Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following:the total rainfall for the year
the average monthly rainfall
the month with the most rain
the month with the least rain
Demonstrate the class in a complete program.
Input Validation: Do not accept negative numbers for monthly rainfall figures.I have the pure class for this problem and want to come out an application class which uses Scanner class to ask users to fill in their monthly rainfall.
