javaqq聊天界面

㈠ 在java中qq界面中怎麼按enter鍵發送消息

方法一：
importjava.awt.*;
importjavax.swing.*;
importjava.awt.event.*;

{
privateJButtonb1=newJButton("Click");

publicButtonTest(){
this.getContentPane().add(b1);
b1.addKeyListener(this);
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.pack();
}

publicvoidkeyReleased(KeyEventke){
}

publicvoidkeyPressed(KeyEventke){
if(ke.getKeyChar()==ke.VK_ENTER){
System.out.println("ok................");
}
}

publicvoidkeyTyped(KeyEventke){
}

publicstaticvoidmain(String[]args){
newButtonTest().show();
}
}

方法二：
importjava.awt.*;
importjavax.swing.*;
importjava.awt.event.*;

{
privateJButtonb1=newJButton("Click");

publicButtonTest(){
this.getContentPane().add(b1);
b1.addKeyListener(newKeyAdapter(){
publicvoidkeyPressed(KeyEventke){
if(ke.getKeyChar()==ke.VK_ENTER){
System.out.println("ok..............");
}
}
}
);
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.pack();
}

publicstaticvoidmain(String[]args){
newButtonTest().show();
}
}

㈡ 急求JAVA 編輯類似QQ樣子的聊天窗口代碼!!

/**
*網路聊天工具
*左下角輸入框輸入對方的ip地址
*右下角輸入框輸入要發送的消息
*埠號：3000
*接收的消息在上方對話框中顯示，新消息在上面
*/

import java.awt.*;
import java.awt.event.*;
import java.net.*;

class Chat extends Frame
{
List lst = new List(8); //最多顯示六條
TextField tfIP = new TextField(13); //IP地址輸入文本框
TextField tfData = new TextField(50); //定義輸入消息文本框
DatagramSocket ds = null;

public Chat() {
try
{
ds = new DatagramSocket(3000);
}
catch (Exception e)
{
e.printStackTrace();
}
this.add(lst,"Center"); //增加列表框
Panel p = new Panel();
this.add(p,"South");

p.setLayout(new BorderLayout());
p.add(tfIP,"West"); //IP輸入
p.add(tfData,"East"); //消息輸入

new Thread(new Runnable()
{
public void run()
{
byte buf [] =new byte[1024];
DatagramPacket dp = new DatagramPacket(buf,1024);
//顯示消息
while(true)
{
try
{
ds.receive(dp);
lst.add(new String(buf,0,dp.getLength())+
" -->IP："+dp.getAddress().getHostAddress()+" Port:"+dp.getPort(),0);
//新消息指定顯示在第一行
//顯示格式：消息from ip地址：埠號
}
catch (Exception e)
{
if(!ds.isClosed())
{
e.printStackTrace();
}
}
}
}
}).start();

tfData.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
//取出消息及ip文本框中的內容
byte [] buf;
buf =tfData.getText().getBytes();
try
{
DatagramPacket dp = new DatagramPacket(buf,buf.length,
InetAddress.getByName(tfIP.getText()),3000);
ds.send(dp);
}
catch (Exception ex)
{
ex.printStackTrace();
}
//清空
tfData.setText("");
}
});
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
ds.close();
dispose();
System.exit(0);
}
});
}

public static void main(String args[])
{
System.out.println("Starting Chat……");
Chat mainFrame = new Chat();
mainFrame.setSize(500,500);
mainFrame.setTitle("迷你聊天工具");
mainFrame.setVisible(true);
mainFrame.setResizable(false);
}
}
