Cov yam ntxwv ntawm OOP yog:
Abstraction - Qhia meej tias yuav ua li cas tab sis tsis ua li cas; ib tug saj zawg zog feature kom muaj ib tug zuag qhia tag nrho saib ntawm ib tug cov khoom kev ua haujlwm. Encapsulation - Kev khi cov ntaub ntawv thiab kev ua haujlwm ntawm cov ntaub ntawv ua ke hauv ib chav tsev - Ib chav kawm ua raws li qhov tshwj xeeb no.
Ib yam li ntawd, nws yog nug, dab tsi yog yam ntxwv ntawm cov khoom taw qhia kev ua haujlwm?
Cov yam ntxwv tseem ceeb ntawm Object Oriented programming yog: Inheritance. Polymorphism. Cov ntaub ntawv zais. Encapsulation.
Tsis tas li ntawd, cov yam ntxwv ntawm ib yam khoom yog dab tsi? Cov yam ntxwv ntawm cov khoom
- Ib yam khoom muaj tus kheej (txhua yam khoom yog tus kheej).
- Ib yam khoom muaj lub xeev (nws muaj ntau yam khoom, uas tej zaum yuav hloov).
- Ib yam khoom muaj tus cwj pwm (nws tuaj yeem ua tej yam thiab muaj peev xwm ua tau rau nws).
Ib sab ntawm qhov no, lub ntsiab lus ntawm cov phiaj xwm taw qhia yog dab tsi?
Yam khoom - oriented programming ( OOP ) hais txog ib hom computer programming (software design) uas programmers txhais cov ntaub ntawv hom ntawm datastructure, thiab kuj yog hom kev ua haujlwm (functions) uas tuaj yeem siv tau rau cov qauv ntaub ntawv.
Dab tsi yog Object Oriented Programming hauv cov lus yooj yim?
Yam khoom - oriented programming ( OOP ) yog ib txoj hauv kev sau cov khoos phis tawj siv lub tswv yim ntawm " khoom " sawv cev cov ntaub ntawv thiab cov txheej txheem. Tsis tas li ntawd, vim txoj kev khoom - oriented programming yog tsim los, nws pab tus tsim tawm los ntawm kev tso cai rau cov cai kom yooj yim rov siv dua los ntawm lwm qhov chaw ntawm lub qhov kev pab cuam los yog los ntawm lwm tus neeg.
