public class FileRead {
    public static void main(String[] args) throws Exception {
        File file = new File("D:\\aa.txt");
        InputStreamReader read = new InputStreamReader(new FileInputStream(file),"gbk");
        BufferedReader reader = null;
        String temp = null;
        int line = 1;
        try {
            reader = new BufferedReader(read);
            while ((temp = reader.readLine()) != null) {
                System.out.println("line" + line + ":" + temp);
                line++;
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (Exception e) {
