swing程序设计 1.编写一个程序实现鼠标事件、窗口事件。2.socket编程，要求：创建服务端，往客户端发送信息，创建客户端

好的，我可以回答你的问题。

1. 编写一个程序实现鼠标事件、窗口事件：

以下是一个简单的Swing程序，可以实现鼠标事件和窗口事件。当用户单击窗口时，会弹出一个对话框显示“Hello World!”；当用户单击按钮时，会在控制台输出“Button clicked!”。

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class MyWindow extends JFrame implements MouseListener {
    private JButton button;

    public MyWindow() {
        super("My Window");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // 添加按钮
        button = new JButton("Click me");
        button.addMouseListener(this);
        getContentPane().add(button, BorderLayout.CENTER);

        // 添加窗口事件
        addWindowListener(new WindowAdapter() {
            public void windowActivated(WindowEvent e) {
                System.out.println("Window activated");
            }
            public void windowClosed(WindowEvent e) {
                System.out.println("Window closed");
            }
            public void windowClosing(WindowEvent e) {
                System.out.println("Window closing");
            }
            public void windowDeactivated(WindowEvent e) {
                System.out.println("Window deactivated");
            }
            public void windowDeiconified(WindowEvent e) {
                System.out.println("Window deiconified");
            }
            public void windowIconified(WindowEvent e) {
                System.out.println("Window iconified");
            }
            public void windowOpened(WindowEvent e) {
                System.out.println("Window opened");
            }
        });

        pack();
        setVisible(true);
    }

    public void mouseClicked(MouseEvent e) {
        if (e.getSource() == button) {
            System.out.println("Button clicked!");
        }
    }
    public void mouseEntered(MouseEvent e) {}
    public void mouseExited(MouseEvent e) {}
    public void mousePressed(MouseEvent e) {}
    public void mouseReleased(MouseEvent e) {}

    public static void main(String[] args) {
        new MyWindow();
    }
}

2. Socket编程，要求：创建服务端，往客户端发送信息，创建客户端：

以下是一个简单的Socket编程程序，可以创建服务端和客户端，并实现信息发送和接收。服务端启动后，等待客户端连接；客户端连接后，可以向服务端发送消息，服务端接收到消息后会在控制台输出，并回复客户端“Message received”。

服务端程序：

import java.io.*;
import java.net.*;

public class Server {
    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(1234);
            System.out.println("Server started");

            Socket socket = serverSocket.accept();
            System.out.println("Client connected");

            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);

            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                System.out.println("Received message: " + inputLine);
                out.println("Message received");
            }

            in.close();
            out.close();
            socket.close();
            serverSocket.close();
        } catch (IOException e) {
            System.out.println("Error: " + e.getMessage());
        }
    }
}

客户端程序：

import java.io.*;
import java.net.*;

public class Client {
    public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost", 1234);
            System.out.println("Connected to server");

            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);

            BufferedReader userIn = new BufferedReader(new InputStreamReader(System.in));

            String inputLine;
            while ((inputLine = userIn.readLine()) != null) {
                out.println(inputLine);
                System.out.println(in.readLine());
            }

            in.close();
            out.close();
            socket.close();
        } catch (IOException e) {
            System.out.println("Error: " + e.getMessage());
        }
    }
}
