How can I display a newline in JLabel?
For example, if I wanted:
Hello World!
blahblahblah
This is what I have right now:
JLabel l = new JLabel("Hello World!\nblahblahblah", SwingConstants.CENTER);
This is what is displayed:
Hello World!blahblahblah
Forgive me if this is a dumb question, I'm just learning some Swing basics...
You can use the MultilineLabel component in the Jide Open Source Components.

Surround the string with
<html></html>and break the lines with<br/>.You can do
and it will automatically wrap it where appropriate.
Thanks Aakash for recommending JIDE MultilineLabel. JIDE's StyledLabel is also enhanced recently to support multiple line. I would recommend it over the MultilineLabel as it has many other great features. You can check out an article on StyledLabel below. It is still free and open source.

You can try and do this:
The advantages of doing this are:
<br/>, without fail.<and>with<and>respectively, preventing some render havoc.What it does is:
"<html>" +adds an openinghtmltag at the beginning.replaceAll("<", "<").replaceAll(">", ">")escapes<and>for convenience.replaceAll("\n", "<br/>")replaces all newlines bybr(HTML line break) tags for what you wanted+ "</html>"closes ourhtmltag at the end.P.S.: I'm very sorry to wake up such an old post, but whatever, you have a reliable snippet for your Java!
JLabel is actually capable of displaying some rudimentary HTML, which is why it is not responding to your use of the newline character (unlike, say, System.out).
If you put in the corresponding HTML and used
<BR>, you would get your newlines.
