What is the purpose of the class in Java?

In Java, the role of a class is to serve as a template or blueprint for defining objects. It contains the definitions of the object’s attributes and methods, and can be used to instantiate multiple specific objects. Classes are the fundamental unit of object-oriented programming, used to encapsulate data and behavior, enabling code reusability and modularization. Through classes, multiple objects with the same attributes and behaviors can be created, and more complex object relationships and data structures can be achieved through the class inheritance mechanism.
