hashCode() the implementation of the General method, equal objects, their hash code must be equal.Back to Tophashcode () method detailedhashCode()method returns a hash code value to the object. This method is used for hash tables, such as HashMap.The nature of this is: During the execution of a Java application, if the information provided by an object to equa
