Chapter 1 ■ the Different faCes of Java: Create a Java 9 Development Workstation
If you want to check and see if Java 9 installed on your system simply use the same Control Panel
utility that you used in Figures 1-1 through 1-3. As you can see in Figure 1-6, the real version of Java 9.0
(not the alpha version) is now installed on my system, at 763 megabytes in size, and in my case, installed on
10/7/2017.
Figure 1-5. Install the Java 9 JDK on the workstation, accepting the default settings in the six Java 9
installation dialogs
Figure 1-6. Find the JDK-for the latest (currently 9.0.1) Java 9 version and make sure it is installed
Next, let’s install Java 8, used currently to run NetBeans 8.2 (you may already be developing using
this IDE), and also used currently to run the NetBeans 9.0 IDE (beta), which I used for this book, because
eventually Java 9 and NetBeans 9 will be used together to develop Java 9 Games. During the transition
period, NetBeans 9.0 runs on Java 8, so I am adding a section or two on how this works, for the early adopters
of the book who may use this configuration.
