How to continuously add objects to array list with button(actionListener) ?

I finally managed to get my GUI setup, and the listeners registered. I have a Student class, a StudentDemo class, and a StudentInfoWindow.

In the StudentInfoWindow class i have a addButton, when i click it, it grabs the info from the text fields, creates a student object, adds it to an array list, and finally clears the text fields. I would like to keep on adding Objects/elements to the array list every time i hit addButton.

I can't get around the idea, i think i should have a boolean variable isAdding, to keep track of when i should stop adding elements, but i cant even add multiple ones to begin with.

Computing is a discrete word; nothing is continuous. :-)
The problem of adding listeners is unclear. Just add them. Frankly, I feel it would be awkward to post the same reference I did in response to your previous question. :-)

uuughhhhhh i found out what i was doing wrong, i created the array list inside the method instead of outside, so every time i was creating a new array list. sorry, i didnt mean to ask the question and then answer it my self. thanks again!

I was creating the array list inside the actionPerformed method, so i was recreating a new list every time i click the button. Instead i created the array list at the top of the class, so it just keeps on adding objects!
