Final answer:
A static field in computer programming is also known as a class field, which is associated with the class as a whole rather than with any individual instance. It is shared across all instances of that class and is important for data that should be consistent across all objects of the class.
Step-by-step explanation:
A static field, in the context of computer programming, specifically object-oriented programming, is known as D) A class field. A static field is one that is associated with a class rather than any individual instance of that class. In other words, a static field is shared across all instances of the class. This concept is important for understanding how to manage data that should be consistent and accessible by all objects created from a particular class.
For example, if we consider a class 'Calculator,' a static field could be a calculator version that needs to be the same for all calculator instances. Such a static field belongs to the class itself, not to any specific object or instance of the class.
The other options, A) An object field and C) An instance field, are fields that belong to an individual object and each object can have its own value for these fields. B) An empty field is not a term commonly used in object-oriented programming.
