Here is a sample program in J2ME that demonstrates the usage of the StringItem class:
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Form;
import javax.microedition.lcdui.StringItem;
import javax.microedition.midlet.MIDlet;
public class StringItemDemo extends MIDlet {
private Display display;
public StringItemDemo() {
display = Display.getDisplay(this);
}
public void startApp() {
Form form = new Form("StringItem Demo");
StringItem hello = new StringItem(null, "Hello World!");
StringItem description = new StringItem(null, "This is a StringItem demo.");
form.append(hello);
form.append(description);
display.setCurrent(form);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
}
In this example, we create a Form object and append two StringItem objects to it. The first StringItem displays the text "Hello World!" and the second StringItem displays the text "This is a StringItem demo.". We then set the Form as the current display using the setCurrent() method of the Display object.
When this application is run on a J2ME-enabled device, it will display a screen with the two StringItem objects showing their respective texts.
