java新手..求救!求救!...请各位高手帮帮忙!..
如何将以下小时钟从JFrame变成JPanel类:import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Clock extends JFrame {
public Clock() {
ClockPaint cp = new ClockPaint(20, 20, 70);
this.add(cp);
this.setSize(200, 200);
this.setResizable(false);
this.setLocation(260, 120);
this.setTitle("小时钟");
this.setVisible(true);
}
public static void main(String[] s) {
new Clock();
}
}
class ClockPaint extends JPanel implements Runnable {
int x, y, r;
int h, m, s;//小时，分钟，秒
double rad = Math.PI / 180;
public ClockPaint(int x, int y, int r) {
this.x = x;
this.y = y;
this.r = r;
Calendar now = new GregorianCalendar();
s = now.get(Calendar.SECOND) * 6;//获得秒转换成度数
m = now.get(Calendar.MINUTE) * 6;//获得分钟
h = (now.get(Calendar.HOUR_OF_DAY) - 12) * 30 + now.get(Calendar.MINUTE) / 12 * 6;//获得小时
Thread t = new Thread(this);
t.start();
}
public void paint(Graphics g) {
//清屏
super.paint(g);
g.setColor(Color.BLACK);
g.fillRect(0, 0, r * 3, r * 3);
//画圆
g.setColor(Color.WHITE);
g.drawOval(x, y, r * 2, r * 2);
//秒针
g.setColor(Color.RED);
int x1 = (int)((r - 10) * Math.sin(rad * s));
int y1 = (int)((r - 10) * Math.cos(rad * s));
g.drawLine(x + r, y + r, x + r + x1, y + r - y1);
//分针
g.setColor(Color.BLUE);
x1 = (int)((r - r / 2.5) * Math.sin(rad * m));
y1 = (int)((r - r / 2.5) * Math.cos(rad * m));
g.drawLine(x + r, y + r, x + r + x1, y + r - y1);
//时针
g.setColor(Color.CYAN);
x1 = (int)((r - r / 1.5) * Math.sin(rad * h));
y1 = (int)((r - r / 1.5) * Math.cos(rad * h));
g.drawLine(x + r, y + r, x + r + x1, y + r - y1);
//数字
g.setColor(Color.YELLOW);
int d = 29;
for (int i = 1; i <= 12; i++) {
x1 = (int)((r - 10) * Math.sin(rad * d));
y1 = (int)((r - 10) * Math.cos(rad * d));
g.drawString(i + "", x + r + x1 - 4, x + r - y1 + 5);
d+=30;
}
//小点
d = 0;
for (int i = 0; i < 60; i++) {
x1 = (int)((r - 2) * Math.sin(rad * d));
y1 = (int)((r - 2) * Math.cos(rad * d));
g.drawString(".", x + r + x1 - 1, x + r - y1 + 1);
d+=6;
}
//显示时间
Calendar now1 = new GregorianCalendar();
g.drawString(now1.get(Calendar.HOUR_OF_DAY) + "：" + now1.get(Calendar.MINUTE) + "：" + now1.get(Calendar.SECOND), 0, 10);
}
public void run() {
while (true) {
try {
Thread.sleep(1000);
}
catch (Exception ex) {
}
s+=6;
if (s >= 360) {
s = 0;
m+=6;
if (m == 72 || m == 144 || m == 216 || m == 288) {
h+=6;
}
if (m >= 360) {
m = 0;
h+=6;
}
if (h >=360) {
h = 0;
}
}
this.repaint();
}
}
}
然后插入一个拥有日历,记事本..的窗口里面.
日历记事本主程序如下:

JPanel northPanel,southPanel;
public CalendarPad(int year,int month,int day)
{
northPanel=new JPanel(); //左边日历

northPanel.validate();
