java的问题，一个简单的聊天程序

lz 你好

具体代码如下:

import javax.swing.*;

public class Chat extends JFrame{

private JLabel enter,start;

private JTextField input;

private JTextArea output;

public Chat() {

super("小程序查看器:Client.class");

enter = new JLabel("html小程序brEnter Text/html");

enter.setFont(new Font("宋体", Font.PLAIN, 12));

start = new JLabel("小程序已启动。");

start.setFont(new Font("宋体", Font.PLAIN, 12));

input = new JTextField(30);

output = new JTextArea(10,35);

output.setEditable(false);

input.addKeyListener(new KeyAdapter(){

public void keyPressed(KeyEvent e){

if(e.getKeyCode() == 10){

output.append(input.getText() + "\n");

}

}

});

setLayout(new FlowLayout(FlowLayout.LEFT,1,1));
