 public static boolean isconsecutive(priorityqueue o){ >           if(o.isempty()){ >               return true; >           } >           while(!(o.isempty())){ >             >               if(o.poll() ==o.peek()){ >                   return true; >               } >           } >           return false;    >       } 

your function should take priorityqueue<integer> object rather plain priorityqueue. o.poll() o.peek() return integers rather plain objects.

once have integers work with, can use regular + operator.
