16 Which of the following statements are true?

  1. a. All of the variables in an interface are implicitly static

  2. b. All of the variables in an interface are implicitly final

  3. c. All of the methods in an interface are implicitly abstract

  4. d. A method in an interface can access class level variables


Correct Option: A,B,C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) All of the variables in an interface are implicitly static - This option is true. In an interface, all variables are implicitly static, meaning they belong to the interface itself rather than any specific instance.

Option B) All of the variables in an interface are implicitly final - This option is true. In an interface, all variables are implicitly final, meaning their values cannot be changed once they are assigned.

Option C) All of the methods in an interface are implicitly abstract - This option is true. In an interface, all methods are implicitly abstract, meaning they do not have a body and must be implemented by any class that implements the interface.

Option D) A method in an interface can access class-level variables - This option is false. Methods in an interface can only access variables declared within the interface itself. They cannot access variables from implementing classes or any other classes.

The correct answer is A, B, C. These options are correct because variables in an interface are implicitly static and final, and methods in an interface are implicitly abstract.
