In your main method, you will ask the user how many values they would like to enter. This value will be the size of your array of doubles.Using this value, set up a loop that will then ask the user to fill the array with doubles.Once the array is filled, you will pass the entire array into a static method that you create that will return the standard deviation of the numbers.The static method will return a double and take in your array of doubles. The following formula will be calculated using the values in the array. The static method should not have anything related to Scanner or any print lines. It simply does the math using the numbers from the passed in array and returns a single answer.(x1, x2, x3, etc, represent the numbers in the array. X with a line over it represents the average of all the numbers. N represents the number of values entered in.) Once the (unadjusted) standard deviation has been returned to the main method, print out the user’s original values and then the standard deviation.

Question

In your main method, you will ask the user how many values they would like to enter. This value will be the size of your array of doubles.
Using this value, set up a loop that will then ask the user to fill the array with doubles.
Once the array is filled, you will pass the entire array into a static method that you create that will return the standard deviation of the numbers.
The static method will return a double and take in your array of doubles. The following formula will be calculated using the values in the array. The static method should not have anything related to Scanner or any print lines. It simply does the math using the numbers from the passed in array and returns a single answer.

(x1, x2, x3, etc, represent the numbers in the array. X with a line over it represents the average of all the numbers. N represents the number of values entered in.)

Once the (unadjusted) standard deviation has been returned to the main method, print out the user’s original values and then the standard deviation. (DecimalFormat, please.)
No try/catches or loops necessary for this program.
