Question
Which of the following is true about constructors?
- They cannot be virtual.
- They cannot be private.
- They are automatically called by new operator.
Solution
To answer the question about constructors, let's go through each statement one by one:
-
They cannot be virtual: This statement is true. Constructors cannot be declared as virtual in most programming languages. The purpose of a constructor is to initialize an object when it is created, and making it virtual would not make sense as it is called automatically during object creation.
-
They cannot be private: This statement is false. Constructors can be declared as private in some programming languages. When a constructor is private, it means that it can only be accessed within the class itself. This is often used in scenarios where you want to control the creation of objects and restrict access to the constructor.
-
They are automatically called by the new operator: This statement is true. When you use the new operator to create an object, the constructor of that class is automatically called. The constructor is responsible for initializing the object's state and allocating any necessary resources.
So, to summarize:
- Constructors cannot be virtual.
- Constructors can be private in some programming languages.
- Constructors are automatically called by the new operator.
