تعیین سطح دسترسی در جاوا

• Access specified specified the accessibility of the members.
• access specified can be used before a method, constructor, variable, constant, class and other structures.
• java can support  4 types of access specifides: 1-public 2-private 3-protected 4-default
• the public describes the accessibility as global. that means any one can use public members.
• private accessibility is only within the class. the same class members can be access private members.
• default: if we will not mention any access specified, as public, private or protected then java compiler identify the access specified as a default. there is no keyword for default accessified. the default member is available/accessible only within the package and outside the package it is private. it means inside package it is public else it is private.
• protected is same as Default. but can be accessible through sub class out side of the package.
• we can create private, for the inner class not for the class.
