Write an Auction system Online Auction Coding Sample Instructions Implement a solution to the following problem using the latest released version of Java. Your project should include unit tests using the open source JUnit framework. The program should be an object-oriented API and should not include a user interface of any kind. There is no need to provide any form of data persistence. We are looking for clean, well-factored, object-oriented code that has accompanying JUnit tests. Here are the requirements: Consider a new and different computerized auction site where a seller can offer an item up for sale and people can bid against each other to buy the item. The company building this site has asked you to come up with the algorithm to automatically determine the winning bid after all bidders have entered their information on the site. Your API will be integrated into the site by other developers working on the project. The site will allow each bidder to enter three parameters: Starting bid - The first and lowest bid the buyer is willing to offer for the item. Max bid - This maximum amount the bidder is willing to pay for the item. Auto-increment amount - A dollar amount that the computer algorithm will add to the bidder's current bid each time the bidder is in a losing position relative to the other bidders. The algorithm should never let the current bid exceed the Max bid. The algorithm should only allow increments of the exact auto-increment amount.
