Write a method that computes the average of the values in an array of doubles. The header of the method is as follows: public static double average(double[] x)

Written in Java

public static double average(double[] x){

   double sum = 0.0;

   for(int i=0;i<x.length;i++){

       sum+=x[i];

   }

   return sum/x.length;

}

Explanation:

This defines the method

public static double average(double[] x){

This initializes sum to 0.0

   double sum = 0.0;

This iterates through the array

   for(int i=0;i<x.length;i++){

This adds up items of the array

       sum+=x[i];

   }

This returns the average

   return sum/x.length;

}
