title: Can't call getRandom in main driver Java
body: <p>I have a getRandom method that gets a random integer from an array and return it, but somehow when I try calling the method in my driver, there is an error</p>
  
  <p>"The method getRandom(int[]) in the type europeanroulette is not applicable for the arguments ()"</p>
  
  <p>How would I make this work? I'm just trying to display the int generated by the getRandom method.</p>
  
  <pre><code> public final int[] europeanroulette = {0,32,15,19,4,21,2,25,17,34,6,27,13,36,11,30,8,23,10,5,24,16,33,1,20,14,31,9,22,18,29,7,28,12,35,3,26};
  
  // random number generated from the roulette
       public int getRandom(int[] europeanroulette){
           int winningnumber = new Random().nextInt(europeanroulette.length);
           return winningnumber;
       }
  </code></pre>
  
  <p>And this is from my driver:</p>
  
  <pre><code>int winningnumber = europeanroulette.getRandom();
          System.out.println("The winning number is" + winningnumber );
  </code></pre>
