Techopedia explains Static Field
A static field or class variable is useful in certain programming languages and code situations to assign a particular variable (representing a common characteristic) to all instances of a class, either as a fixed value, or one that could change in the future. The key to this type of identifier is that if the change happens, it will be applied equally to all instances of the class.
