    现在一些关于怎么样对待java中Files, Streams, Connections 和 其他任何"closeable"对象的一些建议。就简单的以FileWriter类和一段错误使用的它的bug代码：

    public void writeToFile(String fileName, String content) {        try {            FileWriter file = new FileWriter(fileName);            try {                performWriteToFile(file, content)            } finally {                file.close();            }        } catch (IOException e) {            // Log the exeception        }    }    // Here we perform all the operations on the file.    // This method usually is much longer.    private void performWriteToFile(FileWriter file,            String content) throws IOException {        file.write(content);    }
