I don't know this but I'll ask Chatgpt. Its better than you getting no answer at all.

In Java 2 Micro Edition (J2ME), you can implement auto-scrolling text by using the Ticker class and attaching it to a Form or Alert. The Ticker class is used to display scrolling text, typically for notifications or updates. Here's how you can achieve auto-scrolling text in your J2ME application:

import javax.microedition.lcdui.*;

public class AutoScrollingText extends MIDlet {

private Display display;
private Form form;
private Ticker ticker;

public AutoScrollingText() {
display = Display.getDisplay(this);
form = new Form("Auto-Scrolling Text" wink

;
ticker = new Ticker("This is some auto-scrolling text. It will keep scrolling to the left." wink

;
form.setTicker(ticker);
}

public void startApp() {
display.setCurrent(form);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}
}

In this example:

We create a J2ME MIDlet class called AutoScrollingText.

Inside the constructor, we create a Form named form and a Ticker named ticker. We attach the ticker to the form using the setTicker() method. The text provided to the Ticker constructor will be automatically scrolled.

In the startApp() method, we set the form as the current display to make it visible.

The pauseApp() and destroyApp() methods are left empty as placeholders.

You can adapt this code to your J2ME application's "About" menu or any other screen where you want to display auto-scrolling text. Simply create a new Form for your "About" menu, set the Ticker with your desired text, and attach it to the Form.

Remember that J2ME is an older technology, and its capabilities are limited compared to modern mobile development platforms. Therefore, the user experience for auto-scrolling text may not be as smooth or customizable as in more modern mobile app development frameworks.

Pls don't ask me to explain it! I don't know java with J2ME.

I hope the code gives you an insight on what you are doing.

You can incorporate the code in your program and try it

Thanks for trying to help
i know about ticker i always use it in my code.
but what i'm asking is the one that will make a text to move upward.for example,all the post we've posted to be scrolling by it self without be swipe up by anyone.
another example, when they finish any movie or film,you know that the name of the actors will be going up by itself?that's what i mean by text auto-scroll.i always see it in gameloft game when i went to the about menu,it be will lyk when they finish movie.
and i want to add it to my code also

What are you using ? LWUIT or Form, I did J2ME in the past, kinda surprised you're writing it, I should be able to assist to a degree, if it's LWUIT, if you can calculate the height of the Layout, and within an elasped time, render the text by the Y coords till the text is off the screen, then you can destroy, paste more of this if you can.

Both form and lwuit for the phone, but with Form you cannot edit it, you can't do much customization to it, that is why people use LWUIT, you can use codenameone or Nokia LWUIT if they still exists, I started with Codenameone then I moved to Nokia LWUIT for development. let me know how it goes.

All J2ME libraries are in jar, use that but it has it's own documentation. Curious why are you building a J2ME app in 2023 ?

I'm old , I wrote J2me back then at CCHUB, I was part of Efiko, so Nokia contracted Futurice to teach us Java and bootstrap our ideas, I was like 21 or so. But I enjoyed it, I learnt alot about J2Me and Canvas that time.

It's Canvas just like in HTML5, but one of the constestant build a danfo nokia game, and it was all Bitmap and spritesheet. We used Canvas also but ours was to build the UI, Nokia wrote the library. It's basically Swing/AWT inspired but for MIDP phone.
