sweephand.java

一个applet的时钟程序,有删改,基本实现从本地读取时间并用小程序运行.

package clock;

import java.awt.Color;
import java.awt.Graphics;

//秒针使用的类
class SweepHand extends ClockHand 
{
    public SweepHand(int originX,int originY, int length, int points)
    {
        super(originX,originY,length,0,points);
 }

    protected void initiallizePoints(int originX,int originY, int length, int unused) //初始化点
    {
        baseX[0]=originX; baseY[0]=originY;
        baseX[1]=originX; baseY[1]=originY-length/5;
        baseX[2]=originX; baseY[2]=originY+length;
    }

    public void draw(Color color, double angle, Graphics g) //绘制秒针，为线段
    {
        transform(angle);
        g.setColor(color);
        g.drawLine(transX[1],transY[1],transX[2],transY[2]);
    }
}
