Implementation of a Cyclic Redundancy Check in Java

CRC code is an error detection code used usually on digital networks to detect random changes (errors) data sent. For each block of data consisting of k bits, the transmitter creates a sequence of n bits such that the total sequence of k + n bits that turns out to be exactly divisible by a predetermined number P. In then the receiver receives the sequence of k + n bits together with P. If dividing the sequence by P does not occur then the message has reach to deteriorate.
