Checkbox selection

Question

Hi All,
I am trying to read a text file and add the checkboxes dynamically to all the lines.This is working fine, but after checkbox is created I want to uncheck some prechecked checkboxes and save all the checked items in a arraylist but not able to do so because I am not able to access the checkbox array outside the createCheckBoxes function. Program can be run by calling this from a main method and behaviour can be seen. Not sure wat is going wrong??Please help me in this.Thankx a lot!

Answer 1

1. Learn how to correctly and consistently indent your code.
2. You are creating the array inside the loop, so it only ever has one non-null element.
