FOR JAVA!

Note down a program that takes as input 5 numbers and outputs mean average and standard deviation of the numbers. If the numbers are x1, x2 ,x3, x4, and x5, then the mean is :

X= ( x1 + x2 + x3 + x4 + x5 ) / 5

and the standard deviation is:

sqrt( ((x1-x)^2 + (x2-x)^2 + (x3-x)^2 + (x4-x)^2 + (x5-x)^2)) / 5)

Your program must contain at least the following methods: A system that calculates and returns the mean and a method that calculates the standard deviation.

Also format the output to 2 decimal places.
