The hashCode() method is used in Java to generate a unique integer value representing an object's identity. It is often overridden in classes when custom equality comparisons need to be made.
Think of the hashCode() method as a fingerprint scanner. Just like each person has a unique fingerprint, objects in Java have a unique hash code that can be used to identify them.
equals(): The equals() method is used to compare two objects for equality based on their content or attributes.
Object class: The Object class is the root class in Java from which all other classes are derived. It provides basic methods such as hashCode(), equals(), and toString().
Hash table: A hash table is a data structure that uses hash codes to store and retrieve values efficiently. It is often used for fast lookup operations.
