下列Applet程序中，指定s为字符串类型，将s绘制在屏幕上，请将程序补充完整。import java．applet．Applet；import java．awt．Craphics；public class testl8_1 extends Applet {______String s；public void init (){s=new String("Hello World")；}public Void______(Graphics g) {g.______(s，10，25)；}}
A Windows Communication Foundation (WCF) solution uses the following contracts. (Line numbers are included for reference only.)01 [ServiceContract(CallbackContract=typeof(INameService))]02 public interface IGreetingService03 {04 [OperationContract]05 string GetMessage();06 }07 [ServiceContract]08 public interface INameService09 {10 [OperationContract]11 string GetName();12 }The code that implements the IGreetingService interface is as follows:20 public class GreetingService : IGreetingService21{22 public string GetMessage()23 {24 INameService clientChannel = OperationContext.Current.GetCallbackChannel();25 string clientName = clientChannel.GetName();26 return String.Format(Hello {0}, clientName);27 }28 }The service is self-hosted. The hosting code is as follows:30 ServiceHost host = new ServiceHost(typeof(GreetingService));31 NetTcpBinding binding = new NetTcpBinding(SecurityMode.None);32 host.AddServiceEndpoint(MyApplication.IGreetingService, binding, net.tcp//localhost:12345);33 host.Open();The code that implements the lNameService interface is as follows:40 class NameService : INameService41 {42 string name;43 public NameService(string name)44 {45 this.name = name;46 }47 public string GetName()48 {49 return name;50 }51 }Currently, this code fails at runtime, and an InvalidOperationException is thrown at line 25. You need to correct the code so that the call from the service back to the client completes successfully. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)（）
