Classes And Objects - Defining A Class

Classes and objects are fundamental concepts in Java and object-oriented programming (OOP). A class is a blueprint for creating objects. Objects are instances of the class, created based on the blueprint. Classes define the variables (fields) and functions (methods) that the objects created from the class will have.

Now, our Dog class has 2 fields and 1 method. But, how do we use this?
