User Rating: / 6
PoorBest 

This J2ME tips illustrates the retrieval of system properties in a MIDlet. MIDlets have direct access to all four of the standard system properties defined by the CLDC specification.

import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;

/* Creates the "Hello world" program in J2ME MIDP.
Note that the class must be public so that the device
application management software can instantiate it. */

public class HelloWorld extends MIDlet
{

  public void startApp() {

    // Create a Displayable widget.
    form = new Form("Hello World");
    // Add a string to the form.
    String msg = "My first MIDlet!";
    form.append(msg);
    // This app simply displays the single form created
    // above.
    display = Display.getDisplay(this);
    display.setCurrent(form);
    printSystemProperties();

  }


/* Prints the values of the standard system properties
using the System.getProperty() call. */

  protected void printSystemProperties()
  {

    String conf;
    String profiles;
    String platform;
    String encoding;
    String locale;

    conf = System.getProperty("microedition.configuration");
    System.out.println(conf);

    profiles = System.getProperty("microedition.profiles");
    System.out.println(profiles);

    platform = System.getProperty("microedition.platform");
    System.out.println(platform);

    encoding = System.getProperty("microedition.encoding");
    System.out.println(encoding);

    locale = System.getProperty("microedition.locale");
    System.out.println(locale);
    System.out.println();
  }
}
