title: What is meant by "implement a wrapper method"?
body: <p>I have been given a programming assignment and one of the things I have to do is implement method which a wrapper method which relies on another method to sort the coordinates from lowest to highest. I am unsure on what exactly is meant by implementing a wrapper method.</p>
  
  <pre><code>static void sortCoordsByZ(double[][] coords) {
      //implement the wrapper method for the recursive sort method. all work is done the recursive sort method
  }
  
  static void recursiveSort(double[][] coords, int lo, int hi) {
      //recursive sort method
  }
  </code></pre>
