title: Boolean equals method
body: <p>Writing an abstract class project. Abstract class is the parent class and include a the equals method. Part of my project is to create a Boolean equals method that compares the client IDs (long) of 3 subclasses to make sure that their are not any duplicates IDs. Having an issue implementing the code. Below is what I have so far</p>
  
  <pre><code>public static boolean equals(Object A, Object B, Object C) { 
      if(A.equals(B) || A.equals(C) || B.equals(C)) 
          return true; 
      else 
          return false;
  }
  </code></pre>
  
  <p>Need help dropping the 3 class values for client ID into the code and then incorporating the code into a toString() method.</p>
