Question
Select the correct answerWhat is true about constructor?OptionsIt can contain return type It can take any number of parametersIt can have any non access modifiersConstructor cannot throw an exception
Solution
The correct answer is: It can take any number of parameters.
Explanation:
-
A constructor cannot contain a return type. By definition, a constructor in Java doesn't have a return type. Its name is the same as the class name and it is used to initialize the instance variables of a class.
-
A constructor can take any number of parameters. This is true. A constructor can take zero, one, or multiple parameters.
-
A constructor cannot have any non-access modifiers. Constructors can only have access modifiers (public, private, protected).
-
A constructor can throw an exception. This is true. If there is a possibility of an exception being thrown in the constructor's code, it should be handled with a 'throws' keyword.
