JAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method.   Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2   Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average.  If the number of elements in an array is odd don't modify the last number of the array.   Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…
