When a byte, long etc. has been written into the Buffer the position is advanced to point to the next cell in the buffer to insert data into. Position can maximally become capacity - 1 . When you read data from a Buffer you also do so from a given position.
WebJun 29, 2024 · To make sure that we start reading from the right place in the buffer, we'll use Buffer.flip() to set our ByteBuffer‘s current position to zero and its limit to the last byte that was written by the SocketChannel. We'll then save the buffer contents using our storeBufferContents method, which we'll look at later.
