Input a linked list into a JTextArea

I'm trying to insert a linked list into a text area. Here is what I'm
trying with:

for(int i = 0; i < theDirectory.size(); i++) {
listArea.append(theDirectory.get(i));
}

theDirectory is a linked list of type String.

It's not working too well. I would appreciate some pointers...

Perhaps it is not. Show us your declaration code.

It should look something like this:

import java.util.LinkedList;
...

LinkedList<String> theDirectory = new LinkedList<String>( 100 );

I would expect you would want to append some sort of separator between
the strings, e.g. '\n'\ or ' ' .

"It's not working too well.".
That is rather vague. What is the compile or run time error message
you are getting? What is the unexpected behaviour?

Ideally you show a tiny complete computer program that others can run
to track problems. What you are doing is like going to the doctor's
wearing a saying a hijab saying "I'm sick. What's the matter with me?
I won't disrobe and I'm allergic to blood tests".
