Write a program to calculates the standard deviation, MATLAB Programming

Write a program that reads in numbers (of type double) from a file, stores them in an array, and then calculates the mean, variance, and standard deviation.  

Your program should solve the problem by using the following methods implemented in a class..named Calculate.java  

This class should implement the following methods:

1.  One method to count the number of data numbers in the input file. This method should:

o  be public and static

o  be named  countData

o  accept a String representing the filename

o  return an integer that represents the number of numbers in the data file

2.  One method to read the numbers and the data file. This method should:

o  be public and static

o  be named  readData

o  accept a String representing the filename, and a parameter for an array of type double

3.  One method to calculate the mean value

This method should:

o  be public and static

o  be named  calMean

o  accept an array of type double

o  return the calculated mean as a number of type double

4.  One method to calculate the variance

This method should:

o  be public and static

o  be named  calVariance

o  accept an array of type double and the calculated mean value as a double

o  return the calculated variance as a number of type double
