Let's add method turn
to class Car.
Run the code and we get
the message The car is turning.
We want the car to turn
left sometimes and sometimes to
turn right.
When we call the turn method,
we should pass which side to turn.
The method turn should
accept the direction of turn.
Let's change our code.
This concept of passing different
values to the same method is called
passing argument.
In this case, we can say that
method turn takes one argument.
In the previous lesson, we saw that
the method gift also takes one argument.
