String line

While ((line = br.readLine ())! = null) {

System.out.println (line)

}

Br.close ()

If it is to read pictures, video, audio class asking price with byte stream.

The difference between byte stream and character stream:

Character stream is more efficient than byte stream (char accounts for 2 byte in java) Byte stream can read all files. For example, audio and video character streams need to refresh the buffer every time they write the file to the buffer.

The byte stream writes the data directly to the file each time without flushing the buffer
