What does the term "Class" refer to in object-oriented programming?

The term "Class" in object-oriented programming refers primarily to the concept of an "object blueprint." A class serves as a template from which individual objects are created. It defines the properties (attributes) and behaviors (methods) that the objects created from the class will have. For instance, if you have a class called "Car," it would outline the characteristics like color, make, model, and the behaviors such as drive, stop, or honk.

This organization helps in structuring code in a way that is modular, reusable, and easily manageable. By creating multiple objects from a single class, developers can generate numerous instances that share common functionality while allowing individual customization, thus enabling efficient code management and reducing redundancy.

Other options offered do not accurately represent the concept of a class. The functionality of code refers more to how the code performs tasks rather than the structural idea of a class. Similarly, a database query pertains to data retrieval from a database and does not connect to class definition in programming. Lastly, a user interface component deals with elements seen on a GUI, which is separate from the underlying structure that a class provides.
