hashCode.Object: Gets a hash code for the Object

Description

Gets a hash code for the Object. This makes it possible to put any Object in a hash table. The hash code returned must: 1) be consistent, i.e. hashCode(obj) should return the same value on multiple invocations as long as nothing has changed. 2) tell same same thing as equals(), if equals(o1,o2) is TRUE, then hashCode(o1) == hashCode(o2) should also be TRUE. Note that if equals(o1,o2) is FALSE, hashCode(o1) hashCode(o2) may be either equal or non-equal. By default, the method returns the internal memory address where the Object is located.
