title: java force an extending class
body: <p>In Java, can I somehow force a class that extends an abstract class to implement its constructor with a Object as a parameter?</p>
  
  <p>Something like</p>
  
  <pre><code>public abstract class Points {
  
      //add some abstract method to force constructor to have object.
  }
  
  public class ExtendPoints extends Points {
  
      /**
       * I want the abstract class to force this implementation to have
       *  a constructor with an object in it?
       * @param o
       */
      public ExtendPoints(Object o){
  
      }
  }
  </code></pre>
