[Solved] Getting HashMap keys / values from other method inside a same program

Question

I'm able to get the values from a HashMap and iterate it from main method.
But after I pass the HashMap to other method it doesn't work anymore.
Can anyone explain?

Thanks!
I thought it works like int x or String x as other datatype.
Didn't realize has to specify the class type as well.
