Question
Which of the following statements regarding constructors are true? You can select more than one statement.Group of answer choicesConstructors can be overloaded.A class can have one and only one constructor.A class can have more than one constructor.Has the same name as the class.You must define at least one constructor for every class you create.
Solution
-
Constructors can be overloaded: True. In many programming languages like Java, C++, etc., constructors can be overloaded. This means you can have multiple constructors in a class, each with a different parameter list.
-
A class can have one and only one constructor: False. A class can have more than one constructor. This is known as constructor overloading.
-
A class can have more than one constructor: True. As mentioned above, a class can have multiple constructors with different parameters. This is known as constructor overloading.
-
Has the same name as the class: True. By definition, a constructor must have the same name as the class. This is how the compiler differentiates a constructor from a regular method.
-
You must define at least one constructor for every class you create: False. If you do not define a constructor for a class, most programming languages will automatically provide a default constructor. However, if you define a constructor yourself, the default constructor will not be provided.
