Java Modifiers

This lesson is part of Java · All levels

Summary

Modifiers are divided into two groups: access modifiers (public, protected, private, default) and non-access modifiers (static, final, abstract, etc.). Access modifiers determine from where a member of a class can be accessed, whereas non-access modifiers set additional behaviors such as belonging to a class or not to be modified. Choosing the right modifier is key to a neat class design.

Key points

Public can be accessed from anywhere, private only from within the class itself.
Protected can be accessed in the same package and class derivative
Without the access modifier means the package-private, only in the same package
Non-access modifiers such as static and final regulate how members work
