## Shortest Java Quine with 106 chars

06.09.2007 · [Christian Ullenboom](https://tutego.de/blog/javainsel/author/admin/)

Because of a contest in a German Java forum I tried to formulate the shortest Java [Quine](http://en.wikipedia.org/wiki/Quine_(computing)):

```java
enum _{_;{String _="enum _{_;{String _=%c%s%1$c;System.out.printf(_,34,_);}}";System.out.printf(_,34,_);}}
```

To compile and run under Windows (with Unix you need to redirect Exceptions to /dev/null and use diff):

```batch
>javac _.java >java _ 2> NUL > Quine.out > fc Quine.out _.java Vergleichen der Dateien Quine.out und _.JAVA FC: Keine Unterschiede gefunden >jrunscript -e "print(new java.io.File('_.java').length())"106
```

I haven’t found a shorter solution on the net, so I suppose this is the shortest for now.
