Java Hashcode() (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In the Java programming language, every class must provide a hashCode() method which digests the data stored in an instance of the class into a single hash value. This hash is used by other code when storing or manipulating the instance - the values are intended to be evenly distributed for varied inputs in order to avoid clustering. This property is important to the performance of hash tables and other data structures that store objects in groups based on their computed hash values.
