C# thiab. NET kev xam phaj cov lus nug: -Dab tsi yog qhov txawv ntawm chav kawm paub daws teeb thiab interface?
| Abstract chav kawm | Interface | |
|---|---|---|
| Kev tshaj tawm txawv txav | Peb tuaj yeem tshaj tawm cov kev hloov pauv | Hauv interface peb ua tsis tau li ntawd. |
| Inheritance vs Implementation | Cov chav kawm Abstract muaj qub txeeg qub teg. | Interfaces yog siv. |
Hauv qhov no, dab tsi yog chav kawm paub daws teeb meem hauv C #?
Ib chav kawm abstract yog hom tshwj xeeb ntawm chav kawm uas tsis tau instantiated. Ib chav kawm abstract yog tsim los kom tau txais txiaj ntsig los ntawm subclasses uas yog siv los yog override nws txoj kev. Koj tuaj yeem muaj kev ua haujlwm hauv koj chav kawm abstract - cov txheej txheem hauv ib chav kawm abstract tuaj yeem yog ob qho tib si abstract thiab pob zeb.
Tsis tas li ntawd, qhov txawv ntawm chav kawm abstract thiab interface C # yog dab tsi? Hauv C# , ib Interface tsuas yog muab cov kev pabcuam pej xeem uas tau tshaj tawm nyob rau hauv lub interface ,ua ib chav kawm abstract muab cov kev pabcuam pej xeem tau hais tseg hauv chav kawm paub daws teeb meem thiab cov tswv cuab uas tau txais los ntawm cov abstract chav kawm puag chav kawm.
Qhov thib ob, lub hom phiaj ntawm chav kawm paub daws teeb meem hauv C # yog dab tsi?
Cov lub hom phiaj ntawm ib chav kawm abstract yog los txhais qee tus cwj pwm uas tuaj yeem tau txais los ntawm ntau lub subclasses, tsis tas siv tag nrho chav kawm . Hauv C# , cov abstract lo lus tseem ceeb xaiv ob qho tib si chav kawm abstract thiab ib txoj kev ntshiab virtual.
Lub hom phiaj ntawm chav kawm abstract yog dab tsi?
Ib Java chav kawm abstract yog a chav kawm uas tsis tuaj yeem instantiated, txhais tau tias koj tsis tuaj yeem tsim cov xwm txheej tshiab ntawm ib qho chav kawm abstract . Cov lub hom phiaj ntawm ib chav kawm abstract yog ua raws li lub hauv paus rau subclasses. Qhov no Java chav kawm abstract kev qhia piav qhia yuav ua li cas chav kawm paub daws teeb meem yog tsim nyob rau hauv Java, cov cai dab tsi siv rau lawv.
