title: Finding the mode of an array method (java)
body: <p>I have to write methods to find the mean, median, mode, etc given an array of numbers. I've gotten everything else worked out, but mode is giving me a hell of a time and don't know why. </p>
  
  <p>The array is 22, 26, 45, 46, 49, 55, 57, 63, 63, 65, 66, 67, 67, 68, 68, 69, 70, 71, 72, 73, 75, 76, 76, 77, 77, 78, 78, 78, 79, 82, 82, 83, 84, 85, 87, 88, 88, 89, 89, 91, 92, 98, 99</p>
  
  <p>It is returning 22, when the answer should be 78. </p>
  
  <p>Here is my code: </p>
  
  <pre><code>public static int mode(int[] array){
      int[] countArray = new int[101];
  
      //counts each number
      for(int i = 0; i &lt; array.length; i++){
        countArray[array[i]]++;
      }// end for loop
  
      int mode = array[0], modeIndex = 0;
  
      //finds which number occurs the most
      System.out.println(Arrays.toString(countArray));
      for(int i = 1; i &lt; array.length; i++){
        if(countArray[i] &gt; mode){
  
          mode = countArray[i];
          modeIndex = i;
          System.out.println(mode + " " + modeIndex);
        }// end if
      }// end for loop
  
      return modeIndex;
  }// end method mode
  </code></pre>
