# Access Modifiers

<br>

<br>

### Access Modifiers

<br>

#### Public

: Allows all access

#### Protected

: Allows access only to objects in the same package (folder) and objects in an inheritance relationship

#### Default

: Allows access only to objects in the same package (folder)   => same package

#### Private

: Allows access only within the current object   => same class

<br><br>

### Access Restriction

- By using access restriction, data (instance variables) is blocked from direct external access, and the operations that can modify or act on the data are kept internal.
  - This way, the outside cannot know what changes are happening internally, and can only receive results through methods

    => Information hiding is possible
