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。
