Create a Rainfall class that has the following:

one instance field which is an a double array that contains rainfall amounts for $12$ months

the constructor accepts the double array of rainfall amounts and copies it to the instance field

other methods $($which are in the chapter$)$ to:

totalRainfall that returns a double for the total rainfall for the $12$ months. There are no arguments.

avgRainfall that returns a double for the average rainfall for the $12$ months. There are no arguments.

mostRainfall that returns a double for the highest amount of rainfall for the $12$ months. There are no arguments.

leastRainfall that returns a double for the lowest amount of rainfall for the $12$ months. There are no arguments.

Your main method $($demo$)$ will create an instance of your Rainfall class passing in an array of doubles representing the rainfall amounts for $12$ months. You can ask the user for these amounts or provide them yourself. Then you will call each of the $4$ methods above and properly display the results to one decimal place.
