Getters and Setters

Getters and setters are accessor methods in object-oriented programming that provide controlled access to an object's private fields. A getter retrieves the value of a property, while a setter modifies it, often including validation or side effects. They are fundamental to encapsulation, allowing classes to hide internal state while exposing a public interface.

Also known as: Accessors, Property Methods, Getter/Setter Methods, Accessor Methods, Property Getters and Setters

Why learn Getters and Setters?

Developers should use getters and setters to enforce data integrity, add logic during property access (like validation or logging), and maintain backward compatibility when internal implementations change. They are essential in languages like Java, C#, and Python for implementing properties, and are widely used in frameworks that rely on data binding, such as in frontend libraries like React or Vue.js.
