What is the expected output?public class Profile { private Profile(int w) { // line 1 System.out.print(w); } public static Profile() { // line 5 System.out.print (10); } public static void main(String args[]) { Profile obj = new Profile(50); }}

Won't compile because of line (1), constructor can't be private
