The title of your question has nothing to do with your question. — Tobias Otto, Nov 14 '16 at 17:00

When a method is deprecated and used it is not an error, because you can still use it and it should work. A deprecated method means that it is not being supported any more, but you can still use it at your own risk. See this link for more information.

In your case, and to answer your question, Eclipse IS telling you that you are using a deprecated method, by putting a strikethrough line on the method you are using. See the answer in this question to understand why it is not sending the WARNING.

The compiler will send the warning if the deprecated method is in another class. The same thing happens when you compile through cmd.
