How do i parse data from the second jframe back to the first?

Question

Hello.
I have a jFrame were I promt users to keep a list of Names in a jTable. (I keep data for something else, but lets say names.. ) Anyway, afterwords I want to add some extra parameters for each name. So I created a new frame, which is opened when user press an Edit button. The new frame opens and users can add for the specific name some extra data, like age, height, color, sex.. etc. that characterizes this person.
On this second form i have a save button, which when its pressed i would like to keep this information for this name, so as when user press edit again from the first frame on the same Name the data that previously entered will be loaded (lets say that the user can not enter the say name again)
I haven' t figured the code for the save Button, but with the rest I am fine.
Can you give any ideas with structures that I have to use and how the action listener will have to be??
When I set visible the new form i have made a constructor that loads the new form which have a label with the name of the person that is edited., but how do i parse data from the second form back to the first that is already opened??
Thanks very much..
