Thread: problem with data access when a class call another class

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).
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
