Access specifiers

Java have four access specifiers.

• public :
• The keyword which is used a access specifier whose data can be accessible in same class, other class, other program, other folder, other colon and even other machine.
• Java follows client-server architecture, so main() method should be public.
• private :
• The stronger access specified which restricts the data to be come out of class.
• Private data can not be accessible even through it's class object.
• protected :
• The partial public and partial private access specifier.
• It follows public property as the data can be come out of the class but only in inheritance.
• It private property can not be accessible through class object.
• default :
• It is not keyword.
• It works same as public up-to one working folder.
• Otherwise it becomes private.
