I want to load large text file quickly in a JTextArea using Swing components. I tried to load a 100MB file, and it loads within seconds. But when I try to load more than a 200MB file, it takes more than 5 minutes.

How can I load large data files? For reading I use a BufferedReader and to display I use the setText() method from JTextArea.

are you setting line by line or whole text at once? – Thusitha Thilina Dayaratne Sep 12 '14 at 14:07
I read the line by line using BuffereedReader and store in StringBuilder reference then it convert into String text.Then I use textArea.setText(String text) method. – user3912886 Sep 13 '14 at 03:36
