- Now that I've created our Vehicle class,…I want to create a new class…that will inherit from the Vehicle class.…This is a process called extending the class.…We'll use the same file from the last lesson…and we're going to add onto it…with a pretty similar syntax.…The first thing that I'll do here is I will use class…SemiTruck extends vehicle.…This will make sure that the new SemiTruck…has the same properties as the vehicle,…description and wheels.…
Inside of our SemiTruck class,…we want to use constructor to create it.…Then inside of the constructor method,…we're going to use super.…So, super is going to refer back to the vehicle class…and then we can set up the properties.…So, for description, I'll create SemiTruck…and then for wheels, we'll use 18.…The next thing that we want to do here on line 26,…is we want to create a new instance of the SemiTruck.…
So, we'll say groceryStoreSemi…= new SemiTruck.…So, again, same exact syntax that we used…up there on line 16.…The next thing that we'll do is we'll use…groceryStoreSemi…
