Lub hom phiaj tseem ceeb ntawm kev paub daws teeb meem yog zais cov ntsiab lus tsis tsim nyog los ntawm cov neeg sivAbstraction yog xaiv cov ntaub ntawv los ntawm lub pas dej loj dua los qhia cov ntsiab lus ntawm cov khoom rau tus neeg siv. Nws pab txo cov programming nyuaj thiab kev siv zog. Nws yog ib lub ntsiab lus tseem ceeb ntawm OOPs.
Dab tsi yog abstraction thiab vim li cas peb siv nws?
Abstraction tsuas yog tshem tawm cov ntsiab lus tsis tsim nyogLub tswv yim yog tias tsim ib feem ntawm txoj haujlwm nyuaj, koj yuav tsum txheeb xyuas qhov twg ntawm qhov ntawd lwm tus yuav tsum paub txhawm rau tsim lawv qhov chaw, thiab cov ntsiab lus dab tsi koj tuaj yeem nkaum. Qhov uas lwm tus yuav tsum paub yog qhov abstraction.
Dab tsi yog abstraction vim li cas nws thiaj xav tau hauv kev ua haujlwm?
Abstraction yog siv los zais cov ntaub ntawv keeb kwm yav dhau los lossis kev siv tsis tsim nyog ntawm cov ntaub ntawv kom cov neeg siv tsuas pom cov ntaub ntawv xav tauNws yog ib qho tseem ceeb tshaj plaws thiab tseem ceeb ntawm cov khoom- oriented programming. Cov haujlwm ua ntej txhais tau zoo ib yam li cov ntaub ntawv abstraction.
Lub luag haujlwm ntawm kev xav yog dab tsi?
Abstraction (los ntawm Latin abs, lub ntsiab lus deb ntawm thiab trahere, lub ntsiab lus kos) yog txheej txheem ntawm kev tshem tawm lossis tshem tawm cov yam ntxwv ntawm qee yam txhawm rau txo nws mus rau txheej txheej ntawm cov yam ntxwv tseem ceeb… Abstraction muaj feem xyuam rau ob qho tib si encapsulation thiab cov ntaub ntawv zais.
piv txwv abstraction yog dab tsi?
Nyob hauv cov ntsiab lus yooj yooj yim, abstraction " displays" tsuas yog cov yam ntxwv cuam tshuam ntawm cov khoom thiab " nkaum" cov ntsiab lus tsis tsim nyogPiv txwv li, thaum peb tsav tsheb, peb tsuas yog txhawj xeeb. hais txog kev tsav tsheb zoo li pib / nres lub tsheb, nrawm / tawg, thiab lwm yam.… Qhov no yog ib qho piv txwv yooj yim ntawm abstraction.
