Java Can'；t将所有列表写入文件

我有一个文本文件中一些行的ArrayList列表。我试图在一个文本文件中找到这些行，如果我找到它，我想将其写入另一个文本文件，并将其从原始文件中删除

我为此写了一个代码，它是有效的，但不是整个列表，有时需要一行，有时需要更多。给我这个信息：

1 R101 100850 0 捕获异常：java.io.IOException:流已关闭

有人能帮我吗

String subLine = line.substring(5, line.length() - 2);

您正在硬编码以从索引5中获取子字符串

当线的长度小于5时会发生什么情况？检查线路长度是否小于5，然后继续

---

还有，为什么要用“异常”捕捉？尝试使用较低级别的异常（如ArrayIndexOutOfBoundsException等）进行捕获。

谢谢大家的帮助

我发现了这个问题，因为我删除了这个文件，并从临时文件中再次创建了它。在这种情况下，我丢失了指向该文件的指针

这是我修复后的代码，如果有人感兴趣

 static void moveLines(ArrayList posList, int topic) {

    //=======================To read lines=======

    try {

        BufferedReader bufferedReader = new BufferedReader(fileReader);

        FileWriter fileWriter = new FileWriter(outputFile);
        BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

        String line;
        while ((line = bufferedReader.readLine()) != null) {
            String subLine = line.substring(5, line.length() - 2);

            if (posList.contains(subLine)) {
                System.out.println(count++ + " " + line);

该异常发生在哪一行？你能把你的墙o’代码缩减到更易于管理的地方，仍然会重现问题吗？它发生在第一个例外中。
