    Default Why is system.println printing a reference number

    [I am trying to print the output of lot.getHighestBid, which is just a number but for whatever reason, it prints the reference number @234lln. What is wrong with my code?
     public void close()
            for(Lot lot : lots){
                Bid bid = lot.getHighestBid();
                if(bid != null)
                    System.out.println("Sold to: " + lot.getHighestBid().getBidder().getName() + " for: " + lot.getHighestBid()  );

    --- Update ---

    Never mind. Mods could close this thread or remove it. I just found out after hours of scratching my head that I should use lot.getValue() method.

    For other people looking at this same problem. If this is showing for a class that you built, it may be beneficial to overwrite the toString() method. For instance if you do it the way shown below. Saves headaches and will also help if you are debugging in Eclipse. The variables display with their toString() values.
    public String toString() {
    	return this.getValue();
