Problem to access data when a class calls another class

[ea09530]

Hello everybody,
I am new to java and I can not finish this exercise.

I have a timer (Prog1) that calls an Employee Report (Prog2).
The forum gave me the answer how Prog1 can can call Prog2.
For every tick of the timer (Prog1), how can I double the value of the field basic_salary (Prog2)????
Any help/advice/hints to this would be valuable to me becuase I dont know how to fight it. Thanks. Michael

      // construct a timer that calls the listener
