When should I use public access modifier in Java?

Can you explain when to use the public access modifier in Java?

Sure! The public access modifier in Java is used when you want to allow access to a class, method, or variable from any other class.

Are there any specific scenarios where I should definitely use public?

Yes, you should use public when you want to expose functionality that needs to be accessible from other classes, like utility methods.

What are the downsides of using public too much?

Using public too much can lead to tight coupling between classes, making your code harder to maintain and test.

How does public compare to private and protected?

Public allows access from anywhere, private restricts access to the same class, and protected allows access to subclasses and classes in the same package.
