why was my answer to a question got deleted?

Question

I am curious why my answer was deleted to this question? Looking at the FAQ section, I do not see which one it falls under. I was the first to answer so it can't be that my answer is too similar to others.

If someone could explain the rationale I would really appreciate it!

Here is the content of my answer:-

You definitely can switch on enums. An example posted from the java tutorials.

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY, 
    THURSDAY, FRIDAY, SATURDAY 
 }

public class EnumTest {
    Day day;

public EnumTest(Day day) {
    this.day = day;
}

public void tellItLikeItIs() {
    switch (day) {
        case MONDAY: System.out.println("Mondays are bad.");
                     break;

        case FRIDAY: System.out.println("Fridays are better.");
                     break;

        case SATURDAY:
        case SUNDAY: System.out.println("Weekends are best.");
                     break;

        default:     System.out.println("Midweek days are so-so.");
                     break;
    }
}

Answer 1

I can not tell you why Robert deleted this, I do not know.

But I went ahead and undeleted. Nonetheless, the question itself is a train-wreck it is 2 hours old, with 4 duplicate answers.

I try to avoid adding an answer unless my answer is going to add something materially new to the question, it appears that in this question people are more focused at getting rep, than creating a resource that others can easily consume.

Answer 2

I'll give you another reason why...

Betcha somebody flagged as "not a real answer." A casual glimpse would tend to support this. Your answer is riding the line between what can be considered an answer and what should be just a comment. One mod might let it stand, another might convert it to a comment, and another might delete it. Its not the best situation, but that's what happens in grey areas--we make a call based on our best judgement.

Answers should, hypothetically, stand on their own. A better version of your answer would include more than one line. An example would have been great, rather than just pointing to an example on a different site.
