java闹钟代码

寻找java编程高手写一个闹钟的程序

自己之前做过的一个：

import java.awt.*;

import java.awt.event.*;

import java.util.*;

import javax.swing.*;

import javax.swing.Timer;

public class Clock extends JFrame implements ActionListener {

int x, y, old_X, old_Y, r, x0, y0, w, h, ang;

int sdo, mdo, hdo, old_M, old_H, hh, mm, ss;

int delay = 1000;

Calendar now;

JButton jb;

JMenuBar jmb;

Timer timer;

TimeZone tz = TimeZone.getTimeZone("JST");

Toolkit toolkit=Toolkit.getDefaultToolkit();;

/**

* br

* 方法说明：实现ActionListener类必须过载的方法

*/

public static void main(String[] args) {

Clock cp = new Clock();

cp.setVisible(true);

}

Clock() {

super("Java闹钟！");

setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

setVisible(true);

Container contentPane = getContentPane();

jmb = new JMenuBar();

jm1 = new JMenu("背景颜色设置 ", true);

jmi1 = new JMenuItem("外圈颜色");

jmi1.addActionListener(this);

jmi1.setActionCommand("color1");

jm1.add(jmi1);

jmb.add(jm1);

jmi10=new JMenuItem("使用说明");

jmi10.addActionListener(this);

jmi10.setActionCommand("help");

jl1 = new JLabel("闹铃时间");

alarm = time.getText();

jb = new JButton("修改闹铃时间");

jb.addActionListener(this);

jb.setActionCommand("CC");

ClockPanel clock = new ClockPanel();

contentPane.add(clock, BorderLayout.CENTER);

// 窗体添加事件监听,监听秒表的触发

ActionListener taskPerformer = new ActionListener() {

public void actionPerformed(ActionEvent evt) {

repaint();

};

new Timer(delay, taskPerformer).start();

* 方法说明：绘制图形

Color C1 = Color.lightGray;// 外圈颜色

public class ClockPanel extends JPanel {

public void paint(Graphics g) {

// 绘制圆形

g.setColor(C1);

x = (int) ((r - 10) * Math.cos(RAD * ang) + x0);

y = (int) ((r - 10) * Math.sin(RAD * ang) + y0);

g.drawString("" + i, x, h - y);

// 获取时间

now = Calendar.getInstance();

hh = now.get(Calendar.HOUR_OF_DAY);// 小时

mm = now.get(Calendar.MINUTE);// 分钟

ss = now.get(Calendar.SECOND);// 秒

if (hh 10)

st = "0" + hh;

else

st = "" + hh;

if (mm 10)

st = st + ":0" + mm;

st = st + ":" + mm;

if(alarm.equals(st))

{

if(toolkit!=null)

toolkit.beep();

else {}

if (ss 10)

st = st + ":0" + ss;

st = st + ":" + ss;

// 计算时间和图形的关系

// 擦除秒针

if (old_X 0) {

} else {

old_M = mdo;

old_H = hdo;

// 绘制秒针

g.drawLine(x0, y0, x, (h - y));

old_X = x;

old_Y = y;

// 擦除分针和时针

if (mdo != old_M) {

if (hdo != old_H) {

// 绘制分针

// 绘制时针

} // end paint

// 闹铃时间的判断及实现

// 闹铃声音的实现

public void actionPerformed(ActionEvent e) {

// JMenuItem m = (JMenuItem) e.getSource();

if (e.getActionCommand() == "CC") {

int newHou, newMin;

char c;

String getTime = JOptionPane.showInputDialog(this, "请输入闹铃时间格式如：", "00:00");

//如果撤消设置时间,就什么打印null

if(getTime==null)

System.out.println(getTime);

// dispose();

judge: if (getTime != null) {

//打印输入的设置的时间

JOptionPane.ERROR_MESSAGE);

break judge;

// 判断输入的是不是数字

for (int i = 0; i (getTime.length()); i++) {

c = getTime.charAt(i);

continue;

// 判断当前字符,如果不是数字则跳出该事件

"Error",JOptionPane.ERROR_MESSAGE);

char[] hour = { getTime.charAt(0), getTime.charAt(1) };

newHou = Integer.parseInt(String.valueOf(hour));

newMin = Integer.parseInt(String.valueOf(minute));

"Error", JOptionPane.ERROR_MESSAGE);

new SetTime(newHou, newMin);

if (e.getActionCommand() == "ring1") {

toolkit=Toolkit.getDefaultToolkit();

System.out.println("静音");

toolkit=null;

if (e.getActionCommand() == "color1") {

String color;

Color c;

System.out.println("color1");

if (color == null) {

if (Integer.parseInt(color) 0

else {

c = new Color(Integer.parseInt(color));

C1 = c;

if(color==null){}

if(e.getActionCommand() == "help"){

String help;

help = JOptionPane.showInputDialog(this, "输入quit退出该闹钟的使用", "这是运行在Java中的指针式时钟");

if(help.equals("quit"))

dispose();

else {}

// timer.restart();

class SetTime {

String Hour;

String Minute;

public SetTime() { }

public SetTime(int hour, int minute) {

// 当时间参数小于10的时候在前面添加字符0

if (hour 10) {

Hour = "0" + String.valueOf(hour);

Hour = "" + String.valueOf(hour);

if (minute 10) {

Minute = "0" + String.valueOf(minute);

Minute = "" + String.valueOf(minute);

alarm = Hour + ":" + Minute;

time.setText(alarm);

用JAVA编一个小闹钟

java闹钟程序代码

搞不懂为什么要匿名提问,真的那么怕笑话,不至于吧！

import java.util.Timer;

import java.util.Date;

import java.text.SimpleDateFormat;

public class Alarm

public static void main(String[] args)

Timer timer = new Timer();

try{

timer.schedule(new task(),1000,1000);

catch(IllegalStateException e)

System.out.println("时间到");

static class task extends java.util.TimerTask

public void run()

Date now = new Date();

SimpleDateFormat time = new SimpleDateFormat("HH:mm:ss");

this.cancel();

System.out.println(time.format(now));
