Know About Java Modifiers

As we all know java has below modifiers :

• public
• private
• protected
• no modifiers (package private)

Class level Modifiers (only class) :

• If a class is ‘public’, then it CAN be accessed from ANYWHERE.
• If a class has ‘no modifer’, then it CAN ONLY be accessed from ‘same package’.

Member Level Modifiers (variables & methods):

• public and no modifier – the same way as used in class level.
• private – members CAN ONLY access.
• protected – CAN be accessed from ‘same package’ and a subclass existing in any package can access.

Please see below table :

Access Modifiers	Same Class	Same Package	Subclass	Other packages
public	Y	Y	Y	Y
protected	Y	Y	Y	N
no access modifier	Y	Y	N	N
private	Y	N	N	N
