Objects: Instances of Classes
Explore the core concept of object-oriented programming by understanding how objects are instances of classes in Java. Learn about class blueprints, object creation using constructors with the new keyword, and the relationship between class attributes and methods. This lesson lays the foundation for effective use of classes and objects in your Java coding journey.
We'll cover the following...
It’s time to get an overview of object-oriented programming.
📌 Note: We’ll get into further detail in unit 5.
The class is a blueprint, or formal implementation of a data type, where objects are instances of such a class. Essentially, an object is a variable of the type defined by a class.
We can instantiate multiple objects of a class. For example, we can create as many String type variables as we want.
