Please Explain

<pre>
public final class Test4 {
class Inner {
void test() {
if (Test4.this.flag); {
sample();
}
}
}
private boolean flag = false;
public void sample() {
System.out.println("Sample");
}
public Test4() {
(new Inner()).test();
}
public static void main(String args []) {
new Test4();
}
}
</pre>
In the above code the answer is printed "Sample" on the standard output. Can anyone please explain why?

More Info on the mentioned Question. It is from John Hunt's Mock Exam, Question 62?

[Darryl Failla]

It's a trick question. Notice the ";" after the "if" statement. In this case, there is no action taken as a result of the "if" determination. The program then will simply go to the next line of code: sample().
While this type of question is fair game in the SCJP exam. I didn't have any of these types of trick questions.

Thanks Darryl
I was confused about 2 things and I noticed the ; after your answer and 1 thing got cleared. The other thing that I was confused about was the use of <OuterClassName>.this.<outerClassMember> but then I read a little bit about it too and cleared that too. Thanks for the timely response and making things clear for me.
