My code is below. I have a program that compiles and works, I just have a few problems with it. the mode method isn't working, and the median doesn't work either. if the user enters 4 (to enter 4 integers) the median will be the 2 middle numbers average. so if the numbers are : 1 4 5 30, the median would be 4.5000. also, my goAgain() method doesn't work, and I dont know why. I want to ask the user if he / she wants to play again, enter y or Y for yes and n or N for no, but even if they do enter those letters, it just goes "invalid, try again" and never works right. PLEASE HELP!!! thank you
