今天模仿着马士兵老师的视频，做了一个即时在线聊天。此时拿出来与大家分享，做的不太好，请大家凑合着看吧
import java.awt.Frame;
public class ChatClient extends Frame {
/**
* @param args
*/
public static void main(String[] args) {
new ChatClient().lanchFrame();
}
public void lanchFrame() {
this.setLocation(400, 400);
this.setSize(300, 300);
setVisible(true);
}
}
效果图
以上只是一个简单的布局，没什么实质性代码。下面给大家讲第二部分
import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.TextArea;
import java.awt.TextField;
public class ChatClient extends Frame {
TextField tftext=new TextField();
TextArea taContent=new TextArea();
public static void main(String[] args) {
new ChatClient().lanchFrame();
}
public void lanchFrame(){
this.setLocation(400, 400);
this.setSize(300, 300);
add(tftext,BorderLayout.SOUTH);
add(taContent,BorderLayout.NORTH);
pack();
setVisible(true);
}
}
第二次比着第一次多了一个输入框。此时只能用右下角的红色按钮关闭。
如图 红色的小正方形
Chat0.3
import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.TextArea;
import java.awt.TextField;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class ChatClient extends Frame {
TextField tftext = new TextField();
TextArea taContent = new TextArea();
public static void main(String[] args) {
new ChatClient().lanchFrame();
}
public void lanchFrame() {
this.setLocation(400, 400);
this.setSize(300, 300);
add(tftext, BorderLayout.SOUTH);
add(taContent, BorderLayout.NORTH);
pack();
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// TODO Auto-generated method stub
System.exit(0);
}
});
setVisible(true);
}
}
Chat0.4
import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.TextArea;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class ChatClient extends Frame {
TextField tftext = new TextField();
TextArea taContent = new TextArea();
public static void main(String[] args) {
new ChatClient().lanchFrame();
}
public void lanchFrame() {
this.setLocation(400, 400);
this.setSize(300, 300);
add(tftext, BorderLayout.SOUTH);
add(taContent, BorderLayout.NORTH);
pack();
this.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// TODO Auto-generated method stub
System.exit(0);
}
});
tftext.addActionListener(new TFListener());
setVisible(true);
}
private class TFListener implements ActionListener{
@Override
public void actionPerformed(ActionEvent e) {
String s=tftext.getText().trim();
taContent.setText(s);
tftext.setText("");
}
}
}
Chat0.4在输入框内输入内容后按回车键可以直接发送。
Chat0.5比0.4多了一个服务端。废话不多说，直接上代码。
import java.io.IOException;
import java.net.ServerSocket;
public class ChatServer {
public static void main(String[] args) {
try {
ServerSocket ss=new ServerSocket(8888);
} catch (IOException e) {
e.printStackTrace();
System.out.println("a client connected");
}
}
