In this tutorial we will discuss about Encapsulation in Java. Encapsulation is the mechanism for restricting access to an object’s components. It aims for high maintenance and handling of the application’s code. Also, the encapsulation mechanism protects the members of a class from external acces...
Encapsulation Explanation With Example In JAVA: Now we will explain the concept of Encapsulation with example. Example 1:In the below example, we will set two fields as private name and email in class UserDetails. So these fields can only be access within this class and no outside class can...
In above example all the three variables (or data fields) are private(see:Access Modifiers in Java) which cannot be accessed directly. These fields can be accessed via public methods only. VariablesempName,ssnandempAgeare made hidden data fields using encapsulation technique of OOPs. Advantages of...
In Java, encapsulation helps us to keep related fields and methods together, which makes our code cleaner and easy to read. It helps to control the values of our data fields. For example, class Person { private int age; public void setAge(int age) { if (age >= 0) { this.age =...
Hence, Encapsulation in Java language means binding the data (variables) with the code(methods – setters and getters). In this tutorial, we shall learn the intuition and realization of encapsulation in Java language with example programs. The below diagram gives an idea about Encapsulation in ...

Provide public setter and getter methods to modify and view the variables values.Below given is an example that demonstrates how to achieve Encapsulation in Java:/* File name : EncapTest.java */public class EncapTest{ private String name; private String idNum; private int age; public int ...
Example of Encapsulation in Java classPerson{privateString name;privateintage;// Getter method for namepublicStringgetName(){returnname;}// Setter method for namepublicvoidsetName(String name){this.name=name;}// Getter method for agepublicintgetAge(){returnage;}// Setter method for age with ...
Encapsulationin Java is a mechanism of wrapping the data (variables) and code acting on the data (methods) together as as single unit. In encapsulation the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class, therefore ...
Example: This example demonstrates the member type encapsulation where the student roll no is considered, and then the variable is manipulated for making the member variable encapsulation successfully executed, as shown in the output below. Code: ...
