Using `super` in a Child's Method

The toString() method in the child class Movie is nearly the same as the one in Video.

Often (as in the example) you want a method in a child class that adds features to a method in a parent class. You can use the super reference in this situation. For example, here is Video's method:

public String toString()
{
  return getTitle() + ", " + getLength() + " min. " ; 
}

Here is Movie's method without using super:

public String toString()
{
  return getTitle() + ", " + getLength() + " min. available:" + getAvailable() +
         " dir: " + director + ", rating:  " + rating ; 
}

Movie's method would better be written using super:

public String toString()
{
  return super.toString() + " dir: " + director + ", rating: " + rating ;  
}

Unlike the case when super is used in a constructor, when super is used in a method it does not have to be the first statement.
