1010: Fixed the two remaining SonarCloud errors (iluwatar#1023)

The two remaining files were still creating a Random everytime the method
was called. These were missed in the previous commit because the previous
commit had fixed only one of the methods; in other words, there were
multiple methods that were creating the Random object on each call.
