Problem statement:
Given the code for constructor overloading. What will be the output?

1. public class ConstructorCall {
2.     ConstructorCall() {
3.         System.out.println("default constructor");
4.     }
5.     ConstructorCall(int a){
6.         this();
7.         System.out.println("parameterized constructor");
8.         System.out.println(10);
9.     }
10.     public static void main(String[] args) {
11.         ConstructorCall st = new ConstructorCall(3);
12.     }
13. }

Output:

default constructor

parameterized constructor
