Digital clock in Applet

Digital clock can be created by using the Calendar and SimpleDateFormat class. Let's see the simple example:

Example of Digital clock in Applet:

import java.applet.*;
import java.awt.*;
import java.util.*;
import java.text.*;
public class DigitalClock extends Applet implements Runnable {
Thread t = null;
int hours=0, minutes=0, seconds=0;
String timeString = "";
public void init() {
setBackground( Color.green);
}
public void start() {
t = new Thread( this );
t.start();
}
public void run() {
try {
while (true) {
Calendar cal = Calendar.getInstance();
hours = cal.get( Calendar.HOUR_OF_DAY );
if ( hours > 12 ) hours -= 12;
minutes = cal.get( Calendar.MINUTE );
seconds = cal.get( Calendar.SECOND );
SimpleDateFormat formatter = new SimpleDateFormat("hh:mm:ss");
Date date = cal.getTime();
timeString = formatter.format( date );
repaint();
t.sleep( 1000 ); // interval given in milliseconds
}
}
catch (Exception e) { }
}
public void paint( Graphics g ) {
g.setColor( Color.blue );
g.drawString( timeString, 50, 50 );
}
}

In the above example, getX() and getY() method of MouseEvent is used to get the current x-axis and y-axis. The getGraphics() method of Component class returns the object of Graphics.
