How can one complete the FizzBuzz exercise in Codingbat with just a return statement?

The code that I last used to solve the problem was:

public String[] fizzBuzz(int start, int end) {
String[] a = new String[end - start];
for(int i = start; i < end; i++) a[i - start] = i % 15 == 0 ? "FizzBuzz" : i % 3 == 0 ? "Fizz" : i % 5 == 0 ? "Buzz" : String.valueOf(i);
return a;
}

My goal is to have code that looks like this:

public String[] fizzBuzz(int start, int end) {
return foo;
}

Problem

This is slightly more difficult version of the famous FizzBuzz problem which is sometimes given as a first problem for job interviews. (See also: FizzBuzz Code.) Consider the series of numbers beginning at start and running up to but not including end, so for example start=1 and end=5 gives the series 1, 2, 3, 4. Return a new String[] array containing the string form of these numbers, except for multiples of 3, use "Fizz" instead of the number, for multiples of 5 use "Buzz", and for multiples of both 3 and 5 use "FizzBuzz". In Java, String.valueOf(xxx) will make the String form of an int or other type. This version is a little more complicated than the usual version since you have to allocate and index into an array instead of just printing, and we vary the start/end instead of just always doing 1..100.

Test Cases

fizzBuzz(1, 6) → ["1", "2", "Fizz", "4", "Buzz"]
fizzBuzz(1, 8) → ["1", "2", "Fizz", "4", "Buzz", "Fizz", "7"]
fizzBuzz(1, 11) → ["1", "2", "Fizz", "4", "Buzz", "Fizz", "7", "8", "Fizz", "Buzz"]
fizzBuzz(1, 16) → ["1", "2", "Fizz", "4", "Buzz", "Fizz", "7", "8", "Fizz", "Buzz", "11", "Fizz", "13", "14", "FizzBuzz"]
fizzBuzz(1, 4) → ["1", "2", "Fizz"]
fizzBuzz(1, 2) → ["1"]
fizzBuzz(50, 56) → ["Buzz", "Fizz", "52", "53", "Fizz", "Buzz"]
fizzBuzz(15, 17) → ["FizzBuzz", "16"]
fizzBuzz(30, 36) → ["FizzBuzz", "31", "32", "Fizz", "34", "Buzz"]
fizzBuzz(1000, 1006) → ["Buzz", "1001", "Fizz", "1003", "1004", "FizzBuzz"]
fizzBuzz(99, 102) → ["Fizz", "Buzz", "101"]
fizzBuzz(14, 20) → ["14", "FizzBuzz", "16", "17", "Fizz", "19"]
