For this program, you will rewrite a program you did earlier, using an array and a user-defined method instead Write a program to compute the following summation (n is input from the user) n n -1 n-2 For example, if the user enters 8 for n, then the array is 11, 2 7, 8) 1 2 3 and calculate the sum of the series 8 7 6 if the user enters 30 for n, then the array is {1, 2, 3 28, 29, 30) 1 2 3 30 and calculate the sum of the series 30 29 28 Write a method called sum that takes in an array of integers (1 to n) and returns the sum of the series above. Use the following method header public static double sum (int[] nums) Also write how this method would be called in your main method, you can name your file SumSeries Array java Check sample output on next page In the main method, prompt the user for number n, then store the integers 1 through n in an array, call the sum method to get the sum of the series and output the result
