How to correctly redirect the output of the streams to a TextArea?

Question

Java

I have two running threads (they must work a certain number of times), which periodically print some information, for example - System.out.println("I am Thread-0"). If I immediately display it in a TextArea, then when I enter a number greater than 8 (this is how many times they have to work), the program ends with errors. So what's the best way to send information to a TextArea?

Answer 1

Synchronize threads with javafx thread.
