Thread: Can't seem to control the checkbox

my current code is

HTML Code:

FileInputStream input = new FileInputStream(Util.getWorkingDirectory().getAbsolutePath() + File.separator + LoadTextfield.getText() + ".txt");
                BufferedReader a = new BufferedReader(new InputStreamReader(input));
                for (i = 0; i < 100; i++){
                     if (i == 5){
                        PickUpBonesCheckbox.setSelected(Boolean.valueOf(a.readLine()));
                    }

the value of a.readline() when i = 5 is true. I'm getting confused on why the checkbox isn't setting itself to true.

It works fine when i use PickUpBonesCheckbox.setSelected(Boolean.valueOf("t rue");

The purpose of the for loop is unclear. Please explain what you're doing there.
