  Constructors:          *  Constructor is a special type of method which is executed automatically when an object is created.          * Constructor  cannot be called using CALL METHOD.          *  Constructors are methods with a predefined name.         * Multiple CONSTRUCTOR and CLASS_CONSTRUCTOR are not allowed with in a class.   Types of constructors: * There are two types of constructors . * Instance constructor.     - Method name - CONSTRUCTORS.     - It has only imported  parameters.     - It can access  both instance and static attributes.     - It is called every time when object is created. * Static constructor.      - Method name - CLASS_CONSTRUCTORS.     - It does not have any parameters.     -  It can access  static attributes.   ...
