The 30 minute Introduction contains some errors: 1) Operation.added is not valid it must be Operation.Type.added 2) publc Date getDatePerformed() must be public 3) the method completed() is not implemented by the Mixing 4) the Type "K" of container is missing from the generics declaration. 5) the generic argument <M> of the Operation constructor is missing in the mixin: final Operation<M> op = new Operation<M>( item, Operation.Type.added ); 6) Calendar.roll just affects the day field not the month. So it has not the desired effect. Use Calendar.add instead. -> cal.add( Calendar.DAY_OF_MONTH, -90 );
