What are the different types of access specifiers in C++?
In C++, there are three access specifiers: public - members are accessible from outside the class. private - members cannot be accessed (or viewed) from outside the class. protected - members cannot be accessed from outside the class, however, they can be accessed in inherited classes. You will learn more about Inheritance later.
What is the use of access specifier in Java?
The job of access specifier is to specify the scope of a variable (data member), function (method), constructor or any class. We can also call these prefixes as access modifiers. Large programs contain a large number of classes and methods. Many of the methods are reused in the program.
How many access modifiers can a class or interface have?
The access modifiers are listed according to their restrictiveness order. But, the classes and interfaces themselves can have only two access modifiers when declared outside any other class. Note: Nested interfaces and classes can have all access modifiers. Note: We cannot declare class/interface with private or protected access modifiers.
What is the difference between protected and member access specifier?
Members of the same class as well as members of a different class within the same package can access the default members. Even the subclasses cannot view or access the default members of its parent class. Thus this access specifier is more restrictive than protected.
Overview
In this article, we will learn about different types of access specifiers available in Java. In other words, we will discuss the scope of visibility of variables and methods within a program.

What is access modifier in Java?
Access Modifiers in Java. As the name suggests access modifiers in Java helps to restrict the scope of a class, constructor, variable, method, or data member.
What is public access modifier?
public: The public access modifier is specified using the keyword public . The public access modifier has the widest scope among all other access modifiers. Classes, methods, or data members that are declared as public are accessible from everywhere in the program. There is no restriction on the scope of public data members.
What does private class mean in Java?
Any other class of the same package will not be able to access these members. private means “only visible within the enclosing class”. Hence these modifiers in terms of application to classes, apply only to nested classes and not on top-level classes.
What to do if other programmers use your class?
If other programmers use your class, try to use the most restrictive access level that makes sense for a particular member. Use private unless you have a good reason not to.
Is class A public in Java?
