GitHub repo finally set
After solving some problems and reading many different guides and articles, I have finally understood how the git works and successfully set an online repo. Many thanks to Krzysztof Rosset who helped me a lot today ;)
Here you can find my Java solutions to Project Euler problems. I have also extended and debugged my Prime class. Method int getAllDivisors(long number) was added, some other bugs have been fixed. Also, the class now has a full documentation.
