Program standard deviation calculator

You should have checks at the top of your mean and SD functions to see if the length of the array is 0. Otherwise, you could divide by 0. Now, this won't be a problem with your code because you force 10 inputs from the user, but in general, this is good practice. Improve this answer. Michael Yaworski Michael Yaworski Thank you for the input. The only reason why I have a static array is because the assignment that I am completing this for calls for an array of ten.

I also understand that the for loops are in different scopes, but for my own clarity I just prefer to use different variables. But as a general concept, there's no reason to limit the length of the array. It should work for any array size. But what makes you think there's an error in your code? Reference Materials string.

Now, in order to iterate through the array, we need to find the size of the array.

Now, use the for-loop and iterate through this array and increment it by 1 as we need to print all the elements of the array. Then, again use the for-loop and iterate through the array in order to calculate the sum of the elements of the array. Now, the standard deviation will be calculated with the help of mean, which is done by iterating through for-loop again and with the help of Mathematical predefined methods like Math.

After that, the value will be returned by that class and then print. Attention reader! Get hold of all the important Java Foundation and Collections concepts with the Fundamentals of Java and Java Collections Course at a student-friendly price and become industry ready.
