Problems from project euler to practice java programming and using maven to build and test projects.

To compile and run Problem 1:

mvn clean && mvn package && mvn exec:java -Dexec.mainClass="com.euler.Problem1"

• mvn clean will delete all old versions of your project (sometimes maven doesn't recompile .java files after they have been changed).

• mvn package will build (compile and jar) .java files.

• mvn exec will run .class file (might need to add a dependency to pom.xml).
