Constructor :: It very common requirement to initialize an object immediately after creation. We can define non-static methods for this purpose but they have to be invoked explicitly. Java has a solution for this requirement. Java allows objects to initialize themselves when they are created using constructors.

PROGRAM

            class Sample

            {

                        Sample( )

                        {

                                    System.out.println("Constructor called");

                        }

            }

            class ConsDemo

            {

                        public static void main(String args[ ])

                        {

                                    Sample ob=new Sample( );

                        }

            }
