java – 通过套接字编程报警

当客户端发送与系统服务器相同的时间匹配时间并播放警报时.但是当客户端发送的时间超过1分钟或2分钟时,服务器与系统时间不匹配,不播放警报.

我的代码

服务器端：

public class GraphicsServer extends JFrame implements Runnable
{

    String wr;
    String text;
    JTextField f1;
    JTextField f2;
    JScrollPane js;
    JTextArea jt;
    JPanel p;
    Color color;
    Calendar cal;
    String time;
    String time1;
    int hrs;
    int min;
    int sec;

    public GraphicsServer()
    {
        super("Server Tik Tik Tok");
        setSize(400,400);
        p = new JPanel();
        f1 = new JTextField(10);
        f2 = new JTextField(10);
        p.add(f1);
        p.add(f2);
        add(p);
        Thread thread = new Thread(new Runnable()
        {

            public void run()
            {
                while(true)
                {
                    Calendar now = Calendar.getInstance();
                    int hrs = now.get(Calendar.HOUR_OF_DAY);
                    int min = now.get(Calendar.MINUTE);
                    int sec = now.get(Calendar.SECOND);
                    String time = hrs + ":" + min + ":" + sec;
                    f2.setText(time);
                    time1 = hrs + ":" + min;
                    // System.out.println(time1);
                    // System.out.println(time);
                    try
                    {
                        Thread.sleep(1000);
                    }
                    catch(Exception ee)
                    {
                        System.out.println(ee.getMessage());
                    }
                }
            }
        });
        thread.start();
    }

    public void run()
    {
        try
        {
            ServerSocket server = new ServerSocket(1111);
            while(true)
            {
                Socket ss = server.accept();
                BufferedReader br = new BufferedReader(new InputStreamReader(ss.getInputStream()));
                text = br.readLine();
                f1.setText(text);
                wr = time1;
                if(text.endsWith(wr))
                {
                    color = JColorChooser.showDialog(GraphicsServer.this,"Choose a color",color);
                    p.setBackground(color);
                }
            }
        }
        catch(Exception e)
        {
            System.out.println(e.getMessage());
        }
    }

    public static void main(String[] args)
    {
        GraphicsServer gs = new GraphicsServer();
        gs.setVisible(true);
        Thread th = new Thread(gs);
        th.start();
    }
}

客户端：

public class GrapClient extends JFrame
{

    JButton b1;
    JTextField f1;
    Socket client;

    public GrapClient()
    {
        super("Client Tik Tik Tok");
        setSize(400,400);
        JPanel p = new JPanel();
        b1 = new JButton("Enter Alarm Time");
        f1 = new JTextField(10);
        p.add(b1);
        p.add(f1);
        add(p);
        ActionListener newListener = new ActionListener()
        {

            public void actionPerformed(ActionEvent event)
            {
                try
                {
                    Socket client = new Socket("localhost",1111);
                    PrintStream ps = new PrintStream(client.getOutputStream());
                    String g = f1.getText();
                    ps.println(g);
                    f1.setText("");
                }
                catch(Exception e)
                {
                    System.out.println(e.getMessage());
                }
            }
        };
        b1.addActionListener(newListener);
    }

    public static void main(String[] args)
    {
        GrapClient GC = new GrapClient();
        GC.setVisible(true);
        GC.setResizable(false);
    }
}

我想制作闹钟.在服务器中我将数字时钟嵌入到文本字段中.当客户端向服务器发送闹钟时间时,服务器会将客户端闹钟时间与数字时钟时间进行比较.
如果服务器端的时间是23:10并且客户端同时向服务器发送23:10,则服务器将显示jfile chosser.
如果服务器有时间23:10并且客户端发送报警时间23：11.当服务器时间等于1分钟后客户端报警时间后,服务器将打开jfilechoser.
