⁠To compile the project

git clone https://github.com/alonsoir/stream-java8-test.git⁠
mvn clean package

⁠To show Euromillions and primitiva in local mode

java -cp target/MyStreamjava8-1.0.jar com.aironman.ApiStreamTests all 80 PATH_TO/Euromillones2004_2018.csv PATH_TO/primitiva.csv.

80 means the number of iterations, 80 predictions.

⁠To show only Euromillions

java -cp target/MyStreamjava8-1.0.jar com.aironman.ApiStreamTests em 80. 80 means the number of iterations, 80 predictions.

⁠To show only primitiva

java -cp target/MyStreamjava8-1.0.jar com.aironman.ApiStreamTests primitiva 80. 80 means the number of iterations, 80 predictions.

Done. Time duration: 0 secs.

It will generate two files, final_output_star_martes\,\ \ 4\ de\ diciembre\ de\ 2018\,\ 13\:18\:13\ CET.txt
and final_output_winners_martes\,\ \ 4\ de\ diciembre\ de\ 2018\,\ 13\:18\:13\ CET.txt.
The name of the files is created using the pattern final_output_winners_$actual_date.txt and final_output_star_$actual_date.txt
$actual_date is the actual date using unix format.

100 means the number of iterations, 100 predictions.

⁠Dependencies

The Project needs maven, java8 to compile and run the jar, some unix commands to run the script and docker if you want to run a container:
tr
sort
uniq
awk

I think these unix commands come by default in osx and I think they also come by default in linux, not sure in windows.
