title: Create word count of text using hashmap
body: <p>I am trying to create a program as a tutorial for myself for hashmaps. I ask the user into text and try to split it into hashmaps and then increase the count if the word repeats. This is my program:</p>
  
  <pre><code>import java.util.*;
  import java.lang.*;
  import javax.swing.JOptionPane;
  import java.io.*;
  public class TestingTables
  {
     public static void main(String args[])
     {
        {
        String s = JOptionPane.showInputDialog("Enter any text.");
        String[] splitted = s.split(" ");
        HashMap hm = new HashMap();
        int x;
  
        for (int i=0; i&lt;splitted.length ; i++) {
           hm.put(splitted[i], i);
           System.out.println(splitted[i] + " " + i);
           if (hm.containsKey(splitted[i])) {
               x = ((Integer)hm.get(splitted[i])).intValue();
               hm.put(splitted[i], new Integer(x+1)); }
           }
        }
     }
  }
  </code></pre>
  
  <p>When I input "random random random", I get:
      random 0
      random 1
      random 2</p>
  
  <p>What do I need to change so I get:
      random 3
  Also, do I need to use an iterator to print out the hashmap, or is what I used OK?</p>
