What is the main role of the Object class in Java programming?

In Java, the Object class is the root class of the entire class hierarchy. This means that all classes implicitly inherit from Object.

Main roles of the Object class:

• Defines basic methods available to all objects, such as:

  • toString() — returns a string representation of the object.
  • equals(Object obj) — checks for object equality.
  • hashCode() — returns the hash code of the object.
  • clone() — creates a copy of the object (supported by the Cloneable interface).
  • finalize() — called before garbage collection (deprecated method).

• Provides a unified interface for all objects, allowing them to be used in collections and other data structures.

Thus, the Object class sets the basic behavior and contract for all objects in Java.
