What is the role of the Object class in Java and why is it provided in the programming language?

The Object class in Java is the root class for all classes in the language. This means that every class implicitly inherits from Object unless explicitly specified otherwise. It provides basic methods such as:

• toString() — returns a string representation of the object;
• equals(Object obj) — compares objects for equality;
• hashCode() — returns the hash code of the object;
• clone() — creates a copy of the object;
• getClass() — returns the Class object describing the class of the object.

The role of Object is to provide a common set of basic operations for all objects, which simplifies working with them and enables polymorphism.
