Constructor and Destructor

Answer:

Constructor:
-----------------

1. The Constructor is the first method that is run when an instance of a type is created. In visual basic a constructor is always Sub new ().

2. Constructor are use to initialize class and structure data before use. Constructor never returns a value and can be overridden to provide custom initialization functionality.

3. The constructor provides a way to set default values for data or perform other necessary functions before the object available for use.

Destructor:
---------------
Destructors are called just before an object is destroyed and can be used to run clean-up code. You can’t control when a destructor is called.
