How can I display red text in a JTextArea?

Question

I want to show error(text) in result in red color after compiling exec file and display it in textarea of gui using swing in java.

Answer 1

A normal JTextArea doesn't support fancy things like different colors of text. However, there are similar components that do. See http://java.sun.com/docs/books/tutorial/uiswing/components/text.html

Answer 2

JEditorPane can get content formatted in HTML. The official Sun tutorial also gives some insight:

The JTextArea class provides a component that displays multiple lines of text and optionally allows the user to edit the text. If you need to obtain only one line of input from the user, you should use a text field. If you want the text area to display its text using multiple fonts or other styles, you should use an editor pane or text pane. If the displayed text has a limited length and is never edited by the user, use a label.
