Here we declare a variable called car which is a reference to an object of type Car.
Next we create a new object of type Car by using the new keyword. Here we are invoking no argument constructor of class Car. In case the car class has other constructors which take additional arguments, we could have initialized our object using the corresponding version of new.
The reference variable car is initialized then to the newly created object of type Car as described in the previous step. Now we can use the car reference variable to invoke relevant methods defined in the Car class.
