How to output fields in an ArrayList to a JTextArea?

Question

I'm trying to do something on the lines of:

    someJtextArea.setText(String.valueOf(
    for(int i = 1; i < 0; i++)
        {
            objInstance.anArrayList.get(i).getFirstName()
        }
    ));

Answer 1

Just append to the JTextArea:

Your for loop constraints by the way are a little odd.

For example:

for (Person person: objInstance.anArrayList) {
   someJTextArea.append(person.getFirstName() + "\n");
}

(Sorry about my previous wrong answer as I initially thought that you were adding to a JTextField)
