Core Java Programming Course- Access Specifiers in Java

This video tutorial explains the concept of access specifiers in Java, including public, private, and default access levels. It provides examples of how these specifiers affect method visibility within the same class, package, and across different packages. The tutorial also touches on the protected access level, which will be covered in more detail in the context of class inheritance.

Which access specifier allows a method to be accessed from any class in any package?

• Public

• Default

• Protected

• Private

What happens if you replace 'public' with 'private' in a method declaration?

• The method becomes accessible only to subclasses.

• The method becomes accessible within the same package.

• The method becomes accessible only within its own class.

• The method becomes accessible from any package.

Which access level is the most restrictive?

• Public

• Default

• Private

• Protected

What must you do to access a class from a different package?

• Use the 'extends' keyword.

• Declare the class as default.

• Use the 'import' statement.

• Declare the class as private.

Which access specifier allows a method to be accessed within the same package but not outside?

• Protected

• Private

• Default

• Public

What is the default access level if no specifier is mentioned?

• Public

• Private

• Default

• Protected

Which access specifier is similar to default but allows access in subclasses outside the package?

• Protected

• Default

• Private

• Public

What is the access level of a variable declared as 'private'?

• Accessible only within its own class.

• Accessible within the same package.

• Accessible from any package.

• Accessible only to subclasses.

Which access specifier allows a method to be accessed by any class in the same package?

• Default

• Private

• Protected

• Public

What is the significance of the 'protected' access specifier?

• It allows access only within the same class.

• It allows access from any package.

• It allows access within the same package and subclasses outside the package.

• It allows access only to subclasses.
