Hi,
This question is from jqplus.It goes like this:
Consider:
public class Outer
{
int i = 10;
class Inner
{
public void methodA()
{
//line 1.
}
}
}
Which of the following statements are valid at line 1 (Select the best answer).
1. System.out.println(this.i);
2. System.out.println(i);
3. System.out.println(Outer.this.i);
4. i cannot be accessed inside the inner class method.
Answer given is 3.
Isn't 2. also correct?How does one decide?
Thanks,
Rashmi.

Both 2 and 3 options are correct.
In real Exam, Questions (with choose the best answer) will not be asked.The Questions in real JCP are in very clear language and there is no ambiguity.

Though both 2 and 3 are valid and produces results, the best answer will be 3..
Its is becoz, if we have say i=100; in the Inner class, then the Outer classe's 'i' is shadowed. So to properly access wheather 'i' is shadowed or not, Outer.this.i would be the best practice
Its my humble opinion

I searched for this question ( QID : 970934532250 ) and found that the explanation of this question clearly explains the answer and also notes that this is an ambigous question.
According to our database, a very similar question was asked in the exam.
This is what the explanation says:
-------------------------------
Actually option 2 is also correct but you are asked to select one option so you should select the best answer which is 3.
This sure is an ambigous question but we think that you should select option 3.

Whether this question is an ambiguous one or not will depend on the kind of choice we are required to make. Remember, in the original exam we'll be told "select the one correct answer" and in that case, a radio button (not a check box) will be provided.
If so, then option 3 is correct.
In short, if you see a radio button, hit 3 ... if you see checkboxes, check 2 and 3
But of course, here...we see a "select the best choice" in the brackets...so 3 is correct.
Cheers
Shyam
