J2ME: Identification of Location API in mobile

Before using the Location API we need to know whether the api is in the mobile or NOT.

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

public class IdentifyLocationAPI extends MIDlet implements CommandListener {
private Display mDisplay;
private Alert alert;

public void startApp() {
mDisplay = Display.getDisplay(this);
//It will return the version number
String s=System.getProperty("microedition.location.version");
alert=new Alert("Information",s,null,null);
alert.setTimeout(Alert.FOREVER);
mDisplay.setCurrent(alert);
}

public void commandAction(Command c, Displayable s) {

}

public void pauseApp() {

}

public void destroyApp (boolean unconditional) {

}
}
