What will happen if you compile/run the following code?

1:  public class Q21
2:  {
3:      int maxElements;
4:
5:      void Q21()
6:      {
7:          maxElements = 100;
8:          System.out.println(maxElements);
9:      }
10:
11:     Q21(int i)
12:     {
13:          maxElements = i;
14:          System.out.println(maxElements);
15:     }
16:
17:     public static void main(String[] args)
18:     {
19:          Q21 a = new Q21();
20:          Q21 b = new Q21(999);
21:     }
22:  }

A) Prints 100 and 999.
B) Prints 999 and 100.
C) Compilation error at line 3, variable maxElements was not initialized.
D) Compillation error at line 19.
