精美时钟（附代码）

java实验一：写一个桌面时钟

java实验⼀：写⼀个桌⾯时钟⼀共有三个类：这个是第⼀个，主函数类：public class Programe extends JFrame {/** 四个部分： 1.画出窗体和⾯板 2.画出指针 3.时间转换的算法 4.让指针动起来*/public static void main(String[] string) {Programe frame = new Programe();// 创建窗体对象frame.setVisible(true);// 设置窗体可见，没有该语句，窗体将不可见，此语句必须有，否则没有界⾯就没有意义}public Programe() {setUndecorated(false);// 打开窗体修饰setAlwaysOnTop(true);// 窗体置顶getContentPane().setLayout(new BorderLayout()); // 在窗体的基础上加⼊⾯板：Panel ⽽后就可以在⾯板上进⾏其他操作 // 指定的组件之间的⽔平间距构造⼀个边界布局setBounds(100, 30, 217, 257);// ⽤于设置窗⼝尺⼨和位置；ClockPaint clockPaint = new ClockPaint();// 创建时钟⾯板getContentPane().add(clockPaint);new Thread() {// 继承Thread类创建线程，更新时钟⾯板界⾯@Overridepublic void run() {// 重写run⽅法try {while (true) {sleep(1000);// 休眠1秒clockPaint.repaint();// 重新绘制时钟⾯板界⾯}} catch (InterruptedException e) {e.printStackTrace();// 在命令⾏打印异常信息在程序中出错的位置及原因。

}}}.start();}}这个是第⼆个，画时钟的类：package clock;import java.awt.BasicStroke;import java.awt.Color;import java.awt.Dimension;import java.awt.Graphics;import java.awt.Graphics2D;import javax.swing.ImageIcon;import javax.swing.JPanel;public class ClockPaint extends JPanel {private static final BasicStroke H = new BasicStroke(4);// 指针粗细private static final BasicStroke M = new BasicStroke(3);private static final BasicStroke S = new BasicStroke(2);private final static int secLen = 60; // 指针长度private final static int minuesLen = 55;private final static int hoursLen = 36;ImageIcon background;// 背景private int X;// 中⼼坐标private int Y;public ClockPaint() {background = new ImageIcon(getClass().getResource("时钟.jpg"));// 加载图⽚int Width = background.getIconWidth();// 获取图⽚宽度X = Width / 2 + 2;// 获取图⽚中间坐标int Height = background.getIconHeight();// 获取图⽚长度Y = Height / 2 - 8;// 获取图⽚中间坐标setPreferredSize(new Dimension(Width, Height));// 设置最好的⼤⼩(固定⽤法)}public void paint(Graphics g) {Graphics2D g2 = (Graphics2D) g;g2.drawImage(background.getImage(), 0, 0, this);ClockData data = new ClockData(secLen, minuesLen, hoursLen);// 绘制时针g2.setStroke(H);// 设置时针的宽度g2.setColor(Color.RED);// 设置时针的颜⾊g2.drawLine(X, Y, X + data.hX, Y - data.hY);// 绘制时针// 绘制分针g2.setStroke(M);// 设置分针的宽度g2.setColor(Color.orange);// 设置时针的颜⾊g2.drawLine(X, Y, X + data.mX, Y - data.mY);// 绘制分针// 绘制秒针g2.setStroke(S);// 设置秒针的宽度g2.setColor(Color.GREEN);// 设置时针的颜⾊g2.drawLine(X, Y, X + data.sX, Y - data.sY);// 绘制秒针// 绘制中⼼圆g2.setColor(Color.BLUE);g2.fillOval(X - 5, Y - 5, 10, 10);}}这个是第三个，获取时钟的数据：package clock;import static java.util.Calendar.HOUR;import static java.util.Calendar.MINUTE;import static java.util.Calendar.SECOND;import java.util.Calendar;public class ClockData {public int sX, sY, mX, mY, hX, hY;public ClockData(int secLen, int minuesLen, int hoursLen) {Calendar calendar = Calendar.getInstance();// 获取⽇历对象int sec = calendar.get(SECOND);// 获取秒值int minutes = calendar.get(MINUTE);// 获取分值int hours = calendar.get(HOUR);// 获取时值// 计算⾓度int hAngle = hours * 360 / 12 + (minutes / 2) ;// 时针⾓度(每分钟时针偏移⾓度）int sAngle = sec * 6; // 秒针⾓度int mAngle = minutes * 6 + (sec / 10);// 分针⾓度// 计算秒针、分针、时针指向的坐标sX = (int) (secLen * Math.sin(Math.toRadians(sAngle)));// 秒针指向点的X坐标(将⾓度转换为弧度) sY = (int) (secLen * Math.cos(Math.toRadians(sAngle))); // 秒针指向点的Y坐标mX = (int) (minuesLen * Math.sin(Math.toRadians(mAngle))); // 分针指向点的X坐标mY = (int) (minuesLen * Math.cos(Math.toRadians(mAngle))); // 分针指向点的Y坐标hX = (int) (hoursLen * Math.sin(Math.toRadians(hAngle))); // 时针指向点的X坐标hY = (int) (hoursLen * Math.cos(Math.toRadians(hAngle))); // 时针指向点的Y坐标}}以上参考了其他⼤佬的代码，等我找到原地址再补上:D做了部分修改，加了部分注释，java⼩⽩还请客官您多多包含呀！。

模拟时钟，把它放在程序中可以给人一种清新的感觉。比起数字时钟来说，有一定的真实感怀旧情结。看到秒针一下一下的转动，时时提醒，时间在不断流逝，要我们珍惜时间。子在川上曰：逝者如斯夫。

JAVA可视化闹钟源码
