SuperClass And subclasses

Hi I am relatively new to programming and I am studying inhertance at the moment.

There is an exmaple in a book that has a class which does not extend any other class(So is it fair to say this is the superclass) also there is another class which extends this class. But what I really cant get is the class which does not extend any other class contains @Override. I thought @Override was only used in subclasses to override the superclass.

Any help would be really appreciated

The only class which does not extend any other class is Object. All other classes derive from it either directly or indirectly.

Your example with a class "which doesn't extend any other" looks something like this:

public class MyStuff {
   @Override public String toString() { return "MyStuff here"; }
}

In the above, extends Object is implied if not written. Therefore you should read it as

public class MyStuff extends Object { ... }

There are just three public methods in Object which it makes sense to override: toString, equals, and hashCode, so I assume your example uses one (ore more) of these.

In java Object class is the super class of all classes. So @Override method must be belongs to Object class methods.
