![]() For example, a setter method might be used to ensure that a person’s age is set to a valid value between 0 and 120. In addition, setter methods are often used to enforce certain constraints or validation checks on the values being set for an attribute. This allows other classes to access the attributes of an object through these methods. It is important to note that getter and setter methods should be declared as public. Getter and setter in java are an example of how this can be achieved in Java.Ī getter method, also known as an accessor method, is used to retrieve the value of an object’s attribute.Ī setter method, also known as a mutator method, is used to set the value of an object’s attribute. This helps to promote information hiding, which is an important aspect of OOP. Encapsulation is the practice of hiding an object’s internal details and only exposing its public interface. In Object Oriented Programming (OOP), encapsulation is one of the fundamental concepts. They are also referred to as accessor methods and mutator methods. Getter and Setter in Java are methods used to access and set the values of an object’s attributes, respectively. We use getter and setter in java to access the data that is hidden by encapsulation. This makes it easier to change the implementation without affecting the code that uses the thing. It also helps maintain the integrity of an object’s state by allowing changes to be made to the object through methods only. Encapsulation provides data security by preventing unauthorized access to data members and methods. It is used to hide the implementation details from the user and expose only the necessary information. ![]() Encapsulation in Java is a concept in object-oriented programming that refers to the bundling of data with the methods that operate on that data within an object. Encapsulation is one of the four pillars of object-oriented programming. Getter and Setter in java are part of the encapsulation. ![]()
