Use JTextField to List items

I'm not too familiar with Java GUI programming, and I wanted to do something where I have a loop that spits out a list of stuff and have the JTextField render it in the order it comes out.

I just do not know how the second parameter of the JTextField insert() function works. Right now when I do something like:

for(int i = 0; i < list.size(); i++){
    textArea.insert(list.get(i), 0);
}

It does what I want, except it lists everything in backwards order that I put it in. I want it to display everything the other way around.

Thank you for any advice.

All you need to define a temporary string, result and for every item in the list add the string representation to that variable. When you have looped through everything, all you need to do is textArea.setText(result).

String result = "";    
for(int i = 0; i < list.size(); i++)
{
    result += list.get(i).toString();
}

textArea.setText(result);
