What are access modifiers in Java?

Access modifiers in Java are keywords that set the accessibility of classes, methods, and variables. The main ones are public, private, protected, and default.

Can you explain encapsulation?

Encapsulation is a fundamental concept in OOP that restricts direct access to some of an object's components. It helps to protect the integrity of the object's data.

How do access modifiers relate to encapsulation?

Access modifiers are used to implement encapsulation by controlling access to the class members. For example, using private access restricts access to the class itself.

Can you give an example of encapsulation in Java?

Sure! For instance, you can have a class with private variables and public getter/setter methods to access those variables, ensuring controlled access.
