在JFrame中显示HTML标记或打开浏览器

Question

I am writing a Java program that creates HTML code.

What's the best/easiest possibility to have a preview of the code?

• Show the code in the JFrame : How can I do this?
• Open the windows browser with the created File? Is this possible?
• A totally different approach?

Answer 1

Both are quite easy to do. Here is a page from the Java tutorial that shows how to display HTML in Swing (you'd use a file: URL to display the contents of a file.) You can display a URL in an external browser using Java 6's Desktop class:

Desktop.getDesktop().browse(new URI("file://myfile.html"));

Alternately, save the data in a file with the *.html extension and use

Desktop.getDesktop().open(new File("myfile.html"));
