Any class may be inherited by another class in the same package
To answer this question, you need to understand the concept of inheritance in object-oriented programming.
Inheritance is a mechanism in object-oriented programming that allows a class to inherit properties and methods from another class. The class that inherits from another class is called the subclass or derived class, and the class being inherited from is called the superclass or base class.
In Java, when a class is declared with the default access modifier (no access modifier specified), it is only accessible within the same package. This means that only classes in the same package can inherit from it.
So, the statement "Any class may be inherited by another class in the same package" is incorrect. The correct answer is B) False.
Every method of a final class is implicitly final
