title: Sorting an ArrayList of Person with java collections
body: <p>Below the code I am using works just fine and outputs the names except that the sort method is not working. I expected "Collections.sort(nameFromText);" to sort the ArrayList in alphabetical order by first name.</p>
  
  <p>What am I doing wrong? </p>
  
  <pre><code>public static void main(String[] args) throws IOException {
      // Create and populate text file
      Writer textFile = new FileWriter("names.txt");
      String[] nameArray = new String[] { "Tina Tully\n", "Bill Simpson\n",
              "Dana Smith\n", "Ralph Andrews\n", "Greg Smithers\n",
              "Lisa Krump\n", "Gill Bitters\n", "Barbara West\n",
              "Sandra McDonald\n", "Bart Willis\n", "Bucky Zimmerman\n",
              "Richard Vicks\n", "Velma Tarp\n", "Winslow Tunnell\n",
              "Andrew Letterman\n", "Betty Trump\n", "Waldo Smith\n",
              "Kyle Ronno\n", "Vivian West\n", "Wendy Tunnell\n" };
      generateText(textFile, nameArray);
  
      // Create object of previously created text file
      Scanner pullFile = new Scanner(new File("names.txt"));
  
      // Create 20 Person Objects and add to ArrayList data structure with
      // name variables assigned to values from text file
      ArrayList&lt;Person&gt; nameFromText = new ArrayList&lt;Person&gt;();
      fillArrayList(nameFromText, pullFile);
  
      // Sort ArrayList
      Collections.sort(nameFromText);
  
      // Print ArrayList
      printNamesFromObjects(nameFromText);
  }
  
  private static void printNamesFromObjects(ArrayList&lt;Person&gt; namesFromText) {
      for (int i = 0; i &lt; 20; i++) {
          System.out.println(namesFromText.get(i).name);
      }
  }
  
  private static void fillArrayList(ArrayList&lt;Person&gt; nameFromText,
          Scanner pullFile) {
      while (pullFile.hasNext()) {
          Person obj = new Person(pullFile.nextLine());
          nameFromText.add(obj);
      }
  }
  
  private static void generateText(Writer textFile, String[] nameArray)
          throws IOException {
      for (int i = 0; i &lt; 20; i++) {
          textFile.write(new String(nameArray[i]));
      }
      textFile.close();
  }
