Java Encapsulation

Encapsulation is one of the fundamental principles of Object-Oriented Programming (OOP). It is the process of wrapping data (fields) and methods (behavior) together into a single unit (class) and restricting direct access to them. Instead, access is provided through public methods, known as getters and setters.

In Java, encapsulation is implemented by:

Declaring fields as private.
Providing public getter and setter methods to access and update the values of the fields.

Example

class Human{

private int age; // private = restricted access

// Getter

public int getAge(){

return age;

}

// Setter

public void SetAge(int a){

age=a;

}

public class Main {

public static void main(String[] args){

Human obj=new Human();

obj.SetAge(30);

System.out.println("Name : "+obj.getAge());

}
