Class members declared as protected can be used only by the following: Friends of the class that originally declared these members.

Which feature is supported by Java but not by C language?

Java has support for the only call by value. The C programming language is used for both system programming as well as Application programming.

Why do we use protected?

So if we want data members to be accessible to only derived classes and not privately or publicly accessible, then we can use protected. – Protected is similar to private. – It makes class member inaccessible outside the class, but the members can be accessed by any subclass of that class.

Can we make class protected in Java?

No, we cannot declare a top-level class as private or protected. It can be either public or default (no modifier).

What is difference between protected and default in Java?

The protected specifier allows access by all subclasses of the class in question, whatever package they reside in, as well as to other code in the same package. The default specifier allows access by other code in the same package, but not by code that is in subclasses residing in different packages.

What is the difference between protected and private?

The class members declared as private can be accessed only by the functions inside the class. The class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass(derived class) of that class.

What is difference between protected and public?

Difference between Public and Protected The data members and member functions declared public can be accessed by other classes too. The class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass(derived class) of that class.

What is the difference between protected and private in Java?

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.

Why is Java better than C?

C is a procedural, low level, and compiled language. Java is an object-oriented, high level, and interpreted language. Java uses objects, while C uses functions. Java is easier to learn and use because it’s high level, while C can do more and perform faster because it’s closer to machine code.

What is main difference between C and Java?

Can a base class be protected in Java?

Unlike C++, Java doesn’t provide an inheritance specifier like public, protected or private. Therefore, we cannot change the protection level of members of base class in Java, if some data member is public or protected in base class then it remains public or protected in derived class.

What’s the difference between private and protected in Java?

private hides from other classes within the package. public exposes to classes outside the package. protected is a version of public restricted only to subclasses. @Tennenrishin — No ; contrary to C++, in Java protected makes the method also accessible from the whole package.

What’s the purpose of a protected keyword in Java?

The main purpose of protected keyword is to have the method or variable can be inherited from sub classes. Related keyword: public and private. See all keywords in Java.
