Java Java Basics Perfecting the Prototype Conditional ints

Integer numberOfPeople = 3;

is it wrong?

Integer numberOfPeople = 3;

4 Answers

I'm assuming this is creating a new integer variable, which is something like:

int numberOfPeople = 3;

I'll have a look at the challenge associated with the question.


Yes, that code passes the first part of the challenge.

Small 'i', I think - integer isn't capitalised.

Primitive int is not capitalized but the object one is.

Though you probably have to use a constructor to initialized it.

Integer numberOfPeople = new Integer(3); <-though this depend on the version of java, the later versions probably allow what you are trying to do.

Though it is fine to use the class Integer versus the primitive int in your own code, the challenge checker is probably looking specifically for an int.
