The programming language required for this code is: Java. Can anyone help me asap?

The method you write should have a Javadoc comment with a description of what the method does and a @paramfor each parameter and a @return describing what information is returned. Each class should have a Javadoc with a general description and @author tag.

5. Method name: smoothArray Parameter(s): A non-null double[] with at least 3 elements in it. Return value: Returns a double[] that has as its elements a sliding average of the parameter array elements. More precisely: 1. The first and last elements of the new array are the same as the average of the first two and last two elements of the parameter array, respectively. 2. For the other elements of the new array, the element at index i , is equal to the average of elements from the parameter array at indices i-1), i, and i+1. Post-Condition: The array parameter is not changed. Example: Calling smoothArray([0.0, 0.2, 0.7, 0.2]) should return a new array [0.1, 0.3, 0.3666...,0.45] . You may see differences in your numerical values based on representational error of double numbers. Something like 0.449999999996 for 0.45 will pass the autograder tests, and is correct, even though it is unsettling to see
