求解决客户端写出的字符串为什么不能在服务器端控制台显示。
代码如下：
客户端：import java.awt.*;
import java.io.*;
import java.net.*;
import java.awt.event.*;

public class ChatClient extends Frame {

Socket s = null;
DataOutputStream dos = null;

TextField tfTxt = new TextField();
TextArea tfContent = new TextArea();

public static void main(String[] args) {
new ChatClient().launchFrame();

}

public void launchFrame() {
setBounds(300, 300, 400, 400);
add(tfTxt, BorderLayout.SOUTH);
add(tfContent, BorderLayout.NORTH);
pack();
this.addWindowListener(new WindowAdapter(){

@Override
public void windowClosing(WindowEvent e) {
disConnect();
System.exit(0);
}

}
);
tfTxt.addActionListener(new TFListener());
setVisible(true);
connect();
}

public void connect() {
try {
s = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(s.getOutputStream());
System.out.println("connected");
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

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

}

private class TFListener implements ActionListener {

@Override
public void actionPerformed(ActionEvent e) {
String str = tfTxt.getText().trim();
tfContent.setText(str);
tfTxt.setText("");
try {
dos.writeUTF(str);
dos.flush();
} catch(IOException ae) {
ae.printStackTrace();
}
}

}
}
服务器端：
import java.io.*;
import java.net.*;

public class ChatServer {
public static void main(String[] args) {
boolean started = false;
try {
ServerSocket ss = new ServerSocket(8888);
started = true;
while(started) {
boolean bconnected = false;
Socket s = ss.accept();
System.out.println("a client content");
bconnected = true;
DataInputStream dis = new DataInputStream(s.getInputStream());
while(bconnected) {
String str = dis.readUTF();
System.out.println(str);
}
dis.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}


------解决方案--------------------
你在客户端是不是没有创建连接调用这个函数哦：
public void connect() 

------解决方案--------------------
你客户端有问题，没有放数据进去，服务器就一直等着
try {
s = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(s.getOutputStream());
System.out.println("connected");} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

改为
try {
s = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(s.getOutputStream());
dos.writeUTF("Hello,kitty!");
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

------解决方案--------------------
没有问题啊，用你的代码测试了一下，服务器是输出了客户端传过去的字符串。建议你检查一下你的socket是否连接正确。这句有输出么？

Java code

System.out.println("connected");
