Cov tus qauv zoo yog siv rau daws teeb meem uas tej zaum (los yog pom tias lawv yuav) yuav raug siv los yog daws los ntawm txawv cov tswv yim thiab uas muaj ib qho kev qhia meej meej rau cov xwm txheej zoo li no.
Ib yam li ntawd, koj tuaj yeem nug, kev siv lub tswv yim tsim qauv yog dab tsi?
Hauv computer programming, lub tus qauv zoo (tseem hu ua txoj cai qauv ) yog kev coj cwj pwm software tsim qauv uas enables xaiv ib qho algorithm ntawm runtime. Hloov chaw ntawm kev siv ib qho algorithm ncaj qha, cov lej tau txais cov lus qhia ua haujlwm raws li qhov twg hauv tsev neeg ntawm algorithms rau siv.
Qhov thib ob, dab tsi yog cov ntsiab lus hauv lub tswv yim qauv? Cov Lub tswv yim qauv qhia tias koj kawm ib chav kawm uas ua tej yam tshwj xeeb hauv ntau txoj kev sib txawv thiab rho tawm tag nrho cov algorithms no rau hauv cov chav kawm cais hu ua cov tswv yim . Thawj chav kawm, hu ua ntsiab lus , yuav tsum muaj ib daim teb rau khaws cov ntaub ntawv siv rau ib qho ntawm cov tswv yim.
Kuj nug, qhov txawv ntawm lub Hoobkas thiab cov qauv zoo li cas?
A Hoobkas qauv yog creational qauv . A tus qauv zoo yog kev ua haujlwm qauv . Muab lwm txoj kev, a Hoobkas qauv yog siv los tsim cov khoom ntawm ib hom tshwj xeeb. A tus qauv zoo yog siv los ua ib qho kev ua haujlwm (los yog txheej txheem ua haujlwm) hauv a yam tshwj xeeb.
Cov qauv zoo li cas siv hauv Java?
Design Patterns - Strategy Patterns
- Tsim ib qho interface. Strategy.java public interface Strategy { pej xeem int doOperation(int num1, int num2); }
- Tsim cov chav kawm ua vaj tse siv tib lub interface.
- Tsim cov ntsiab lus hauv chav kawm.
- Siv Cov Ntsiab Lus kom pom kev hloov pauv ntawm tus cwj pwm thaum nws hloov nws Txoj Cai.
- 10 + 5 = 15 10 - 5 = 5 10 * 5 = 50.

Muaj pes tsawg txoj kev daws teeb meem tuaj yeem muaj teeb meem LP?
"Tsis yog, nws tsis tuaj yeem ua rau tus qauv LP kom muaj ob qho kev daws teeb meem zoo." Tus qauv LP tuaj yeem muaj 1 qhov kev daws teeb meem zoo tshaj plaws lossis ntau dua 1 qhov kev daws teeb meem zoo, tab sis nws tsis tuaj yeem muaj 2 qhov kev daws teeb meem zoo
Dab tsi yog chav kawm paub daws teeb meem hauv C# Cov Lus Nug Sib Tham?
C# thiab. NET kev xam phaj cov lus nug: -Dab tsi yog qhov txawv ntawm chav kawm paub daws teeb meem thiab kev sib tshuam? Abstract class Interface Variable declaration Peb tuaj yeem tshaj tawm qhov sib txawv hauv interface peb ua tsis tau. Inheritance vs Implementation Abstract classes are inherited. Interfaces yog siv
Kuv yuav daws teeb meem OneDrive sync teeb meem li cas?
Txhim kho OneDrive sync teeb meem Xyuas kom OneDrive khiav. Manually launchOneDrive los ntawm kev mus rau Start, ntaus onedrive hauv cov thawv ntawv no, tom qab ntawd xaiv OneDrive (Desktop app) los ntawm cov npe ntawm cov txiaj ntsig. Nco ntsoov tias koj cov ntaub ntawv qis dua OneDrive cov ntaub ntawv loj txwv ntawm 15 GB. Nco ntsoov tias koj muaj qhov hloov tshiab Windows tshiab thiab qhov tseeb version ntawm OneDrive
Dab tsi yog peb qhov tseem ceeb ntawm cov ntaub ntawv los daws cov teeb meem tshawb fawb txog kev lag luam?
Peb qhov chaw ntawm kev paub txog kev lag luam yog cov ntaub ntawv sab hauv, cov ntaub ntawv tseem ceeb, thiab cov ntaub ntawv thib ob. Cov ntaub ntawv sab hauv yog qhov zoo tshaj plaws rau kev saib xyuas kev muag khoom, sib qhia, thiab cov hom phiaj ntawm kev lag luam
Dab tsi yog qhov xav tau rau cov chav kawm paub daws teeb meem thiab kev paub daws teeb meem?
Cov chav kawm Abstract. Abstract (uas Java txhawb nrog cov ntsiab lus paub daws teeb meem) txhais tau hais tias chav kawm lossis txoj hauv kev lossis teb lossis txhua yam tsis tuaj yeem ua tam sim (uas yog, tsim) qhov twg nws tau txhais. Lwm yam khoom yuav tsum instantiate cov khoom nyob rau hauv nqe lus nug. Yog tias koj ua ib chav kawm abstract, koj tsis tuaj yeem instantiate ib yam khoom los ntawm nws
