Java Program to Illustrate Use of Chaining Constructor

This is a Java Program to illustrate the use of chaining of constructor.

Calling of one constructor from another constructor with respect to current object is constructor chaining. It can be achieved in any order.

Here is the source code of the Java Program to illustrate the use of chaining of constructor. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. public class Constructor_Chaining
  2. {
  3.         public Constructor_Chaining
  4.         {
  5.             System.out.println("In default constructor");
  6.         }
  7.         public Constructor_Chaining(int i)
  8.         {
  9.             this();
  10.             System.out.println("In single parameter constructor");
  11.         }
  12.         public Constructor_Chaining(int i,int j)
  13.         {
  14.             this(j);
  15.             System.out.println("In double parameter constructor");
  16.         }
  17.         public static void main(String a[])
  18. 		{
  19.            Constructor_Chaining obj = new Constructor_Chaining(11,12);
  20.         }
  21. }
