    - #### writeByte

          public void writeByte(byte b)

      Description copied from class: `DataOutput`
      Writes a single byte.

      The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.

      Specified by:
        `writeByte` in class `DataOutput`
      See Also:
        `DataInput.readByte()`

    - #### writeBytes

          public void writeBytes(byte[] b,
                                 int offset,
                                 int length)

      Description copied from class: `DataOutput`
      Writes an array of bytes.
      Specified by:
        `writeBytes` in class `DataOutput`
      Parameters:
        `b` - the bytes to write
        `offset` - the offset in the byte array
        `length` - the number of bytes to write
      See Also:
        `DataInput.readBytes(byte[],int,int)`
