Explanation / Answer

You can't use compareTo with "double" array. You will need to use "Double" array. Alternatively, you can also compare directly without a compareTo "double" is a primitive data type like int. "Double" is a wrapper class for primitive data type "double" so Double d = null is valid while double d = null is invalid. Both Double d = 0 is valid while double d = 0 are valid. Double is to double as Integer is to int.
