[java] need help w/small program
I need to write a program that allows a user to input a number and then output the factorial. (eg. user inputs 5 and program outputs 5!=5*4*3*2*1=120) then the program has to repeat so the user can continue to enter numbers until the user enters -999. This will stop the program.
Any help would be appreciated... I'm really stuck on this one. I don't really have any experience with java.
