Abstract Methods
Ib qho abstract method has no implementation. Nws tsuas muaj ib txoj kev kos npe. Ib yam li cov txheej txheem hauv Java interface. Yog hais tias ib chav kawm muaj ib txoj kev paub daws teeb meem, tag nrho cov chav kawm yuav tsum tau tshaj tawm tias abstract.
Cov chav kawm paub daws teeb meem puas tau siv lub cev?
Txoj kev paub daws teeb meem tsis tuaj yeem muaj lub cevCov chav kawm Abstract tuaj yeem muaj cov teb zoo li qub thiab cov qauv zoo li qub, zoo li lwm cov chav kawm. … Cov chav kawm Abstract tsis tuaj yeem muaj txoj hauv kev zoo li qub. Yog tias ib chav kawm txuas ntxiv chav kawm paub daws teeb meem, ces nws yuav tsum txhais tag nrho cov kev paub daws teeb meem (override) ntawm cov chav kawm paub daws teeb meem.
Yuav ua li cas paub daws teeb meem yuav tsum tau ua C?
Txoj kev paub daws teeb meem, zoo ib yam li cov txheej txheem hauv kev sib cuam tshuam, tau tshaj tawm yam tsis muaj kev siv. Lawv tau tshaj tawm nrog lub hom phiaj kom muaj cov menyuam hauv chav kawm muab kev coj ua. Lawv yuav tsum raug tshaj tawm hauv chav kawm paub daws teeb meem.
Yuav ua li cas paub daws teeb meem siv qhov cuam tshuam?
Java Abstract chav kawm tuaj yeem siv qhov cuam tshuam yam tsis muajtxawm tias muab kev siv cov txheej txheem cuam tshuam. Java Abstract chav kawm yog siv los muab txoj hauv kev siv rau txhua qhov subclasses lossis muab kev siv ua ntej.
