Answer:
Explanation:
(1).We have change the in the line number public class Factorial to public class Main so this can not effect more it depend upon the compiler
(2). we have code in line number 11 , 12 ,13 in this line we have one variable initialized n and it assign the n with entered number num and we have run while loop to till the 1 and decrease the entered value one by one and call the created function for better understanding see code
