A class is a template or blueprint from which objects are created. So, an object is the instance of a class.
Object contains its own copy of each instance variable defined by the class.
To access these variables use the dot (.) operator.
The dot operator links the name of the object with the name of an instance variable.

Understanding Objects in Java
In Java, objects play a crucial role in the object-oriented programming paradigm. Let's break down the characteristics of objects that make option 'D' the correct answer.
1. A Runtime Entity
- Objects exist during the execution of a program.
- When a class is instantiated, it creates an object in memory, making it a runtime entity.
- This means objects can be created, modified, and destroyed while the application is running.
2. An Entity with State and Behavior
- Objects encapsulate state (attributes) and behavior (methods).
- The state of an object is represented by its instance variables, which hold data.
- The behavior is defined by methods that operate on the object's state, allowing interaction and functionality.
3. An Instance of a Class
- In Java, a class acts as a blueprint for creating objects.
- When a class is instantiated, it creates an object, meaning every object is an instance of a class.
- This relationship between classes and objects is fundamental to the object-oriented approach.
Conclusion
Each of these points confirms that objects in Java are indeed:
- Runtime entities,
- Entities with state and behavior,
- Instances of classes.
Thus, combining all these characteristics leads to the conclusion that the correct answer is option 'D': All of the above. Understanding these concepts is essential for effective programming in Java and leveraging the power of object-oriented design.
