"Java Basics" "Public, default, protected, private, and other modifiers"

has been the concept of these modifiers is not very clear, while the intern assessment just ended empty time to study.

1. Modifiers that can modify member variables and member methods have three plus one default. Their scope uses the following:

Scope Current class same package descendant class other package

Public√√√√

Protected√√√x

FRIENDLY√√XX (default)

Private√xxx

2. Modifiers that can modify the class name are only public, and default. The scope is inferred from the above that public can apply to all packages, and the default can only be used in their own packages.
