Java SE (Java Platform, Standard Edition)

Hello,

the snipped below read a buffer reader input and prints the output to the system out and appends a JTextArea.

While the debug output on the console updates as the lines get read the JTA effectively "freezes" until after the loops finished. Any idea how to redraw/sync the JTA with the console update so that it shows as "being updated"?

Many thanks,

R.

while (true) {
                String line = br.readLine();
                if (line == null) {
                    break;
                }
                System.out.println(line);
                out.appendJTA(line + "\n");
                
            }
