      • 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.

        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
