Ib interface yog hom siv hauv Java . Nws zoo ib yam li chav kawm . Nws yog ib phau ntawm abstract method. A chav kawm siv ib interface , yog li inheriting lub abstract txoj kev ntawm lub interface . Nrog rau cov txheej txheem abstract, ib interface kuj tseem tuaj yeem muaj qhov tsis tu ncua, cov txheej txheem ua ntej, cov txheej txheem zoo li qub, thiab hom nested.
Dhau li ntawm no, dab tsi yog chav kawm thiab interface?
A chav kawm piav txog tus cwj pwm thiab tus cwj pwm ntawm ib yam khoom. Ib interface muaj cov cwj pwm uas a chav kawm siv. A chav kawm tej zaum yuav muaj cov kev paub daws teeb meem, kev ua vaj tse. Ib interface tsuas muaj txoj kev paub daws teeb meem xwb. Cov tswv cuab ntawm a chav kawm tuaj yeem yog pej xeem, ntiag tug, tiv thaiv lossis ua tsis tau.
Tsis tas li ntawd, vim li cas peb thiaj siv interface hauv Java?
- Nws yog siv los ua kom tiav tag nrho abstraction.
- Txij li thaum java tsis txhawb ntau qhov qub txeeg qub teg hauv chav kawm, tab sis los ntawm kev siv interface nws tuaj yeem ua tiav ntau yam qub txeeg qub teg.
- Nws kuj yog siv los ua kom xoob coupling.
- Interfaces yog siv los ua kom tiav abstraction.
Xav txog qhov no, qhov txawv ntawm qhov interface thiab chav kawm hauv Java yog dab tsi?
Ib interface muaj tag nrho cov kev paub daws teeb, piv txwv li txoj kev uas tsis muaj leej twg. Ib interface yog syntactically zoo ib yam li cov chav kawm tab sis muaj ib qho loj qhov txawv ntawm chav kawm thiab interface uas yog a chav kawm yuav instantiated, tab sis ib interface yeej tsis tau instantiated. Cov tswv cuab ntawm a chav kawm tuaj yeem ua tus kheej, pej xeem lossis tiv thaiv.
Dab tsi yog qhov interface?
Hauv kev suav, ib interface yog ib thaj tsam sib koom ntawm ob lossis ntau qhov sib cais ntawm lub khoos phis tawj sib pauv cov ntaub ntawv. Kev sib pauv tuaj yeem yog nruab nrab ntawm software, khoos phis tawj kho vajtse, cov khoom siv txuas ntxiv, tib neeg, thiab kev sib txuas ntawm cov no.

Dab tsi yog qhov txawv ntawm chav kawm sab hauv thiab cov chav nested?
Cov chav kawm uas tau tshaj tawm yam tsis siv qhov zoo li qub yog hu ua chav kawm sab hauv lossis chav kawm tsis zoo li qub. Cov chav kawm Staticnested yog chav kawm zoo li lwm cov tswv cuab zoo li qub ntawm cov chav kawm sab nrauv. Txawm li cas los xij, cov chav kawm sab hauv yog khi toinstance thiab nws tuaj yeem nkag mus rau cov tswv cuab ntawm pawg enclosingclass
Dab tsi yog ob chav kawm tshwj xeeb hauv hierarchy ntawm Java zam chav kawm?
Chav Kawm Exception muaj ob lub ntsiab subclasses: IOException class thiab RuntimeException Class. Hauv qab no yog cov npe ntawm feem ntau kuaj xyuas thiab tsis tau txheeb xyuas Java's Built-in Exceptions
Peb puas tuaj yeem muaj ntau chav kawm pej xeem hauv chav kawm hauv Java?
Yog, nws ua tau. Txawm li cas los xij, muaj peev xwm tsuas yog ib pawg pej xeem ib. java cov ntaub ntawv, raws li publicclasses yuav tsum muaj tib lub npe raws li cov ntaub ntawv qhov chaw. OneJava cov ntaub ntawv tuaj yeem muaj ntau chav kawm nrog kev txwv uas tsuas yog ib qho ntawm lawv tuaj yeem ua pej xeem
Chav kawm piav qhia txog tus qauv ntawm chav kawm yog dab tsi?
Nyob rau hauv object-oriented programming, ib chav kawm yog ib tug template txhais ntawm txoj kev s thiab txawv txawv s nyob rau hauv ib tug tej yam khoom. Yog li, ib yam khoom yog ib qho piv txwv tshwj xeeb ntawm chav kawm; nws muaj cov txiaj ntsig tiag tiag tsis yog hloov pauv. Cov qauv ntawm ib chav kawm thiab nws cov subclasses yog hu ua chav kawm hierarchy
Dab tsi yog kev siv cov ntawv cim kev cai li cas koj nkag mus rau hauv Apex cov chav kawm thiab hauv Visualforce nplooj ntawv?
Cov ntawv sau kev cai tso cai rau cov neeg tsim khoom tsim cov ntawv thov ntau hom lus los ntawm kev nthuav qhia cov ntaub ntawv (piv txwv li, pab cov ntawv lossis cov lus yuam kev) hauv tus neeg siv hom lus. Cov ntawv sau kev cai yog cov ntawv sau muaj txiaj ntsig uas tuaj yeem nkag tau los ntawm Apex cov chav kawm, nplooj ntawv Visualforce, lossis cov khoom siv xob laim
