Question

Which of the following is false about an empty class you have just coded. Select one:

a. It has a super class
b. It has a toString method
c. It has a constructor
d. A subclass of it could be coded
e. Select this option if you think none of the above are false

Answer 1

Option (e) is the correct answer: 'Select this option if you think none of the above are false,' because all given statements about an empty class are indeed true.

Step-by-step explanation:

The question asks which of the following is false about an empty class you have just coded. Reviewing each statement:

• a. It has a super class - This is true for an empty class in Java, as it implicitly extends from the Object class.
• b. It has a toString method - This is also true. Since every class in Java inherits from the Object class, which provides a default implementation of the toString() method, an empty class also has this method.
• c. It has a constructor - True again; Java provides a default no-argument constructor if no other constructors are explicitly defined.
• d. A subclass of it could be coded - Correct; you can create subclasses of any class that is not declared as final.
• e. Select this option if you think none of the above are false - This is the correct answer as all the previous statements are true.
