title: project hierarchy Idea rather then BlueJ
body: <p>In some Coursera course the expected IDE is BlueJ. Right from the start, I would like to learn how to manage projects with more advanced IDE, like IntelliJ Idea.</p>
  
  <p>The teacher staff provided their framework which they prebuilt in BlueJ.app env. So they don't tell anything about manual import.</p>
  
  <p>I have their framework downloaded in directory <code>edu/duke/bunch-of-java-classes</code> or should I say <code>edu/duke/*.java.</code></p>
  
  <p>On the first line in some class I have <code>import edu.duke.*;</code> aside <code>import java.util.*;</code>, the 2nd one is ok.</p>
  
  <p>How to harness the power <code>edu/duke/*.java.</code>. Where to put it in project hierarchy?</p>
  
  <p>I would like to have them separated. My java classes in, lets say, module1 for week1 and theirs in edu/duke.</p>
