Instructions/Design: Below is a partially written program named Rainfall.java that stores the total rainfall for each of 12 months into an array of doubles and then produces output about the rainfall data. It is your job to complete the program: 1) The program should have the following 4 methods that return values: the total rainfall for the year: totalRain (returns a double) the average monthly rainfall: averageRain (returns a double) the month with the most rain: mostRain (returns an int - the index of the array) the month with the least rain: leastRain(returns an int - an index of the array) 2) In addition, the program uses (and you must write) a method that prompts the user and then stores input into the array. This method does not return any values. Name the method: initRain 3) Note: Each of the five methods you will write is public static and each takes the array as an argument. 4) The output should display only one digit after the decimal place. You must write five methods for the program. You must use an array parameter in the methods. Sample Output: Here is first run of program (program output in italics and user input in bold/italics ): Enter rain fall for month 1: 10.1 Enter rain fall for month 2: 11.2 Enter rain fall for month 3: 12.3 Enter rain fall for month 4: 13.4 Enter rain fall for month 5: 14.5 Enter rain fall for month 6: 15.6 Enter rain fall for month 7: 5.1 Enter rain fall for month 8: 6.2 Enter rain fall for month 9: 7.3 Enter rain fall for month 10: 8.4 Enter rain fall for month 11: 9.5 Enter rain fall for month 12: 10.0 The total rainfall for this year is 123.6 The average rainfall for this year is 10.2 The month with the highest amount of rain is 6. The month with the lowest amount of rain is 7.

1. Instructions/Design:
Belowis a partiallywrittenprogramnamed Rainfall.java that stores the totalrainfallfor eachof12 months into anarrayofdoubles and then
produces output about the rainfalldata. It is your job to complete the program:
1) The programshould have the following4 methods that returnvalues:
the totalrainfallfor the year:totalRain(returns a double)
the average monthlyrainfall:averageRain(returns a double)
the monthwiththe most rain:mostRain(returns anint - the indexofthe array)
the monthwiththe least rain:leastRain(returns anint - anindexofthe array)
2) Inaddition, the programuses (and youmust write) a method that prompts the user and thenstores input into the array. This method does not
returnanyvalues. Name the method:initRain
3) Note:Eachofthe five methods youwillwrite is public static and eachtakes the arrayas anargument.
4) The output should displayonlyone digit after the decimalplace.
Youmust write five methods for the program.
Youmust use anarrayparameter inthe methods.
