What is an example for access specifier?
The public keyword is an access specifier. Access specifiers define how the members (attributes and methods) of a class can be accessed. In the example above, the members are public – which means that they can be accessed and modified from outside the code.
What is private access specifier explain with an example how is it different from public and protected access specifiers?
Private: The access level of a private modifier is only within the class. It cannot be accessed from outside the class. If you do not specify any access level, it will be the default. Protected: The access level of a protected modifier is within the package and outside the package through child class.
What is the need for access modifiers?
Access modifiers are there to set access levels for classes, variables, methods and constructors. This provides an individual with the chance of controlling better the privacy of the application.

What is the significance of using access specifiers mention different access specifiers?
The data members and member functions can be accessed using access specifiers. They define the scope of members. The different access specifiers are private, protected and public.
Is it possible to access data outside a class?
Yes, you can access data members and functions outside of the class by the help of public and protected access specifiers.
What is the difference between private access and package access?
Private members cannot be accessed from non-child classes of the same package. Protected member can be accessed from non-child classes of the same package. Package member can be accessed from non-child class of the same package. Package members cannot be accessed from the child class of outside package.
What are the advantages of access specifiers in Java?
The main advantage of access specifiers is because we can restrict certain variables, methods to certain classes, methods, etc. 1. Public 2. Private 3. Protected 4. Default (no access specifier mentioned) Let us learn about all four specifiers one by one with an example.
What are private and Protected Access specifiers in Java?
Private specifiers are meant to have the lowest level of accessibility among all specifiers. If we declare class, method, fields, variables as private. And these can be accessed only within the class. This specifier is completely opposite to that of a public class. We use protected access specifier to a method or a variable.
What are the different types of access specifiers?
The access specifiers are listed according to their restrictiveness order. 1) private (accessible within the class where defined) 2) default or package private (when no access specifier is specified) 3) protected. 4) public (accessible from any class)
What are the different types of access modifiers in Java?
These access modifiers apply to types only (classes, interfaces, enums and annotations). Member-level access modifiers: public, protected, default and private. These access modifiers apply to fields, constructors and methods. So we can see, there are 4 different access modifiers: public, protected, default and private.
