list of various checkboxes and textfields

i want to create a list in java, to show a various number of panels, which include a checkbox, a textfield and a button. Then i want to check if for example checkbox_1 is checked. If so, then call the number from textfield_1. I dont know how i can check explicit the textfield_1 or checkbox_1. With a for-loop i make every checkbox with same variable name. Sure you have a solution for me :)

I hope my drawing helps you to understand my question.

thanks :)
