I think we should talk data structures here, and I think 'heap' would be the best way. Everytime a higher bid is placed, it can take the top position. And if a bid gets cancelled, the heap will re-adjust to bring the highest available bid on top.

how about use priority queue? PriorityQueue<people, price> price is the priority. the higher of the price, the more change to get the product. If a person provide a higher price, change his/her priority

@zhaosonglin. Max - heap based priority queue sounds reasonable. We should have 3 classes: item, user, bid. And basic rules of OO design will follow using inheritance, dynamic binding, observer pattern for notification etc.
