I need to understand how to pass data gathered in one .java file to another.java file.
For instance, I ask a user for their name and age. The I want to send the name and agae variable to another .java file to compute their birth day by subtracting their age from the current year. I then want to send the data bak to the first .java file to output the birth year.
I know I need to use instantiation, but I don't know where or how.
Any help would be appreciated.
Thanks.

Why do you need to use two different classes to solve this problem? Is this an assignment?

This question is in reference to a assignment. My specific example is not part of the assignment but just the type of assignment.
I essentially as supposed to pass data from one .java file to another. THe variables have to be gathhered in the first file and computed in the second?
THanks.

I really don't know the answer, I just played around with this - using the constructors to pass info - and it seems to work OK, but I don't know if there are any pitfalls doing it this way
 
What do you have to say for yourself? Hmmm? Anything? And you call yourself a tiny ad.
