Course Description

In this course, you will learn about access modifiers that can be used to tag member variables and member functions inside Java classes to regulate how these can be accessed from different contexts. Participants begin by examining the properties of public, private, and protected access modifiers. These properties govern how classes, member functions, and member variables can be accessed within the same class, outside the same class but within the same package, and in entirely different packages. This leads into an examination of cross-package access and how access works from one package into another. You will then learn about the semantics of protected members, and the use of the protected access modifier. Next, explore the cross-package access of protected members, which enables you to use the protected keyword across packages. As the course concludes, you will learn about the semantics of using default access modifiers both inside and outside the same package.
