Know your Mobile – A simple j2me application

This is a very simple code of j2me. By implementing it, and running it by your mobile device, you could learn some attributes of Java configuration of your mobile device.

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class AttributesMIDlet extends MIDlet{
private Display display;
private Command cExit;

public void startApp(){
display = Display.getDisplay(this);

cExit = new Command(“Quit”, Command.EXIT, 0);

Canvas canvas = new DummyCanvas();

Runtime runtime = Runtime.getRuntime();
Form form = new Form(“Attributes”);

form.append(new StringItem(“Know Your Mobile”, “”));
form.append(new StringItem(“Total Memory:”, String.valueOf(runtime.totalMemory()/1024)+”Kb”));
form.append(new StringItem(“Free Memory:”, String.valueOf(runtime.freeMemory()/1024)+”Kb”));
form.append(new StringItem(“n”, null));

boolean isColor = display.isColor();

form.append(new StringItem(isColor ? “Colors:”: “Grays:”, String.valueOf(display.numColors())));
form.append(new StringItem(“Width: “, String.valueOf(canvas.getWidth())));
form.append(new StringItem(“Height:”, String.valueOf(canvas.getHeight())));
form.append(new StringItem(“Repeat:”, String.valueOf(canvas.hasRepeatEvents())));
form.append(new StringItem(“Double Buff:”, String.valueOf(canvas.isDoubleBuffered())));

new CommandListener(){
public void commandAction(Command c, Displayable d){
if (c == cExit){

public void pauseApp(){
public void destroyApp(boolean unconditional){

class DummyCanvas extends Canvas{
public void paint(Graphics g){
