Simple programming exercise from long ago found in deep dark laptop folder.
Recombines fragments of a string that are delimited by ':'. Each line of test.txt is a single test case.
Running
Run from the command line like... :
cd src
java string.recombination.RecombinatorApplication.java
java string.recombination.StringRecombinator.java
javac string.recombination.StringRecombinator ../test.txt
Or you could (should) be a bit more clever than that ;)
