I think the wording of the commentary for this question is inaccurate.

class Outsider{
	public class Insider{ }
}
public class TestClass{
	public static void main(String[] args){
		Outsider os = new Outsider();
		// 1 insert line here
	}
}

The commentary for the 4th option

Code: Select all

Insider in = Outsider.new Insider();

says

Outsider.new Insider() is wrong as well because Insider is not static;

but that's not the reason this option is wrong. If Insider were static, the syntax would be

Code: Select all

Outsider.Insider in = new Outsider.Insider();

Actually, it is in connection with option 3, which is, "Outsider.Insider in = os.new Insider();" and the comment for this option "Since Insider is not a static class, it must have an associated outer class instance."

Option 4 replaces the variable os with class name Outsider, so the comment is talking about why replacing os with Outsider will not help.

No big deal, but to me, the flow of that particular explanation seems hard to follow. Cheers.
