Please advise me on Java mobile app [closed]

Question

I am new to Java and I want to create a Java app for mobiles. When I approached software companies they asked for "Android / Blackberry / Symbian" etc...

Being a newb, I am really surprised by these questions. Can you please tell me whether there are any other mobile platforms in Java?

Are Blackberry apps and Java mobile apps different? And what is the target phone for j2ME applications?

Answer 1

Java ME is waning.

iPhone is Objective-C; there's no Java on iPhone.

Android is its own platform, different from Java ME.

BlackBerry used to be based on Java ME, but they're moving in an HTML/CSS/JavaScript direction, away from Java ME.
