It can be seen from Figure 5.6 that the Java JDK 14 has been installed with the NetBeans IDE 12 and located in the Libraries folder in this project. If you want to use other software develop-ment kits (SDK), the Joko another project or library with your projects, you can load them first, then add them into your library by right-clicking on the Libraries node and selecting the associated operational menu item from the popup menu.
Next we need to add a graphical user interface with other necessary GUI components to our project and use it as a user interface to communicate with our project during project runs.
