What is a setter in programming?

Getters and Setters play an important role in retrieving and updating the value of a variable outside the encapsulating class. A setter updates the value of a variable , while a getter reads the value of a variable.

In computer science, a mutator method is a method used to control changes to a variable . They are also widely known as setter methods. Often a setter is accompanied by a getter (together also known as accessors), which returns the value of the private member variable.

Getter and setter methods are the class methods used to manipulate the data of the class fields . Getter is used to read or get the data of the class field whereas setter is used to set the data of the class field to some variable.31 Eki 2021
