File source = new File("D:/temp1.txt");
        File distination = new File("D:/temp2.txt");
        try {
            FileInputStream fis = new FileInputStream(source);
            BufferedReader reader = new BufferedReader(new InputStreamReader(fis,"gbk"));
            FileOutputStream fos = new FileOutputStream(distination);
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(fos,"gbk"));
            String temp ;
            while((temp = reader.readLine())!= null){
                writer.write(temp.substring(0,temp.length()-2));
                writer.newLine();
            }
            writer.flush();
            writer.close();
            reader.close();
            fis.close();
            fos.close();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
