To interact with these attributes, we've created public getter and setter methods. We've made the 'name' and 'age' attributes private, meaning they can only be accessed within the 'Person' class.

Let's update our 'Person' class to demonstrate encapsulation: By default, if no access modifier is specified, the attribute or method is accessible within the same package. In Java, we achieve encapsulation using access modifiers (public, private, and protected). Encapsulation also involves hiding the internal state of an object from the outside world and only exposing the necessary parts through public methods. Hello, my name is Jane Doe and I am 30 years old.Įncapsulation is one of the four OOP principles, and it refers to the bundling of data (attributes) and methods that operate on that data within a single unit (class). We can create multiple objects from the same class, each with its own set of attributes: Hello, my name is John Doe and I am 25 years old. Now that we have an object, we can assign values to its attributes and call its methods: To create a new object, we use the 'new' keyword followed by the class name and parentheses. An object is an instance of a class, and it contains the attributes and methods defined in the class. Now that we have a class, we can create objects from it.

The 'talk' method simply prints out a message containing the person's name and age. In this example, we have a class called 'Person' with two attributes (name and age) and one method (talk). ('Hello, my name is ' + name + ' and I am ' + age + ' years old.') Let's create a simple class called 'Person' with some attributes and methods: The general syntax for declaring a class is as follows: Classes define the attributes and methods of an object. Java ClassesĪ class in Java is a blueprint for creating objects. This tutorial will primarily focus on classes and objects, which are the foundation of encapsulation and inheritance in Java. These objects are instances of classes, which are essentially blueprints for creating objects. In OOP, the focus is on creating objects that contain both data (attributes) and methods (functions) that interact with the data. Object-Oriented Programming (OOP) Overview By the end of this tutorial, you should have a solid understanding of the fundamentals of Java OOP. This tutorial will provide an in-depth introduction to Java object-oriented programming, focusing on classes and objects.

Java, as a language, was designed with OOP in mind, making it a powerful tool for software developers. One of the most popular programming paradigms is Object-Oriented Programming (OOP).
