Your question: Can protected be used in different package?

9 Answers. protected allows access from subclasses and from other classes in the same package. That’s why any Derived class instance can access the protected method in Base .

Can we use protected in another package?

The protected access modifier is accessible within the package. However, it can also accessible outside the package but through inheritance only. We can’t assign protected to outer class and interface. If you make any constructor protected, you cannot create the instance of that class from outside the package.

How do I access protected variables from different packages?

Basically, the protected keyword is an access modifier for method and variable of a class.

When a method or a variable is marked as protected, it can be accessed from:

  1. Within the enclosing class.
  2. Other classes in the same package as the enclosing class.
  3. Sub classes, regardless of packages.

How can a protected method be used in another class?

Protecting a constructor prevents the users from creating the instance of the class, outside the package. During overriding, when a variable or method is protected, it can be overridden to other subclass using either a public or protected modifier only. Outer class and interface cannot be protected.

Is protected the same as package private?

The private modifier specifies that the member can only be accessed in its own class. The protected modifier specifies that the member can only be accessed within its own package (as with package-private) and, in addition, by a subclass of its class in another package.

Can we override static method?

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Are protected methods Final?

1) Private methods are final. 2) Protected members are accessible within a package and inherited classes outside the package. 3) Protected methods are final. 4) We cannot override private methods.

What are protected methods?

A protected method is like a private method in that it can only be invoked from within the implementation of a class or its subclasses. It differs from a private method in that it may be explicitly invoked on any instance of the class, and it is not restricted to implicit invocation on self .

Can a class declared as private be accessed outside it’s package?

Can a class declared as private be accessed outside it’s package? Not possible. … The protected access modifier cannot be applied to class and interfaces. Methods, fields can be declared protected, however methods and fields in a interface cannot be declared protected.

Can we override protected method as public?

Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.

Can we inherit private method in Java?

Yes. A java private member cannot be inherited as it is available only to the declared java class. Since the private members cannot be inherited, there is no place for discussion on java runtime overloading or java overriding (polymorphism) features.

What are the protected members inheritance?

Protected Inheritance − When deriving from a protected base class, public and protected members of the base class become protected members of the derived class. Private Inheritance − When deriving from a private base class, public and protected members of the base class become private members of the derived class.
