Java is an object-oriented programming language. This means that the fundamental elements of Java are objects and classes. A class is a blueprint that defines the nature of a particular type of objects, while objects are instances of these blueprints. In this article, we will delve into defining, using, and understanding classes and objects in Java.
Defining Classes
In Java, to define a class, we use the class
keyword. A class may contain fields (variables) and methods. Here's a simple example:
public class Car {
// Fields
String brand;
String model;
int year;
// Methods
void drive() {
System.out.println("The car is being driven.");
}
void brake() {
System.out.println("The car is braking.");
}
}
In the example above, we have defined a class named Car
. This class has three fields (brand
, model
, year
) and two methods (drive
, brake
).
Creating Objects
To create an object using a class, we use the new
keyword. Here's an example of creating a Car
object:
public class Main {
public static void main(String[] args) {
// Creating an object of Car class
Car myCar = new Car();
// Accessing and assigning values to the object's fields
myCar.brand…
