the output is always empty list of users

[EsraaSalem]

I finally managed to run the code by changing the packages names and other changes, but there is no outputs(I did not see the expected recommendation for each user )
this list size "List users" is always 0 it doesn't iterate to print the recommendation.
this is the code I run

Are you providing any command line input to the program?

The Hello example takes user IDs as command line parameters.

No I just run it using Eclipse. I didn't enter any inputs.
how can I enter these user IDs from Eclipse instead of command line??

Eclipse will have some kind of run configuration where you can provide parameters to use when running the application.
