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.

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. A is a template or a prototype from

public void drive() { System.out.println("The car is moving."); } Use code with caution. Copied to clipboard 5. Constructors: Initializing Objects Classes and objects form the heart of Java

An is a basic unit of Object-Oriented Programming and represents a real-life entity. When a class is defined, no memory is allocated until an object of that class is created. Instantiation: Objects are created using the new keyword. Master these four pillars, and you have the

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

It contains fields (variables) to store the state and methods to define behavior.
