        int read​(CharBuffer cb)
          throws IOException
        Attempts to read characters into the specified character buffer. The buffer is used as a repository of characters as-is: the only changes made are the results of a put operation. No flipping or rewinding of the buffer is performed.
        cb - the buffer to read characters into
        The number of char values added to the buffer, or -1 if this source of characters is at its end
        IOException - if an I/O error occurs
        NullPointerException - if cb is null
        ReadOnlyBufferException - if cb is a read only buffer
