How to output text sequentially on a JFrame?

Question

Java

I have JFrame. And I need to sequentially output lines of text to frame as a result of my program. Each entry on a new line. That is, it turns out something like a log of the application. How can I do that?

Answer 1

Link to Java text components tutorial . I have used JTextArea for similar purposes . For splitting by lines I use txtArea.getText() + '\n' + "Тест новой строки";(this is just an example).
It is not very convenient to update the entire text in front of the computer, adding a new line to the common buffer of the previous text, but there is nothing simpler in Java. You can, however, organize the elimination of previous lines so that the displayed buffer does not become too large.
