Problem reading data from textField?

Question

I have a problem in my program I'm currently doing.
I have a textArea and a textField in a container.
Inside the textArea will be displayed some questions which require user to give answers to in the textField.
When user types something in the textField and presses enter, an actionListener will trigger and take in String.
My problem is how do you wait for the user to type something in the textField?
thanks
