In Java, what is the relationship between a class and an object?

• A. An object is a blueprint for creating a class.
• B. An instance created from a class blueprint.
• C. A class is a blueprint for creating objects.
• D. Objects and classes are the same.

Answer: (C)

In Java, a class serves as a blueprint for creating objects. It defines the structure (fields) and behavior (methods) that objects created from it will have. An object is a concrete instance of that class, created at runtime (for example, using new). Each object has its own state (its fields) while sharing the same methods defined by the class. There can be many objects created from a single class, all of which follow the same template but hold different data. So the relationship is that the class provides the template, and objects are the actual instances produced from that template. The idea that an object is the blueprint, or that objects and classes are the same, doesn’t fit the relationship.
