BufferedReader.close介绍

[英]Closes this reader. This implementation closes the buffered source reader and releases the buffer. Nothing is done if this reader has already been closed.
[中]关闭此读卡器。此实现关闭缓冲源读取器并释放缓冲区。如果此读卡器已关闭，则不会执行任何操作。

LineNumberReader  lnr = new LineNumberReader(new FileReader(new File("File1")));

// Finally, the LineNumberReader object should be closed to prevent resource leak
