title: Java interface with different method parameters
body: <p>I want to have an interface that allows me to use methods with different parameters. Suppose I have an interface:  </p>
  
  <pre><code>public interface Stuff {
      public int Add();
   }
  </code></pre>
  
  <p>And I have two classes A and B who implement the interface.  </p>
  
  <pre><code>public class CLASS A implements Stuff{
      public int Add(int id);
  }  
  
  
  public class CLASS B implements Stuff{
      public int Add(String name);
  }
  </code></pre>
  
  <p>How can I achieve this?</p>
