title: Exception in thread "main" java.lang.Error: Unresolved compilation (PhraseOMatic)
body: <p>I tried to run the code from Head First Java as the following:</p>
  
  <pre><code>public class PhraseOMatic {
     public static void main(String[] args){
  
      String[] wordListOne = {"24/7", "mult-iTier", "30,000 foot", "B-to-B", "win-win", "front-end", "web-based", "pervasive", "smart", "six-sigma", "critical-path", "dynamic"};
  
      String[] wordListTwo = {"empowered", "sticky", "value-added", "oriented", "centric", "distributed", "clustered", "branded", "outside-the-box", "positioned", "networked", "focused", "leveraged", "aligned", "targeted", "shared", "cooperative", "accelerated"};
  
      String[] wordListThree = {"process", "tipping-point", "solution", "architecture", "cor competency", "strategy", "mindshare", "portal", "space", "vision", "paradigm", "mission"};
  
      int oneLength = wordListOne.length;
      int twoLength = wordListTwo.length;
      int threeLength = wordListThree.length;
  
      int rand1 = (int) (Math.random() * oneLength);
      int rand2 = (int) (Math.random() * twoLength);
      int rand3 = (int) (Math.random() * twoLength);
  
      String phrase = wordListOne[rand1] + " " + wordListTwo[rand2] + " " + wordListThree[rand3];
  
      System.out.println("What we need is a " + phrase);
      }
  }
  </code></pre>
  
  <p>and it is here that I receive this error:</p>
  
  <p>Exception in thread "main" java.lang.Error: Unresolved compilation problem: </p>
  
  <pre><code>at PhraseOMatic.main(apples.java:2)
  </code></pre>
  
  <p>I see from the error that the problem is in line 2, but I can identify the error</p>
