        public Heap​(int limit)
        Create a new heap buffer with a maximum storage limit.
        Parameters:
        limit - maximum number of bytes that can be stored in this buffer; also used as the estimated size. Storing beyond this many will cause an IOException to be thrown during write.

            int limit)
        Create a new heap buffer with a maximum storage limit.
        Parameters:
