Explanation / Answer
Problems with the code :
1. First of all, You cannot have 2 public classes in a single file, because that would defeat the whole purpose of having spreading a program into modules. Delete the "public" keyword from one of the classes to fix this issue.
Let's say delete "public" from "public class Month" i.e change it to "class Month" only.
2. Lines causing error are:
Month m3 = new Month(Month.MARCH);
Month m4 = new Month(Month.DECEMBER);
these lines are in the FIRST part of the code
change them to :
Month m3 = new Month("MARCH");
Month m4 = new Month("DECEMBER");
as the constructor defined in the Month class takes input as string.
Make the changes I proposed in above two points and your program will then run fine.
If you want the modified file , I'm giving posting the dropbox public link
