What are the different access modifiers in Java?

What are the different access modifiers in Java?

In Java, there are four main access modifiers: public, private, protected, and default (package-private). Each controls the visibility of classes, methods, and variables.

Can you explain the difference between public and private access modifiers?

Sure! A public access modifier allows the class, method, or variable to be accessible from any other class. In contrast, a private access modifier restricts access to the defining class only.

What about the protected modifier?

The protected modifier allows access to the class, method, or variable within its own package and by subclasses, even if they are in different packages.

What happens if I don't specify an access modifier?

If no access modifier is specified, the default access level is used, which means the class, method, or variable is accessible only within its own package.
