Write a program that uses nested loops to collect data and calculate the average rainfall over period of years.

1. The program has a method named getYear to ask the user to enter the number of years and return the number. (Input validation: Do not accept numbers less than 1 for the number of years)

2.The program has a method named getRainfall to ask the user to enter the number of inches of rainfall for a month and return that number. (Input validation: Do not accept negative numbers for the rainfall)

3. The program has a method named calcAvgRain to calculate and return the average monthly rainfall over a period of years. It accepts the number of years as argument. The method uses a nested loop to collect the rainfall for those many years. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will call the getRainfall method to get the rainfall for that month. After all iterations, the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
