COBCH1731 <type-name1> does not define method <method-name> of abstract class <type-name2>

A non-abstract class inheriting from an abstract class has no implementation of the specified inherited method.

In the following example, class Dog inherits from the abstract class Animal, but does not have the required implementation of the abstract method makeNoise. Add makeNoise to the Dog class for the inheritance to be satisfied.

class-id. Animal abstract.
method-id makeNoise abstract. 
end method.
end class.

class-id Dog inherits type Animal.
...
end class.
