What are access modifiers in programming?

Access modifiers are keywords used in object-oriented programming to set the visibility of classes, methods, and variables.

Can you explain the different types of access modifiers?

Sure! The main types are public, private, and protected. Public members are accessible from anywhere, private members are only accessible within the class, and protected members can be accessed in the class and its subclasses.

Why would I use private or protected instead of public?

Using private or protected helps encapsulate your data, protecting it from unintended interference and promoting better code maintenance.

Can you give an example of each access modifier?

Certainly! In Java, a public method can be accessed from any class, a private method can only be accessed within its own class, and a protected method can be accessed in its own class and subclasses.
