多选题 Given:
1. import java.util.*;
2. public class Garage {
3. public static void main(String[] args) {
4. Map＜String, String＞ hm = new HashMap＜String, String＞();
5. String[] k = {null, "2", "3", null, "5"};
6. String[] v = {"a", "b", "c", "d", "e"};
7.
8. for(int i=0; i＜5; i++) {
9. hm.put (k[i], v[i]);
10. System.out.print(hm.get(k[i]) + " ");
11. }
12. System.out.print(hm.size() + " " + hm.values() + "/n");
13. } }
What result is most likely?
