How can I write a method and force the subclasses to override this method. In Eclipse it should show in the Quick-Fix Dialog: "Add unimplemented methods".
Thanks

A subclass within the same package as the instance's superclass can override any superclass method that is not declared private or final. A subclass in a different package can only override the non-final methods declared public or protected.

Just make the method abstract. This will force all subclasses to implement it, even if it is implemented in a super class of the abstract class. Show activity on this post.
Invoking overridden method from sub-class : We can call parent class method in overriding method using super keyword. Overriding and constructor : We can not override constructor as parent and child class can never have constructor with same name(Constructor name must always be same as Class name).

Declare the method as abstract:
Eclipse will give you the "Add unimplemented methods"-option for all (unimplemented) abstract methods and interface methods.
