Scala - How to call a method on a superclass

Scala FAQ: How do I call a method on a superclass in Scala?

I was just looking at this page of how to get Scala, Android, and Eclipse working together, and at the bottom of that page they share an example of how to call a method on a superclass in Scala:

class HelloAndroid extends Activity {
  override def onCreate(savedInstanceState:Bundle) : Unit = {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.main)
  }
}

If you're not familiar with Android programming, the onCreate method is defined in the Activity class, and you typically extend that class and override the onCreate method in your class. As part of this, you always call the onCreate method of your parent class (using super in both Java and Scala), and this example code demonstrates how to do this in Scala:

super.onCreate(savedInstanceState)
