Quick and Dirty Hackjob demonstrating PriorityQueue's add method add Integers 1-10 on Comparable and then remove them from the head to the end: 
  
  
 import java.util.PriorityQueue; 
  
  
 public class Foo {  
    public static void main ( String args [  ]  )  {  
       PriorityQueue < Integer >  PQ = new PriorityQueue < Integer > ; 
       for ( int i = 0; i  <  10; i++ )  
           PQ.add ( new Integer ( i )  ) ; 
       for ( int i = 0; i  <  10; i++ )  {  
           System.out.println ( "current head is: " + PQ.poll (  )  ) ; 
        }  
     }  
  }
