This includes two implementations of URL parsing. I completed this as a take-home programming challenge (with a time limit of 2 hours) in October 2014.
Build the uber jar:
./gradlew shadowJar
Then run the uber jar:
java -jar build/libs/urlparser-1.0.0-all.jar urls.txt
The input to the program is a file that contains one URL to parse per line. An example file is included as urls.txt.
