1) Create a method Sum to include a FOR loop. Get a scanner and input a number form the keyboard in main(). The method will take one parameter and calculate the sum up to that number. For example, if you pass 5, it it will calculate 1+2+3+4+5 and will return it back to main() method. Main method should call the method, get the sum back, and print a sum. You call the method from main() and get the result back to main() 2) Create another method: Factorial that calculates a Product of same numbers, that Sum does for summing them up. Make sure you use FOR loop in it. 3) Make a switch that Calls either sum(...) method OR factorial(...) method, depending on what user of the program wants. Ask the user to enter a selection, after the number is entered, such as "do sum" or "do factorial", read it with the Scanner next(), then call the appropriate method in a switch.
