Source Code For the simple TIME program

Main Class : ExeTest.java

package exetest;
public class ExeTest {
public static void main(String[] args) {
MyFrame m = new MyFrame();
m.setVisible(true);
 }
}

JFrameForm Class : MyFrame.java

package exetest;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class MyFrame extends javax.swing.JFrame {

int timeRun = 0;
int heur,minute,second;

public MyFrame() {

initComponents();
Update_time();

}

private void Update_time() {

new Thread() {

public void run() {

while (timeRun == 0) {

Calendar cal = new GregorianCalendar();

int month = cal.get(Calendar.MONTH);
int year = cal.get(Calendar.YEAR);
int day = cal.get(Calendar.DAY_OF_MONTH);

//date.setText((day) + "/" + (month + 1) + "/" + (year));

second = cal.get(Calendar.SECOND);
minute = cal.get(Calendar.MINUTE);
heur = cal.get(Calendar.HOUR);
int AM = cal.get(Calendar.AM_PM);
String day_night = "";
if (AM == 1) {
day_night = "AM";
} else {
day_night = "PM";
}
jLabel2.setText((heur) + ":" + (minute + 1) + ":" + (second) + " " + day_night);
}
}
}.start();
