The Anatomy of a Java Class


A Java class acts as a blueprint from which objects can be created. A class specifies the variables and methods that define the object's behavior. This is analogous to a real blueprint, which specifies the structure and function of a house. In this context, the blueprint is a class, and a house is an object based on the blueprint class.
