Running the Car program results in the following sequence of events:
1. The new Car statement executes on line 22 of Car.java , which invokes the constructor
on line 10 of Car .
2. The call to super(4) on line 11 passes control to the Vehicle constructor on line 5,
which displays the message “ Inside Vehicle constructor ”.
3. After the Vehicle constructor returns, the instance initializer in Car on line 5 is
invoked, displaying the message “ Inside Car instance initializer ”.
4. The body of the Car constructor executes last, displaying “ Inside Car constructor ”.
Therefore, the output of main is
Inside Vehicle constructor
Inside Car instance initializer
Inside Car constructor
