- Install Java version 1.8 for your platform from Oracle (https://docs.oracle.com/javase/8/docs/technotes/guides/install/install_overview.html).
- Install NetBeans or other integrated development environment (IDE).
- Clone a copy of the Hello World App source code from Bitbucket - https://bitbucket.org/lorainelab/hello-world-igb-app
Compile the App
Open the hello-world project in Netbeans (or your preferred IDE).
...
- Select Edit > Hello World App
- Observe a dialog appears containing the message "Hello IGB World!
Next step: Modify your code
Open the file HelloWorldIgbApp.java in the Netbeans editor. Edit the message your IGB App prints and re-build your App. Then, return to the IGB App Manager, un-install and then re-install your App. When you select the the menu item again, a dialog should appear showing your new message.
Note that you can rapidly repeat this edit-build-uninstall-install cycle. You don't have to re-build IGB or even restart it, which makes development much faster than if you had to modify the IGB code directly.
