Cov ntaub ntawv zais yog txheej txheem uas ua kom cov ntaub ntawv tshwj xeeb nkag mus rau cov tub kawm thiab muab cov khoom ncaj ncees los ntawm kev tiv thaiv kev hloov pauv tsis xav tau lossis xav tau. Abstraction, ntawm qhov tod tes, yog ib qho OOP lub tswv yim uas zais cov ntsiab lus ntawm kev sivthiab qhia txog kev ua haujlwm rau tus neeg siv xwb.
Puas yog cov ntaub ntawv zais thiab encapsulation tib yam?
Cov ntaub ntawv zais tau tsom mus rau kev nkag tau ntawm cov khoom siv hauv chav kawm, thaum cov ntaub ntawv encapsulation tsom mus rau seb cov ntaub ntawv nkag mus li cas thiab cov khoom sib txawv li cas. … Cov ntaub ntawv zais yog ob qho tib si txheej txheem thiab txheej txheem hauv nws tus kheej, whereas cov ntaub ntawv encapsulation yog sub-process nyob rau hauv cov ntaub ntawv nkaum.
kev paub daws teeb meem pab hauv kev zais cov ntaub ntawv li cas?
Lub hom phiaj tseem ceeb ntawm kev paub daws teeb meem yog zais cov ntsiab lus tsis tsim nyog los ntawm cov neeg siv. Abstraction yog xaiv cov ntaub ntawv los ntawm lub pas dej loj dua kom pom cov ntsiab lus tseem ceeb 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.
Yuav zais cov ntaub ntawv hu li cas?
Data encapsulation, tseem hu ua cov ntaub ntawv zais, yog cov txheej txheem uas qhov kev siv cov ntsiab lus ntawm chav kawm tau muab zais los ntawm tus neeg siv. Tus neeg siv tsuas tuaj yeem ua qhov txwv tsis pub ua haujlwm ntawm cov tswvcuab zais hauv chav kawm los ntawm kev ua haujlwm tshwj xeeb uas feem ntau hu ua txoj hauv kev.
Yuav ua li cas yog cov ntaub ntawv zais?
Data nkaum yog ibsoftware txhim kho cov txheej txheem tshwj xeeb siv rau hauv cov phiaj xwm taw qhia (OOP) txhawm rau zais cov ntsiab lus sab hauv (cov tswv cuab cov ntaub ntawv). Kev zais cov ntaub ntawv kom paub meej cov ntaub ntawv tshwj xeeb rau cov tub kawm thiab tiv thaiv cov khoom ncaj ncees los ntawm kev tiv thaiv kev hloov pauv tsis xav tau lossis xav tau.
