// clock runs on your system clock so updates are automatic

I got bored in lesson so i tried a bit of java and here is a fully working clock, where the time is taken from your system clock.

This is a nice clock code, but you posted it in the wrong subforum. This code is JavaScript, while this is the java subforum. This should go in the web programming subforum.

BTW: The site that you linked to also said it was Java! Maybe you should notify them.

ye

java and js are diff

but who cares?

nice code

i only just started so i presumed that they where just mutations of each other, thanks for the heads up *thumbs up*

They are actually quite different, JavaScript is a smaller language, and needs a browser to interpret it at runtime. Java is larger and more complicated, can stand alone or be incorporated into a browser, and needs a compiler to turn it into 'bytecode' for the java virtual machine to interpret. RuneScape, a popular online game, was programmed in java.

Here is the source code of a simple java clock that does the same thing that your javaScript clock does. You can see that while there are some similarities, it is actually quite different.

CODE

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.Calendar;

public class TextClock {

public static void main(String[] args) {
JFrame clock = new TextClockWindow();
clock.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
clock.setVisible(true);
}//end main
}//endclass TextClock

class TextClockWindow extends JFrame {

private JTextField timeField; // set by timer listener

public TextClockWindow() {
// Build the GUI - only one panel
timeField = new JTextField(6);
timeField.setFont(new Font("sansserif", Font.PLAIN, 48));

Container content = this.getContentPane();
content.setLayout(new FlowLayout());
content.add(timeField);

this.setTitle("Text Clock");
this.pack();

// Create a 1-second timer and action listener for it.
// Specify package because there are two Timer classes
javax.swing.Timer t = new javax.swing.Timer(1000,
new ActionListener() {
public void actionPerformed(ActionEvent e) {
Calendar now = Calendar.getInstance();
int h = now.get(Calendar.HOUR_OF_DAY);
int m = now.get(Calendar.MINUTE);
int s = now.get(Calendar.SECOND);
timeField.setText("" + h + ":" + m + ":" + s);
}
});
t.start(); // Start the timer
}
}

That looks awsome! llamatronics/crash.gif
