Where is the information that you want to access? What variable in what class?
In what method in what class do you want to access that information?

One way is for the class with the information...

If the data is in an array you'd use a for loop. If the data is in another kind of collection you'd probably use a while loop.

I see 2 null values that are being printed, but your there are 4 variables in the list of variables you gave???

Look at the code and see why those variables do not have valid non-null values....

Please explain your problem or ask a question.
Show the program's output and explain what is wrong with it and show what it should be.
