title: Create instance of class from other package?
body: <p>I have 2 packages, <code>airline</code> and <code>userInterface</code></p>
  
  <p>In the <code>AirportMain</code> I am trying to create an instance of class <code>AirlineReservation</code> but it is from package <code>userInterface</code>, unlike my <code>AirportMain</code>.</p>
  
  <p>I'm using:</p>
  
  <pre><code>AirlineReservation airlineReservation = new AirlineReservation();
  </code></pre>
  
  <p>but getting an error that it is not public in <code>AirlineReservation</code> so it cannot be accessed outside the package, but I do have:</p>
  
  <pre><code>public class AirlineReservation {
  </code></pre>
  
  <p>in class <code>AirlineReservation</code>. </p>
  
  <p>What am I doing wrong here?</p>
