Is there any compiler error in the below Java program?

class Point {
    int m_x, m_y; 
    public Point(int x, int y) {    m_x = x;    m_y = y;  }
    public static void main(String args[]) 
      Point p = new Point();

(A) Yes
(B) No

Answer: (A)

Explanation: The main function calls paramaterless constructor, but there is only one constructor defined in class which takes two parameters.

Note that if we write our own constructor, then compiler doesn’t create default constructor in Java. This behavior is same as C++.
