Methods are called on objects using the dot ( . ) operator.

While not explicitly in the title, these concepts are inseparable from classes. Java uses access modifiers like public , private , and protected to control visibility. ensures that the internal state of an object is hidden from the outside, accessible only through public methods (getters and setters). 7. Conclusion Methods are called on objects using the dot (

Classes and objects form the heart of Java. Classes provide the structure, while objects provide the realization of that structure. Methods define how these objects interact, and constructors ensure they start their lifecycle in a valid state. Master these four pillars, and you have the foundation to explore more complex topics like inheritance and polymorphism. Java uses access modifiers like public , private

Used to provide specific values to object fields at the time of creation. Conclusion Classes and objects form the heart of Java

A is a template or a prototype from which objects are created. It defines the properties (fields) and behaviors (methods) that all objects of that type will share. Declaration: Uses the class keyword.

Java is a high-level, class-based, object-oriented programming language. The fundamental philosophy of Java is to represent real-world entities as "Objects." To create these objects, developers use "Classes" as blueprints. Understanding the relationship between these components is essential for writing efficient, modular, and reusable code. 2.
