " After " + map.getKey() + " "
                + map.getValue() + "\n");

          analysisOutput.write("###" + toBeMoved + " " + location + " "
              + conditionalDefs.get(conditionalDefs.size() - 1)
              + " After " + map.getKey() + " " + map.getValue()
              + "\n");
        } else {
          if (1 <= DEBUG)
            System.out.println("###" + toBeMoved + " " + location + " "
                + map.getKey() + " After " 
                + map.getValue() + "\n");
          if (conditionalDefs.size() > 0)
            analysisOutput.write("###" + toBeMoved + " " + location + " "
                + conditionalDefs.get(conditionalDefs.size() - 1) + " "
                + map.getKey() + " After " + map.getValue()
                + "\n");
          else
            analysisOutput.write("###" + toBeMoved + " " + location + " " + map.getKey() + " After " + map.getValue() + "\n");


        }
      }
    }

我刚刚发现，不完整的行就是“正在处理文件”之前的行...因此，当我从一个要分析的文件切换到另一个文件时，就会发生该行...

闭幕：

dispatch(unit);

try {
  if (analysisOutput != null) {
    printFileInfo();
    analysisOutput.close();
  }
} 
catch (IOException ex) {
  ex.printStackTrace();
}

有时，由printFileInfo打印出的信息不会出现在结果文件中。
