使用套接字通过TCP从服务器端向客户端发送ArrayList ？

我正在尝试通过TCP将一个对象从服务器端套接字发送到客户端套接字。 我无法找出问题所在。

这是我在客户端遇到的错误：

java.io.EOFException at java.io.ObjectInputStream$PeekInputStream.readFully(ObjectInputStream.java:2280) at java.io.ObjectInputStream$BlockDataInputStream.readShort(ObjectInputStream.java:2749) at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:779) at java.io.ObjectInputStream.(ObjectInputStream.java:279) at ClientSide.main(ClientSide.java:16) 

服务器端代码：

 import java.io.*; import java.net.*; import java.util.ArrayList; public class ServerSide { public static void main(String[] args) { try { ServerSocket myServerSocket = new ServerSocket(9999); Socket skt = myServerSocket.accept(); ArrayList my = new ArrayList(); my.set(0,"Bernard"); my.set(1, "Grey"); try { ObjectOutputStream objectOutput = new ObjectOutputStream(skt.getOutputStream()); objectOutput.writeObject(my); } catch (IOException e) { e.printStackTrace(); } } catch (IOException e) { e.printStackTrace(); } } } 

客户端代码：

 import java.io.*; import java.net.InetAddress; import java.net.Socket; import java.net.UnknownHostException; import java.util.ArrayList; public class ClientSide { public static void main(String[] args) { try { Socket socket = new Socket("10.1.1.2",9999); ArrayList titleList = new ArrayList(); try { ObjectInputStream objectInput = new ObjectInputStream(socket.getInputStream()); //Error Line! try { Object object = objectInput.readObject(); titleList = (ArrayList) object; System.out.println(titleList.get(1)); } catch (ClassNotFoundException e) { System.out.println("The title list has not come from the server"); e.printStackTrace(); } } catch (IOException e) { System.out.println("The socket for reading the object has problem"); e.printStackTrace(); } } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }

从set更改为add可以解决问题

 ArrayList my = new ArrayList(); my.add("Bernard"); my.add("Grey");
