Java BidRequest类使用实例

以下是一个使用Java BidRequest类的示例：

public class BidRequest { private String id; private String placementId; private String publisherId; private double bidAmount; public BidRequest(String id, String placementId, String publisherId, double bidAmount) { this.id = id; this.placementId = placementId; this.publisherId = publisherId; this.bidAmount = bidAmount; } public String getId() { return id; } public String getPlacementId() { return placementId; } public String getPublisherId() { return publisherId; } public double getBidAmount() { return bidAmount; } public void setId(String id) { this.id = id; } public void setPlacementId(String placementId) { this.placementId = placementId; } public void setPublisherId(String publisherId) { this.publisherId = publisherId; } public void setBidAmount(double bidAmount) { this.bidAmount = bidAmount; } public static void main(String[] args) { BidRequest bidRequest = new BidRequest("123456", "placement123", "publisher789", 10.00); System.out.println("Bid Request ID: " + bidRequest.getId()); System.out.println("Placement ID: " + bidRequest.getPlacementId()); System.out.println("Publisher ID: " + bidRequest.getPublisherId()); System.out.println("Bid Amount: $" + bidRequest.getBidAmount()); bidRequest.setBidAmount(15.00); System.out.println("Updated Bid Amount: $" + bidRequest.getBidAmount()); } } 

这个例子中，我们创建了一个BidRequest类，它有四个属性：id、placementId、publisherId和bidAmount。构造函数用于初始化这些属性。然后我们定义了getter和setter方法来访问和修改这些属性。在main方法中，我们创建了一个BidRequest对象，并打印出其属性值。然后，我们修改了bidAmount属性的值，并再次打印出来。
