What is class in java programming with example

What is class in java programming with example


A class in Java programming is a blueprint or template that specifies the properties and methods that can be applied to an object. In essence, it is a user-defined data type that combines information about data and action into a single entity.


A class defines the traits and actions that apply to all of its members' objects. The behaviours are defined as methods, while the qualities are defined as class variables or fields. A class can also take on traits and actions from other classes, which can lessen code duplication and enhance code structure.



A "Car" class may be created, for instance, if you were making a programme to simulate cars. This class would define a car's attributes, such as its make, model, and year, as well as methods for starting the engine, accelerating, and stopping. The Car class could then be used to generate instances, each of which would have a unique set of property values and be capable of executing the same set of operations.


What is class in Java explain?

A class in Java is a logical template to create objects that share common properties and methods. Hence, all objects in a given class will have the same methods or properties. For example: in the real world, a specific cat is an object of the “cats” class.



here example 


public class Car {

    // class variables or fields

    String make;

    String model;

    int year;


    // constructor

    public Car(String make, String model, int year) {

        this.make = make;

        this.model = model;

        this.year = year;

    }


    // methods

    public void startEngine() {

        System.out.println("The " + make + " " + model + " is starting.");

    }


    public void accelerate() {

        System.out.println("The " + make + " " + model + " is accelerating.");

    }


    public void stop() {

        System.out.println("The " + make + " " + model + " is stopping.");

    }

}
