How to download a Java program into my smartphone

[Herbert]

I wrote a small Java program called ( "Hello,World )
My next step will be to install this program as an app on my smartphone and I wonder what is involved ?

Can anyone provide some hints ?

Thank you

Herbert

NB: I am a newbie and consider this a hobby.

As a hobby I do hope you still consider reading books a thing to do so you may be more informed. You can't just compile a PC Java application and dump it on a phone. You either need to make an android application using the Android SDK, or if the phone supports jME you need to make a jME application.

Yes,I do want to read books and study more.Can you recommend a good one ?

Like gimbal said, you can't just write Java and deploy it as an Android app. You have to use the Android SDK.

This is a good starting point: Getting Started | Android Developers
