  4. Re: How do you call a method from the same non-application class?

    Are these static methods or instance methods? Is your array global or being passed from one method to the other? Hard to determine what you are doing without seeing the code or an error.
  5. Re: Beginner Coding problem in a class taught by professor with limited English comprehension

    If this is correct then your end sorted result is going to be an array with every value 1 to 10,000. Creating actual random numbers would take a long long time for this program to run. Perhaps this...

    Looks like a simple for loop to me. Google "iterative factorial algorithm" if...
