Add DateField with current time to a form

   <source lang="java">

import java.util.Calendar; import javax.microedition.lcdui.DateField; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Form; import javax.microedition.midlet.MIDlet; public class DateFieldTIME extends MIDlet {

 protected Display display;
 protected void startApp() {
   display = Display.getDisplay(this);
   Form form = new Form("Demo");
   form.append("line");
   DateField timeOnly = new DateField("Time", DateField.TIME);
   timeOnly.setDate(Calendar.getInstance().getTime());
   form.append(timeOnly);
   display.setCurrent(form);
 }
 protected void pauseApp() {
 }
 protected void destroyApp(boolean unconditional) {
 }

}</source>

Create DateField for Date

   <source lang="java">

import java.util.Calendar; import javax.microedition.lcdui.DateField; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Form; import javax.microedition.midlet.MIDlet; public class DateFieldSetDate extends MIDlet {

 protected Display display;
 protected void startApp() {
   display = Display.getDisplay(this);
   Form form = new Form("Demo");
   form.append("line");
   DateField timeOnly = new DateField("Time", DateField.DATE);
   timeOnly.setDate(Calendar.getInstance().getTime());
   form.append(timeOnly);
   display.setCurrent(form);
 }
 protected void pauseApp() {
 }
 protected void destroyApp(boolean unconditional) {
 }

}</source>

Create DateField for Date and Time

   <source lang="java">

import java.util.Calendar; import javax.microedition.lcdui.DateField; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Form; import javax.microedition.midlet.MIDlet; public class DateFieldDATE_TIME extends MIDlet {

 protected Display display;
 protected void startApp() {
   display = Display.getDisplay(this);
   Form form = new Form("Demo");
   form.append("line");
   DateField timeOnly = new DateField("Time", DateField.DATE_TIME);
   timeOnly.setDate(Calendar.getInstance().getTime());
   form.append(timeOnly);
   display.setCurrent(form);
 }
 protected void pauseApp() {
 }
 protected void destroyApp(boolean unconditional) {
 }

}</source>

Today"s date in DateField

   <source lang="java">

import java.util.Date; import javax.microedition.lcdui.rumand; import javax.microedition.lcdui.rumandListener; import javax.microedition.lcdui.DateField; import javax.microedition.lcdui.Display; import javax.microedition.lcdui.Displayable; import javax.microedition.lcdui.Form; import javax.microedition.midlet.MIDlet; public class J2MEDateToday extends MIDlet implements CommandListener {

 private Display display;
 private Form form = new Form("Today"s Date");
 private Date today = new Date(System.currentTimeMillis());
 private Command exit = new Command("Exit", Command.EXIT, 1);
 private DateField datefield = new DateField("", DateField.DATE_TIME);
 public J2MEDateToday() {
   display = Display.getDisplay(this);
   datefield.setDate(today);
   form.append(datefield);
   form.addCommand(exit);
   form.setCommandListener(this);
 }
 public void startApp() {
   display.setCurrent(form);
 }
 public void pauseApp() {
 }
 public void destroyApp(boolean unconditional) {
 }
 public void commandAction(Command command, Displayable displayable) {
   if (command == exit) {
     destroyApp(false);
     notifyDestroyed();
   }
 }

Use DateField
