I was trying to post a question just now, but I was always told "This post does not meet our quality standards" when I clicked the "Post Your Question" button. Why? The screenshot of my question is here:

Low quality post

This question came from our site for professional and enthusiast programmers.

Your screenshot does not show the title, which is important in the quality filter. What was it? – Joachim Sauer May 15 '13 at 8:52
@JoachimSauer "what is the endianness of int in Java?" – Bart May 15 '13 at 8:54
Yes, but how did u know that? I haven't posted it yet. – user2384994 May 15 '13 at 8:55
See the title bar of the browser !!!! – NINCOMPOOP May 15 '13 at 8:56
:-). So, could you please answer that endianness question first? – user2384994 May 15 '13 at 8:57
Oops, I've missed that ;-) – Joachim Sauer May 15 '13 at 8:57
@user2384994: actually the endianness of variables is not defined in Java, as there is no way you can ever observe it. Only when you convert them into bytes will you be able to see an endianness and then it depends on how the conversion is done. Also, I'm pretty sure that's a duplicate of another question on SO. – Joachim Sauer May 15 '13 at 8:58
I'm not sure what the site rule on the matter is, but I would tend to shorten titles by turning a question into a statement, then have the question as first line of content. E.G. the title might be "Endianness of int in Java". Often I'd remove 'in Java' as well, but here it seems directly relevant to the inquiry. – Andrew Thompson May 15 '13 at 9:02
By "when you convert them into bytes" do you mean "when you convert them into bytecodes"? So, the author made a mistake, right? The excerption of the book is here: – user2384994 May 15 '13 at 9:04
@user2384994: no, i meant "into bytes". "into bytecodes" is not meaningful here. Bytecode is the native binary format in which executable Java code is represented and is not at all relevant to this discussion. (Oh, and yes: I'd say the author is wrong, because endianness of variables in Java is pretty much undefined). – Joachim Sauer May 15 '13 at 9:12
I see. Thank you, Joachim. – user2384994 May 15 '13 at 9:19

This answer here explains it all. Excerpts are :

Make sure your question has

  1. a clear title
  2. a reasonable explanation of what your question is, sharing your research on the matter
  3. correct use of English and actual sentences
  4. proper spelling, grammar, capitalization, and punctuation

If your question is so brief that it could be looked up in a dictionary or reference book/site trivially, it might not be a good fit on our network.

Thank you. So the reason is that my question is so brief? But the error message appears immediately after I clicked the post button, so the briefness of the question should be judged by computer, not by human. So, how long can make the server think my question is not brief? – user2384994 May 15 '13 at 9:14
@user2384994: The computer algorithms are kept secret so that human beings can't come up with posts that are "just under the wire." Basically, you need a decent title and a "reasonable" amount of text to past the filter. – Tom Au May 15 '13 at 13:25
