title: Implementing a Linked List (java)
body: <p>hello im trying to implement a Linked list in java. 
  As this is a homework assignment I am not allowed to use the built in LinkedList from java.</p>
  
  <p>Currently I have implemented my Node class</p>
  
  <pre><code>public class WordNode
  {
      private String word;
      private int freq;
      private WordNode next;
  
  /**
   * Constructor for objects of class WordNode
   */
  public WordNode(String word, WordNode next )
  {
      this.word = word;
      this.next = next;
      freq = 1;
  
  }
  /**
   * Constructor for objects of class WordNode
   */
  public WordNode(String word)
  {
      this(word, null);
  }
  /**
   * 
   */
  public String getWord()
  {
      return word;
  }
  /**
   * 
   */
  public int getFreq(String word)
  {
      return freq;
  }
  /**
   * 
   */
  public WordNode getNext()
  {
      return next;
  }
   /**
   * 
   */
  public void setNext(WordNode n)
  {
      next = n;
  }
  /**
   * 
   */
  public void increment()
  {
      freq++;
  
  
     }
  }
  </code></pre>
  
  <p>and my "LinkedList"</p>
  
  <pre><code>public class Dictionary
  {
      private WordNode Link;
      private int size;
  
      /**
       * Constructor for objects of class Dictionary
       */
  public Dictionary(String L)
  {
      Link = new WordNode(L);
      size = 1;
  }
  
  /**
   * Return true if the list is empty, otherwise false
   * 
   * 
   * @return 
   */
  public boolean isEmpty()
  {
      return Link == null;
  
  }
  /**
   * Return the length of the list
   * 
   * 
   * @return 
   */
  public int getSize()
  {
      return size;
  }
  /** 
   * Add a word to the list if it isn't already present. Otherwise 
   * increase the frequency of the occurrence of the word. 
   * @param word The word to add to the dictionary. 
   */
  public void add(String word)
  {
  
      Link.setNext(new WordNode(word, Link.getNext()) );
      size++;
  }
  </code></pre>
  
  <p>Im having trouble with implementing my add method correctly, as it has to check the list, for wether the word allready exists and if do not exists, add it to the list and store it alphabetic.
  Ive been working on a while loop, but cant seem to get it to work. </p>
  
  <p>Edit: Ive been trying to print the list but it wont print more than the first added word
  public void print()
  {</p>
  
  <pre><code>    WordNode wn = Link;
      int size = 0;
      while(wn != null &amp;&amp; size &lt;= getSize()){
          System.out.println(wn.getWord()+","+wn.getFreq(wn.getWord()));
          size++;
  
      }  
  } 
  </code></pre>
  
  <p>Any help is appreciated </p>
