The hashCode method is an inbuilt method that returns the integer hashed value of the input value . Here are a few key concepts to remember: Multiple invocations of the hashCode must return the same integer value within the execution of a program unless the Object used within the equals method changes.

Read moreCan objects be equal to each other?
Since computing an object’s equality is a time-consuming task, Java also provides a quick way of determining if an object is equal or not, using hashCode() . This returns a small number based on the object’s internal datastructure; if two objects have different hash codes, then they cannot be equal to each other .
Read moreWhat is the use of equals method of Object class?
The equals method for class Object implements the most discriminating possible equivalence relation on objects ; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
