Yam khoom Model (OM) • Muaj plaub yam tseem ceeb ntawm OM – Abstraction – Encapsulation – Modularity – Hierarchy • Los ntawm loj , peb txhais tau tias a qauv tsis muaj ib qho ntawm no cov ntsiab lus tsis yog khoom - taw qhia.
Kuj nug, yam khoom raws li Modelling yog dab tsi?
Yam khoom - taw qhia modeling (OOM) yog ib txoj hauv kev los tsim ib daim ntawv thov uas yog siv thaum pib ntawm lub neej software thaum siv lub khoom - taw qhia txoj kev mus rau kev txhim kho software. Kev ua qauv yog ua tiav thaum pib ntawm tus txheej txheem.
Tsis tas li ntawd, dab tsi yog cov ntsiab lus ntawm object oriented programming? Plaub lub hauv paus ntsiab lus ntawm object-oriented programming yog encapsulation , abstraction, qub txeeg qub teg , thiab polymorphism.
Tsis tas li ntawd, cov txiaj ntsig ntawm cov qauv khoom yog dab tsi?
Cov txiaj ntsig ntawm Object Model
- Nws pab hauv kev txhim kho sai ntawm software.
- Nws yog ib qho yooj yim los tswj.
- Nws txhawb kev hloov kho tshiab tsis muaj teeb meem.
- Nws tso cai rau rov siv cov khoom, tsim, thiab ua haujlwm.
- Nws txo cov kev pheej hmoo ntawm kev loj hlob, tshwj xeeb hauv kev koom ua ke ntawm cov txheej txheem nyuaj.
Yam khoom hauv programming yog dab tsi?
Hauv khoom - taw qhia programming (OOP), khoom yog yam koj xav txog thawj zaug hauv kev tsim ib qhov kev pab cuam thiab lawv kuj yog cov units ntawm code uas nws thiaj li muab tau los ntawm tus txheej txheem. Txhua khoom yog ib qho piv txwv ntawm cov chav kawm tshwj xeeb lossis subclass nrog cov chav kawm tus kheej txoj kev lossis cov txheej txheem thiab cov ntaub ntawv sib txawv.

Cov ntsiab lus tseem ceeb yog cov ntsiab lus tseem ceeb uas txhawb nqa lub tswv yim tseem ceeb. Cov kab lus feem ntau muaj cov ntsiab lus me me thiab. Thaum cov ntsiab lus tseem ceeb piav qhia thiab tsim lub tswv yim tseem ceeb, lawv, dhau los tau nthuav dav raws li cov ntsiab lus txhawb nqa me
Dab tsi yog cov ntsiab lus tseem ceeb ntawm OOPs hauv Java?
Kev txhais ntawm OOP Cov Ntsiab Lus hauv Java Lawv yog kev paub daws teeb meem, encapsulation, qub txeeg qub tes, thiab polymorphism. Kev tuav lawv yog qhov tseem ceeb rau kev nkag siab tias Java ua haujlwm li cas. Yeej, Java OOP cov ntsiab lus cia peb tsim txoj hauv kev ua haujlwm thiab hloov pauv, tom qab ntawd rov siv tag nrho lossis ib feem ntawm lawv yam tsis muaj kev cuam tshuam kev nyab xeeb
Dab tsi yog qhov sib txawv ntawm cov qauv siv nyob rau hauv cov ntaub ntawv ntawm cov khoom oriented qauv?
Cov qauv tseem ceeb ntawm cov qauv uas siv rau hauv cov khoom siv yog: Siv cov qauv qauv, Cov qauv qauv (zoo li qub) cov qauv, Cov qauv coj tus cwj pwm (dynamic) khoom qauv
Vim li cas cov ntsiab lus hauv kev sib txuas lus tseem ceeb?
Cov ntsiab lus tseem ceeb vim nws pab koj txuas thiab tsim kev sib raug zoo nrog tus nyeem ntawv. Nws pab koj sib txuas lus koj qhov kev xav kom meej kom nkag siab yooj yim dua. Nws tso cai rau koj thiab lwm tus muaj tswv yim ntau dua
Dab tsi yog tus hais lus sau nws lub hom phiaj thiab dab tsi yog yam tseem ceeb uas yuav tsum nco ntsoov txog cov lus hais?
Cov neeg hais lus sau ntawv yog cov ntawv qhia uas tus neeg nthuav qhia siv thaum nthuav qhia qhov kev nthuav qhia. Lawv pab tus neeg nthuav qhia nco txog cov ntsiab lus tseem ceeb thaum muab kev nthuav qhia. Lawv tshwm sim ntawm tus swb thiab tuaj yeem pom tsuas yog los ntawm tus tshaj tawm thiab tsis yog cov neeg tuaj saib
