my task is to create a gui for a list of cars, bus,bicycle etc. and the program should be able to add and remove to the car in store. so i wrote this code below using netbeans IDE.

But my task is to Use android environment but I dont know how to go about it. can anyone help me out?

i googled and found this link. developer.android.com

with any of these phones you have to download their SDK. They use a java like language if they are java compatible but are not exactly java as we know it from sun. I had limited experience doing this with the LG phone SDK which is also java like. The developer tool download you get with the SDK has a simulator to run your code and see a replica of a phone screen on your desktop.

@BestJewSinceJC JAva Microedition is not compatible with Android.

As adams161 pointed there is SDK for Android that can be added as plugin to Eclipse, IntelliJ IDEA or NetBeans (however there been some issues under NB, so far Eclipse has the best). Android SDK provide programming environment for you and also very functional emulator where you can test your applications without need of actual device. I have to say that this emulator is far more sophisticated then emulators provided by Java ME WTK 2.5.2 or SDK 3.0.

In general you can say that Android development is more or less of using Java API with difference here or there. On top of that lots of things can be done through XML files configurations.
Have look on some books like these which will help you. (I wanted to learn little about Android too, but so far work requirement kept me out of mobile development:( )

@BestJewSinceJC thanks but am talking about using it on eclipse and @adams161 thanks so much its was a little bit helpful and @peter_budo thanks i have already add the plugins on eclipse and now with the links to give to me am working something out...Thanks so much
