Why System.out.print doesn't work with the "null" in the ternary operator?

public class Solution {
public static void main(String[] args) throws Exception {
//write your code here
int[] n = new int[15];
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int odd = 0;
int even = 0;
for (int i = 0; i < 15; i++) {
n[i] = Integer.parseInt(br.readLine());
if (i == 0) {
even += n[i];
}
else if (i % 2 == 0) {
even += n[i];
}
else {
odd += n[i];
}
}
String a = (even > odd) ? "Even-numbered houses have more residents." : (odd == even) ? null : "Odd-numbered houses have more residents.";
System.out.print(a);
}
}
