title: How to allow import to intelliJ - all imports are unused
body: <p>I am newbie in programing. I use IntelliJ IDEA v.14.0.
  I try to learn some Java basics, but when I enter at the beginning of the <code>import java.util.*;</code> it becomes </p>
  
  <blockquote>
    <p>Unused import statement</p>
  </blockquote>
  
  <p>That happens when I add semicolon at the and of the row.
  <a href="http://postimg.org/image/frh7o7dix/" rel="nofollow">Unused import statement</a></p>
  
  <p>Instead of just to import <code>import java.util.*;</code> I have to write in the <a href="http://postimg.org/image/kc1dhvewv/" rel="nofollow">code</a> every time <code>java.util.Arrays.sort(int_array1);</code></p>
  
  <p>I tried many different classes to import, but all they become "Unused import statement"</p>
  
  <p>How can I import classes without this problem?</p>
