Hey i need some help with my java programming, im using jgrasp to code, the problems critera is below.

Write a method sDev that accepts an array of doubles as a parameter. The sDev method should calculate and return the standard deviation of the numbers passed in by way of the array. If side calculations are needed to solve this problem, write a helper method to do so.

The equation for standard deviation is as follows:

In other words sum up ((every point - average) squared), divide by count of points -1 and square root the entire quantity.

Minor points will be deducted if all logic is in the same method. However please don't go crazy with the method creation. Only create a new method when you identify a significant standalone task that needs to be done.

Turn in one properly commented and styled java file for this part.
