为什么我写入文件是正常的，但是打印到控制台上面的字符串显示的就不对呢？

public void transWriterByBuf() {

try {

FileInputStream fis=new FileInputStream("./imooc.txt");

BufferedReader br=new BufferedReader(new InputStreamReader(fis));

FileOutputStream fos=new FileOutputStream("./imooc1.txt");

BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(fos));

int n=0;

char[] cbuf=new char[10];

while((n=br.read(cbuf))!=-1) {

String string=new String(cbuf,0, n);

System.out.println(string);

bw.write(cbuf, 0, n);

}

bw.flush();

br.close();

bw.close();

fis.close();

fos.close();

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}catch (IOException e) {

e.printStackTrace();

}

}
