Run the code from the directory where module-info.class is located:
C:\USERS\IBM_ADMIN\DOCUMENTS\NETBEANSPROJECTS\VIZ\BUILD\MODULES
└───viz
│ module-info.class
│
└───app
App.class
Edge.class
"C:\Program Files\Java\jdk-11.0.2\bin\java.exe" --module-path . -m viz/app.App
There should be similar output:
