Question
What is the importance of public, private, protected, default modifiers both singly and in combination and explain how declared items qualified by these modifiers are effected by the package relationships ?
Answers
Public : Field is visible everywhere whereas Public class is visible in other packages (class must be public too) Private : Private variables or methods may be used only by an instance of the same class that declares the variable or method, A private feature may only be accessed by the class that owns the feature.
Protected : Is available to all classes and sub classes in the same package of the class that owns the protected feature.This access is provided even to subclasses that reside in a different package from the class that owns the protected feature.
Default :It is visible to all within a particular package. without any access modifier (ie, public private or protected)   Your Comment
