How to make messages appear one below the other in chat in Java?

Question

Java

Hello. I'm writing a Java application in Swing, how can I make the messages appear one below the other?
Example:
Jimm: Hi.....
Kim: Hi...
Thanks in advance!

Answer 1

If, according to the condition of the problem, we must telepathically find out what, where and how exactly is displayed in this application, then I would venture to offer an answer: we need to add a "line feed" to the end of the added line.
You can do it like this (correctly):
or like this (obviously):
myJTextArea.append(myString + "\n");
