These methods provide write-only access to the object's state. By using mutator methods, you can ensure that the object's state is modified only through a controlled interface. Let's take a look at an example to understand the concept of accessor and mutator methods in Java.

Also known as setter methods, mutators are responsible for modifying the state of an object by updating its instance variables. In this section, we will explore the concept of mutator methods in Java, their significance, and how they contribute to creating robust and encapsulated classes.
