could anybody tell me(novice) how to use repaint method in java console programe(not in applet).when to use repaint and when to use update method and why. could u pls write me a prorgame which has a button that draw something upon being pressed on the frame. what is the problem with my following code which is a simple clock(no compile error but doesnt show the time)-
import java.util.*;
import java.text.DateFormat;
import java.awt.*;
import java.awt.geom.*;
public class Clock extends Frame implements Runnable
{
public void run() {
Thread myThread = Thread.currentThread();
while (myThread !=null) {
repaint();
try {
Thread.sleep(1000);
} catch (InterruptedException e){
}
}
}
public void paint(Graphics g) {
// get the time and convert it to a date
Calendar cal = Calendar.getInstance();
Date date = cal.getTime();
// format it and display it
DateFormat dateFormatter = DateFormat.getTimeInstance();
g.drawString(dateFormatter.format(date), 5, 10);
}
//public void update(Graphics g)
//{ paint(g) ; }
Clock(){
setBounds(300,200,200,200);
setVisible(true);
}
public static void main(String str[])
{
Clock myclock=new Clock();
Thread myThread=new Thread(myclock);
myThread.start();
}
}
Now is it OK Mr. Matthias Neumair
