pls hlep, can't get output
This is program.But problem is that there is no output.I faded to
catch the problem.
import java.awt.*;
import javax.swing.*;
import java.util.Calendar;
class ClockDemo extends Canvas{
int xmou 0; //set the center of circle
int ymou 0; //set the center of circle
double theta=-0.1047; //theta for second's hand
int x=xmou; //x position of Second's hand
int y=ymou; //y position of second's hand
int p,b;
int h;
boolean flag=true;
/*ClockDemo(){
//super();
setSize(500,500);
setBackground(Color.PINK);
setVisible(true);
}*/
public void paint(Graphics g){
DrawLine(g,xmou,ymou,x,y);
}
public void DrawLine(Graphics g,int startX,int startY,int endX,int
endY){
h=80;
System.out.println("h:"+h);
//g.drawLine(200,200,165,248);
while(true){
g.drawLine(startX,startY,endX,endY);
newpoint();
//this.repaint(startX,startY,endX,endY);
try{
Thread.sleep(1000);
}catch(Exception e){}
}
}
public void newpoint(){
Calendar now = Calendar.getInstance(); //creating a Calendar
variable for getting current time
//for second hand
//h=60;
x=xmou;
y=ymou;
theta=-0.1047;
theta=theta*now.get(Calendar.SECOND);
System.out.println("theta:"+theta);
p= (int) (Math.sin(theta) * h);
b= (int) (Math.cos(theta) * h);
System.out.println("p:"+p+" "+"b:"+b);
x=x-p;
y=y-b;
}
For veiwing
import javax.swing.*;
import java.awt.*;
class ClockDemoViewer {
public static void main(String... arg){
ClockDemo comp=new ClockDemo();
JFrame jf=new JFrame("Clock Demo");
jf.add(comp);
jf.setSize(500,500);
jf.setVisible(true);
jf.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
}
pls help.
