I am a java beginner. This time, I will output about access modifiers.

Q1: What is an access modifier?

・ Determines the accessible range for methods and variables. [Japanese translation] ** access **: Access, approach, entry and exit

Access scope of specific access modifiers (4)

① ** public **: Can be accessed from anywhere

② ** Modifier **: Only in the same package

③ ** private **: Only in the same class

④ ** protected **: Within the same package class or subclass

What is a subclass? : A class that inherits the fields and methods of the parent class (superclass) by inheritance. Subclass details

When to use access modifiers

There is no particular pattern because public and unqualified patterns are free. ** private ** and ** protected ** are unique.

・ Private: Used in places where access from the outside must be absolutely prevented (Places where personal information is acquired, etc.) It can only be accessed from the specified method.

・ Protect: Can only be used for variables or methods
