Write a Java method that takes a one dimensional array of doubles as a parameter. The method returns the absolute difference between the sum of numbers lower than the value in the middle of the array and the sum of numbers higher or equal to the middle value. Write a program to test your method.

Note: When the array length is even, the middle value is the average of the two values in the middle.

Use the following arrays to test your program:

Case #1, the length of array is odd: [8.5 32.8 27.2 19.1 6.5 17.6 24.2 23.1 20.6 13.2 28.4 14.7 18.6], for this case your program should output: 29.30

Case #2, length of array is even: [8.5 32.8 6.2 19.1 15.5 17.6 12.2 3.2 28.4 14.7], for this case your program should output: 37.60
