Java (as of 7) doesn't support HERE docs (also known as multiline strings) unfortunately.

If you're trying to accomplish templating, there are a few options:

These aren't exactly similar to HERE docs in Perl or PHP since the string that describes the template isn't directly in your code; it's usually in a separate file.

There was a proposal put forward by Stephen Colebourne as well as a proposal via Project Coin, neither of which made it into Java 7, which was a little disappointing. Languages like Groovy and Scala, which also run on the JVM do support multiline strings.

May be supported by Java 7. I confirm that a dead end in Java 6. – Renaud Nov 02 '11 at 18:14

@Renaud They didn't make it into 7. There was a proposal for it, but it didn't make it in. Hopefully in 8. – Vivin Paliath Nov 02 '11 at 18:17

Crazy Java. I have to stick with this then at-least. http://stackoverflow.com/questions/878573/java-multiline-string/878704#878704 – Nov 02 '11 at 18:21
@VivinPaliath: Arf… Thanks for the precision… – Renaud Nov 02 '11 at 18:23
@Google Yes, unfortunately :( Renaud No worries. I was pretty disappointed that it didn't make it in. – Vivin Paliath Nov 02 '11 at 18:24

In the meantime if you find it useful here's a basic swing application I use to do this for SQL that's embedded into the classes. I find myself using it over and over again so why not share it?

(a small note, its throw away code since I put it together in a week where I needed to rapidly format queries, I might clean it up at some point)
