Install Maven

brew install maven 

Install Akka

Creating Akka Maven Project

mvn archetype:generate 
   -DgroupId=zerofox.assessment.exercise.prime 
   -DartifactId=zerofox-assessment-exercise-prime
   -DarchetypeArtifactId=maven-archetype-quickstart
   -DinteractiveMode=false

parallel-prime design

Accepts an integer as input from the user. Creates and ActorSystem and workers within the ActorSystem and sends them a message that has the integer to be checked for "isPrime". Each worker reads the message and prints out the integer in the message if it happens to be primr. The workers are reused with new messages each time.

Compile parallel prime

mvn clean install

Add jar files to CLASSPATH

export CLASSPATH=/Users/<user>/.m2

Execute project

cd over to the directory that has pom.xml

mvn exec:java -Dexec.mainClass="zerofox.assessment.exercise.ListPrime"
