title: Java: Importing resources, the use of "*"?
body: <p>I am currently working on a tutorial that uses the following imports:</p>
  
  <pre><code>//importing Resources
  import java.awt.*;
  import java.awt.event.ItemEvent;
  import java.awt.event.ItemListener;
  import javax.swing.*;
  </code></pre>
  
  <p>My question is: does java.awt.* import everything from awt? And if so why is this necessary?</p>
  
  <pre><code> import java.awt.event.ItemEvent; 
  </code></pre>
