 #### Q4  What do you mean by Constructor?
     #### Constructor can be explained in detail with enlisted points:
 
-       * When a new object is created in a program a constructor gets invoked corresponding to the class.
-       * The constructor is a method which has the same name as the class name.
-       * If a user doesn’t create a constructor implicitly a default constructor will be created.
-       * The constructor can be overloaded.
-       * If the user created a constructor with a parameter then he should create another constructor explicitly without a parameter.
