 small sudoku solver in java. Not completely optimized but still finished all sudokus in the tests in less than a second.

Does not use newer java features so it will probably work from at least java 1.6. Does not depend on external libraries outside standard java classes.

Usage:

javac sudoku.java
java sudoku line line line line line line line line line

each line consists of 9 characters of the set .123456789

all possible solutions are printed
