    First of all, Object class is the super/base/parent class of every class including user-defined classes.

    So even if we don’t mention it explicitly, the user-defined classes extends Object class by default.

    Morevoer, Object class implements a set of methods and variables which are common to all the objects being created in the application. This is the main reason why we have Object class as a base class for all the other classes.

    For eg:

    hashCode() – this method creates a unique identity for each of the object being created in JVM.
