In Java, classes and objects form the foundation of Object-Oriented Programming (OOP). They help model real-world entities and organize code in a structured way.
A class is a blueprint used to create objects that share common properties and behavior.
An object is an instance of a class. It represents a specific entity created from the class template.
For Example, Dog is a class, Tommy is an object of that class.
Java class
A class is a blueprint that defines data and behavior for objects. It groups related fields and methods in a single unit. Memory for its members is allocated only when an object is created.
Acts as a template to create objects with shared structure.
Does not occupy memory for fields until instantiation
Can contain fields, methods, constructors, nested classes and interfaces.
