About Question enthuware.ocpjp.v11.2.3503 :

[mesginaa01]

public class TestOuter { public static class TestInner {
public void sayIt(){ System.out.println("hello"); } }
public static void main(String[] args){
//call here
} }

Why TestInner.sayIt(); cannot be the the second answer?

As the explanation for this options says:

TestInner is static but its method sayIt is not. So, you need to do new TestInner().sayIt(); in main to invoke sayIt.

You can actually try it out.

Hello, question:

new TestOuter.TestInner() -> are we using this call because TestInner is static? Thanks

[admin]

Yes, that is correct. Just like you refer to any other static member of a class.
