What are inheritance and access modifiers in Java?

Inheritance in Java allows a class to inherit properties and methods from another class. Access modifiers control the visibility of classes, methods, and variables.

Can you explain the different types of access modifiers?

Sure! The main access modifiers in Java are public, private, protected, and default. Public members are accessible from anywhere, private members are accessible only within the same class, protected members are accessible within the same package and subclasses, and default members are accessible only within the same package.

How does inheritance work with access modifiers?

When a subclass inherits from a superclass, it can access the public and protected members of the superclass. However, it cannot access private members directly.

Can you give an example of inheritance with access modifiers?

Certainly! If you have a class Animal with a protected method makeSound(), a subclass Dog can inherit and use that method, but a class outside the package cannot access it.
