Please using java
Write a program that takes its input from a text file of strings
representing numbers of type double. The program outputs to the
screen the average and standard deviation of the numbers in the
file. The file contains nothing but strings representing numbers of
type double, one per line. The standard deviation of a list of
numbers n1, n2, n3, and so forth is defined as the square root of
the average of the following numbers:
(n1 - a) 2, (n2 - a) 2, (n3 - a) 2, and so forth.
The number a is the average of the numbers n1, n2, n3, and so
forth. Hint: Write your program so that it first reads the entire
file and computes the average of all the numbers, then closes the
file, and then reopens the file and computes the standard
deviation.
