title: java how to use classes in other package?
body: <p>can I import,use class from other package?
  In Eclipse I made 2 packages
  one is main other is second</p>
  
  <pre>
  main
   -main (class)
  second
   -second (class)
  </pre>
  
  <p>and I wanted the main function of main class to call the function x in second class.
  how can I do it? I tried:</p>
  
  <pre><code>import second; 
  second.x(); (if both classes are in the same package then it works)
  second.second.x();
  </code></pre>
  
  <p>but none of them worked.
  I'm out of idea now.</p>
