请教socket编程的问题
我是菜鸟,刚学socket编程,写了以下代码,想把客户机的asdf asd字符传给服务端,不知道怎么不能实现.所以请教一下.
服务器
import java.io.*;
import java.net.*;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class Server1 {
public static void main(String[] args) throws IOException{
ServerSocket server=new ServerSocket(5678);

Socket client=server.accept();
ObjectInputStream in=new ObjectInputStream(client.getInputStream());
ObjectOutputStream out=new ObjectOutputStream(client.getOutputStream());

try
{
String a=(String)in.readObject();
System.out.println(a);}
catch(ClassNotFoundException cnf)
{cnf.printStackTrace();}
}
}

客户机
import java.net.*;
import java.io.*;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class Client1
{

public static void main(String[] args)throws Exception
{Socket server;
server=new Socket( "127.0.0.1 ",5678);
ObjectInputStream in = new ObjectInputStream(server.getInputStream());
ObjectOutputStream out = new ObjectOutputStream(server.getOutputStream());
out.writeObject( "asdf asd ");
out.flush();

}
}


[解决办法]

客户

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
public class Other extends Frame{
Socket s1=null;
DataOutputStream dos= null;
TextField tfTxt = new TextField();

public static void main(String[] args) {

new Other().lanuchFrame();

}
public void lanuchFrame(){
setLocation(300,400);
this.setSize(300,300);
add(tfTxt,BorderLayout.SOUTH);
add(taConnect,BorderLayout.NORTH);
pack();

this.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e ){
disConnect();
System.exit(0);
}
});
tfTxt.addActionListener(new TFListener());
setVisible(true);
connect();

}
public void disConnect(){
try {
dos.close();
s1.close();
} catch (IOException e) {

e.printStackTrace();
}

}
public void connect()

dos= new DataOutputStream(s1.getOutputStream());
System.out.println( "connect! ");
} catch (UnknownHostException e) {

} catch (IOException e) {

e.printStackTrace();
}
}
private class TFListener implements ActionListener{

String str= tfTxt.getText().trim();

try {
dos.writeUTF(str);
dos.flush();
//dos.close();

} catch (IOException e1) {

e1.printStackTrace();
}
}
}
}

服务

import java.net.*;
import java.io.*;
public class OtherServer {


public static void main(String[] args) {
boolean started=false;
try {
ServerSocket s= new ServerSocket(8888);
started=true;

System.out.println( "a client connected ");
DataInputStream dis = new DataInputStream(ss.getInputStream());
while(connected){

String sr=dis.readUTF();
System.out.println(sr);
}

dis.close();
}


} catch (IOException e) {

e.printStackTrace();
}

}
