怎么用java编写时钟呀？import
java.util.*;
import
java.awt.*;
import
java.applet.*;
//impelements
Runnable
是线程程序的接口
public
class
Clock
extends
Applet
implements
Runnable
{
Thread
timer
=
null;
//
定义线程实体timer
int
xcenter
=
400,
ycenter
=
50;
int
Radius
=
ycenter
-
5;
public
void
init()
{
resize(400,
125);//
设置时钟程序的窗口大小
setBackground(Color.white);//
设置小应用程序的背景色
}
public
void
paint(Graphics
g)
{
int
xh,
yh,
xm,
ym,
xs,
ys,
s,
m,
h;
String
today;
Date
dat
=
new
Date();
//
定义时间类dat
s
=
dat.getSeconds();
//
获得时间秒
m
=
dat.getMinutes();
//
获得时间分
h
=
dat.getHours();
today
=
dat.toLocaleString();
//
获得字符串时间格式
g.clearRect(0,
0,
size().width,
size().height);
//
消除小应用程序
xcenter
=
xcenter
