Qhov Tseem Ceeb Qhov Sib Txawv - Ntau Vs Ntau Qhov Kev Cuam Tshuam
Object-Oriented Programming (OOP) yog ib qho piv txwv los tsim ib qho kev pab cuam uas siv cov chav kawm thiab txoj hauv kev. Cov xwm txheej hauv ntiaj teb tiag tuaj yeem ua rau cov khoom. Yog li ntawd, nws yog ib qho yooj yim los tsim software daws teeb meem. Ib chav kawm yog ib daim phiaj los tsim ib yam khoom. Nws muaj cov khoom thiab cov txheej txheem. Piv txwv li, ua ntej tsim cov tub ntxhais kawm cov khoom, yuav tsum muaj cov tub ntxhais kawm hauv chav kawm nrog cov khoom thiab cov txheej txheem. Tus menyuam kawm ntawv tuaj yeem muaj cov khoom xws li tus menyuam kawm ntawv ID, lub npe thiab txoj hauv kev xws li nyeem, sau ntawv, kawm. Cov txheej txheem piav qhia tus cwj pwm thaum cov khoom yog cov cwj pwm. Tom qab tsim cov chav kawm, nws muaj peev xwm tsim cov khoom siv lawv. Object creation kuj hu ua Object Instantiation. Yam khoom tsis muaj nyob hauv kev sib cais. Lawv sib txuas lus nrog lwm yam khoom thiab cov ntaub ntawv yog kis nyob rau hauv cov khoom. Ib tug ncej ntawm OOP yog Inheritance. Lub hom phiaj ntawm Inheritance yog txhawm rau txhim kho cov cai rov siv tau. Nws tsim ib chav kawm tshiab ntawm cov khoom thiab cov txheej txheem ntawm cov chav kawm uas twb muaj lawm. Cov chav kawm uas twb muaj lawm yog lub npe hu ua cov chav kawm hauv paus, thiab chav kawm tshiab hu ua chav derived. Multiple Inheritance thiab Multilevel Inheritance yog hom qub txeeg qub teg. Kab lus no tham txog qhov sib txawv ntawm lawv. Qhov sib txawv tseem ceeb ntawm Multiple thiab Multilevel Inheritance yog qhov Multiple Inheritance yog thaum ib chav kawm tau txais txiaj ntsig los ntawm ntau cov chav hauv paus thaum Multilevel Inheritance yog thaum cov chav kawm tau txais txiaj ntsig los ntawm cov chav kawm uas tau muab los ua cov chav kawm hauv paus rau chav kawm tshiab.
Yuav ua li cas ntau yam?
Multiple Inheritance yog thaum ib chav kawm tau txais ntau dua ib chav kawm.
Daim duab 01: Ntau Yam Khoom
A B thiab C yog chav kawm. A thiab B yog cov chav kawm hauv paus, thiab C yog chav kawm muab los. Chav kawm C yuav tsum tswj hwm qhov kev cia siab ntawm ob chav kawm A thiab B. Ntau yam qub txeeg qub teg tsis yog siv dav hauv cov haujlwm software. Nws ua rau lub kaw lus nyuaj dua vim tias ib chav kawm tau txais ntau chav kawm.
Piv txwv li, xav tias chav kawm A thiab B ob leeg muaj ib txoj hauv kev nrog tib lub npe uas yog tus lej () thiab chav kawm C yog muab los ntawm ob chav kawm. Tom qab tsim ib qho khoom ntawm hom C thiab hu rau sum () txoj kev, nws tuaj yeem ua rau muaj qhov yuam kev vim tias ob chav kawm muaj tib txoj kev. Lub compiler tsis paub yuav hu ua haujlwm twg. Yog li ntawd, Multiple Inheritance nce lub complexity ntawm ib tug system. Ntau Qhov Kev Tsim Txiaj Ntsig tau txais kev txhawb nqa hauv C ++ hom lus tab sis cov lus xws li Java, C tsis txhawb nqa Ntau Qhov Kev Cai. Hloov chaw, cov lus no siv interface uas zoo ib yam li chav kawm tab sis tsis tuaj yeem ua sai sai.
Yuav ua li cas Multilevel Inheritance?
Multilevel Inheritance yog thaum ib chav kawm tau txais txiaj ntsig los ntawm cov chav kawm muab tau los ua cov chav kawm uas tau muab los ntawm cov chav kawm hauv paus rau chav kawm tshiab.
Daim duab 02: Ntau theem kev cuab yeej cuab tam
Multilevel qub txeeg qub teg muaj peb theem. Cov chav kawm nruab nrab uas B tau txais los ntawm chav kawm A thiab chav kawm C tau txais los ntawm chav kawm B. A yog chav kawm hauv B thiab B yog chav kawm hauv C.
Ib txoj haujlwm uas siv Multilevel Inheritance yog raws li hauv qab no. Qhov program no sau siv Java.
Daim duab 03: Txoj Haujlwm uas siv ntau theem Kev Nkag Tebchaws
Raws li cov kev kawm saum toj no, chav kawm A yog chav kawm hauv chav kawm B. Chav B yog chav kawm hauv chav C. Txhua yam khoom thiab cov txheej txheem ntawm chav kawm A yog nkag tau los ntawm chav kawm B. Txhua yam khoom thiab cov txheej txheem ntawm chav kawm B yog nkag tau los ntawm chav kawm C. Yog li ntawd, chav kawm C tuaj yeem nkag mus rau cov khoom thiab cov txheej txheem ntawm ob qho tib si A thiab B. Thaum tsim cov khoom ntawm hom C, nws tuaj yeem hu rau tag nrho peb hom A (), B () thiab C (). Cov zis yuav muab A, B, C.
Dab tsi yog qhov zoo sib xws ntawm Ntau thiab Ntau Qhov Kev Txawj Ntse?
Ob leeg yog hom Inheritance
Dab tsi yog qhov txawv ntawm Ntau thiab Ntau Qhov Kev Sib Txuas?
Multiple Inheritance vs Multilevel Inheritance |
|
| Multiple Inheritance is an Inheritance type where a class inherits from ntau tshaj ib hoob hauv paus. | Multilevel Inheritance yog ib yam khoom qub txeeg qub teg uas tau txais los ntawm cov chav kawm derived, ua rau cov chav kawm uas tau muab los ua ib chav hauv paus rau chav kawm tshiab. |
| Ntau Qhov Kev Tsim Txiaj Ntsig tsis yog siv dav vim nws ua rau lub kaw lus nyuaj. | Multilevel Inheritance yog siv dav. |
| Ntau yam cuab yeej cuab tam muaj ob chav kawm xws li, chav kawm hauv paus thiab derived class. | Multilevel Inheritance muaj peb chav kawm xws li, chav kawm hauv paus, chav kawm nruab nrab thiab qib muab tau los. |
Summary – Ntau vs Multilevel Inheritance
Txoj kev cuab yeej cuab tam yog tus ncej tseem ceeb ntawm Object Oriented Programming. Muaj ntau hom Inheritance; lawv yog Tib Theem Inheritance, Multilevel Inheritance, Multiple Inheritance, Hierarchical Inheritance thiab Hybrid Inheritance. Ib Theem Ib Leeg Inheritance muaj ib chav hauv paus thiab ib chav muab tau los. Hierarchical Inheritance muaj ib chav kawm hauv paus thiab ntau chav muab tau los. Hybrid Inheritance yog kev sib xyaw ua ke ntawm Multilevel thiab Multiple Inheritance. Kab lus no tau piav qhia txog qhov sib txawv ntawm Ntau Qhov Kev Tsim Txiaj Ntsig thiab Multilevel Inheritance. Qhov sib txawv ntawm Multiple thiab Multilevel qub txeeg qub teg yog qhov Multiple Inheritance yog thaum ib chav kawm tau txais los ntawm ntau lub hauv paus chav kawm thaum Multilevel Inheritance yog thaum ib chav kawm tau txais los ntawm cov chav kawm muab los, ua rau cov chav kawm tau txais los ntawm cov chav kawm tshiab. Multilevel Inheritance yog siv dav dua li Ntau Qhov Kev Tsim Txiaj Ntsig.
