Implement utility methods in a class ArrayUtil that:

• Compute the sum of an array of numbers, overloaded for int and double.
• Compute the average of an array of numbers, overloaded for int and double. Return 0 if the array is empty.
• Compute the min and max (as an array of length 2) of an array of numbers, overloaded for int and double. Return the appropriate MIN_VALUE or MAX_VALUE if the array is empty.
• Read all int or double from a Scanner.

Look at the unit test for details.
