What are the variuos Access Specifiers available in Java?



Posted By: Avi Date: 9 November 2009 06:29:07 AM
 Answer:

Java offers following four access specifiers:

1) public:
public classes, methods, and fields can be accessed from everywhere.

2) protected:
protected methods and fields can only be accessed within the same class to which the methods and fields belong, within its subclasses, and within classes of the same package.

3) default(no specifier):
If you do not set access to specific level, then such a class, method, or field will be accessible from inside the same package to which the class, method, or field belongs, but not from outside this package.

4) private:
private methods and fields can only be accessed within the same class to which the methods and fields belong. private methods and fields are not visible within subclasses and are not inherited by subclasses.

Java has four different access specifiers: public private package and protected !!!

private : The most restrictive of the access specifiers is private. If a variable [or a method] is declared private then it can only be accessed by methods in that class.

public : The least restrictive of the access specifiers is public. If a method has public in front of it then any object of that class can be told to perform that action.

package : Every class that is in the same package has access to the fields and methods in your class.

protected : If you have a variable or method in your class that you don't want clients of your class directly accessing declare it protected.
