    Getters and setters are methods used in object-oriented programming to access and modify the values of private variables. They provide a way to encapsulate the data and ensure that it is accessed and modified in a controlled manner.

    Definition and Purpose

    Getters (also known as accessors) are methods that return the value of a private variable. They are typically named with the prefix "get" followed by the variable name with the first letter capitalized. For example, if the variable name is name, the getter method would be getName().

    Setters (also known as mutators) are methods that set or update the value of a private variable. They are typically named with the prefix "set" followed by the variable name with the first letter capitalized. For example, if the variable name is name, the setter method would be setName(String newName).

    Example in Java

    Here is an example of a class with a private variable and its corresponding getter and setter methods:
