读文件异常：java.nio.charset.MalformedInputException

今天写一个读文件的程序

Path path = Paths.get("d:" + File.separator + "medical.txt");
		BufferedReader reader = Files.newBufferedReader(path);
		
		Path resultPath = Paths.get("D:" + File.separator +"medical dictionary");
		String line = null;
		while ((line = reader.readLine()) != null) {
			line = line.split(" ")[1] + " 1\n";
			Files.write(resultPath, line.getBytes(), StandardOpenOption.APPEND);
		}

但是在执行第二行‘Files.newBufferedReader(path);’时，出现异常：java.nio.charset.MalformedInputException: Input length = 1。该异常类的描述如下：

/**
 * Checked exception thrown when an input byte sequence is not legal for given
 * charset, or an input character sequence is not a legal sixteen-bit Unicode
 * sequence.
 *
 * @since 1.4
 */

public class MalformedInputException

然后看了下newBufferedReader方法

public static BufferedReader newBufferedReader(Path path) throws IOException {
        return newBufferedReader(path, StandardCharsets.UTF_8);
    }

而我要读的文件呢，是GBK！

也就是说，只要用GBK格式来读就可以了。修改如下：

Path path = Paths.get("d:" + File.separator + "medical.txt");
		BufferedReader reader = Files.newBufferedReader(path, Charset.forName("GBK"));
		
		Path resultPath = Paths.get("D:" + File.separator +"medical dictionary");
		if (Files.exists(resultPath)) {
			Files.delete(resultPath);
		}
		Files.createFile(resultPath);
		
		String line = null;
		while ((line = reader.readLine()) != null) {
			line = line.split(" ")[1] + " 1\n";
			Files.write(resultPath, line.getBytes(), StandardOpenOption.APPEND);
		}
