Class / Object in OOPs

I am Naimish Trivedi, I have a far experience in native and hybrid programming. I have presented the programming concept here in a simple and easy way from my experience. This will be very useful for beginner Devs and Students.

We have seen ladder of OOPs concept in previous article now in this article, we will learn about class and object in oops.

What is a class in Java

• A class is a blueprint or template for creating objects.
• It defines the attributes (fields/variables) and behaviors (methods/functions) that objects of that class will have.
• Classes encapsulate data for the objects, along with methods to operate on that data.
• In Java, a class is declared using the class keyword followed by the class name.

Example of a simple class in Java:

What is an object in Java

• An object is an instance of a class. It's a real-world entity that has a state and behavior.
• Objects are created from classes using the new keyword, which invokes a constructor to initialize the object.
• Each object has its own set of attributes (fields) and can perform actions (methods) defined in its class.

Example of creating and using objects in Java:

In this example, Person is a class that represents person. We create two person objects (object1 and object2) using the new keyword. Then, we access their fields and call their methods.

That's it for now.

Thanks,

Stay tuned for another chapter on OOPs Concept.
