- a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73 then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5. b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100 inclusive 10 per line.
