When to use super class method in subclass without override? is it possible?

Question

I'm new to android. According to the code below, if onListItemClick is a super class method, then why override is not used? and if it's a subclass method, then why when i change the method name, app crashes?!

class BasicViews5Activity extends ListActivity{

    //onCreate method here

public void onListItemClick(ListView parent, View v, int position, long id){
   //some code here
}
}

The class ListActivity contains a method

 protected void onListItemClick (ListView l, View v, int position, long id)

Therefore, your own implementation of that method in a class inheriting from ListActivity overrides the super class method.

In JAVA (and Android), the @Override annotation is optional. Have a look at this question to find out more about the annotation and when to use it (short answer: always use @Override).
