防止jTextArea添加[追加arraylist时

Question

I have a JTextArea that appends an ArrayList<String> . This works well enough. But its also adding [ characters in as well. How can I prevent this?

jTextArea1.append(myarraylist.toString() + COMMA_DELIMITER + "\n");

Answer 1

You can't append the toString() of an ArrayList, unless you like the exact formatting of the toString() method of the ArrayList.

If you want custom formatting of the data you need to add each element separately by iterating through each element in the ArrayList. Something like:

for (Object text: myArrayList)
{
    jTextArea1.append(text.toString() + "...");
}
