Implement your own Shark ASAP application (5 of 5)

Implement a GUI

You tested your application and you are going to implement a user interface. Congratulations.

We strongly suggest to follow the mode-view-control idea. You implemented and tested a control and most probably (parts of) a model. It is a pure Java program until now. That’s brilliant. It is easier to test and very portable.

Produce a jar

You should handle your code as a library that is used in your GUI environment. Create a jar for that reason. Most IDE will help. The follow lines in a command line interface would do the same, though.

cd target/classes
jar -cf YourComponent.jar net
move YourComponent.jar <yourArtficatFolder>/YourComponent.jar

Go to your class folder. Create a jar with all your classes. Use this jar as a library e.g. in Android.

Now, you chose an environment to implement a user interface. We work mostly with Android, see section Go Android.
