+findFirstEvenNumber(numbers: String): int
+sumOfDigits(number: int): int
Write a class named Number Processor, which implements the interface INumberUtilities. The
class NumberProcessor implements all methods in IUtilities as below:
findFirstEvenNumber(numbers: String): int - finds and returns the first even number in the
string of numbers. If no even number is found or the string is empty/null, it returns -1.
sumOfDigits (number: int): int returns the sum of all digits in the given number. The
number can be a negative or a positive number.
Hints: You can refer to the methods: split() of the String class; abs() of the Math class.
Do not format the result.
The program output might look something like this:
1. Test findFirstEvenNumber
2. Test sumOfDigits
Enter Test Case No. (1/2): 1
Enter a string of numbers: 3 5 7 9 10 12 14
1. Test findFirstEvenNumber
2. Test sumOfDigits
Enter Test Case No. (1/2): 2
Enter a number: -987
