title: Suppress any warnings about "unused" variables in Java
body: <p>For some places in my code, I want to have variables that are not sensitive to <em>unused warnings</em> (compiling warn in Eclipse).</p>
  
  <p>So I add annotation <em>@SuppressWarnings("unused")</em>. But after I decided to use that variable and I get a warn <em>Unnecessary @SuppressWarnings("unused")</em>. 
  And I can't disable this warnings in the whole project because I need them in other parts.</p>
  
  <p>How can I make one variable with no warnings in <em>unused</em> or <em>used</em> cases?</p>
