title: How do I keep my random match generator from repeating?
body: <p>I've made a random wrestling match generator that I've adapted from a random phrase generator from a textbook. I'd like to know how to make it so the same name isn't done twice on the same run. Can't have The Crusher vs. The Crusher, right?</p>
  
  <pre><code>public class matchOMatic {
      public static void main (String [] args) {
  
      String [] wordListOne = {"The Crusher", "The Main Man", "The Macho-man, Randy Savage", "The Nature Boy, Rick Flare", "Batista", "Hollywood Hulk Hogan", "Vader", "The Undertaker", "Stone Cold Steve Austin" };
      String [] wordListThree = {"The Crusher", "The Main Man", "The Macho-man, Randy Savage", "The Nature Boy, Rick Flare", "Batista", "Hollywood Hulk Hogan", "Vader", "The Undertaker", "Stone Cold Steve Austin"};
  
      int oneLength = wordListOne.length;
      int threeLength = wordListThree.length;
  
      int rand1 = (int) (Math.random() * oneLength);
      int rand3 = (int) (Math.random() * threeLength);
  
      String phrase = wordListOne[rand1] + " and in the opposite corner is his opponent, " + wordListThree[rand3];
  
      System.out.print("In this corner we have " + phrase);
      System.out.println("!");
      }
  }
