Java - Cov Teeb Interface. Kev tshaj tawm. A Teeb yog ib qho Collection uas tsis tuaj yeem muaj cov khoom sib npaug. Nws ua qauv lej teeb abstraction. Cov Teeb interface muaj tsuas yog txoj kev tau txais txiaj ntsig los ntawm Kev Sau thiab ntxiv cov kev txwv uas txwv tsis pub sib tshooj.
Sib piv, dab tsi yog teeb tsa thiab tau txais hauv Java?
To taub tau thiab teeb , nws yog txhua yam hais txog yuav ua li cas hloov pauv ntawm cov chav kawm sib txawv. Cov tau txoj kev yog siv kom tau los yog retrieve ib tug tshwj xeeb variable nqi ntawm ib chav kawm. A teeb tus nqi yog siv los khaws cov variables. Tag nrho cov ntsiab lus ntawm lub tau thiab teeb yog mus retrieve thiab khaws cov ntaub ntawv muaj nuj nqis raws li.
Ib yam li ntawd, puas muaj teeb meem hauv Java? Cov Java platform muaj peb lub hom phiaj dav dav Teeb Kev siv: HashSet, TreeSet, thiab LinkedHashSet. HashSet, uas khaws nws cov ntsiab lus hauv lub rooj hash, yog qhov ua tau zoo tshaj plaws; txawm li cas los xij nws tsis muaj kev lees paub txog qhov kev txiav txim ntawm iteration.
Tsuas yog li ntawd, lub teeb ua haujlwm li cas hauv Java?
Kev siv HashSet nyob rau hauv Java . Teeb ua tiav qhov tshwj xeeb hauv nws cov ntsiab lus los ntawm HashMap. Thaum ib qho khoom raug xa mus rau Teeb , nws yog ntxiv raws li tus yuam sij hauv HashMap hauv qhov ntxiv (Element e) txoj kev. Tam sim no, tus nqi yuav tsum tau txuam nrog tus yuam sij.
Puas yog ib qho teeb meem Java?
Cov Teeb interface siv lub Java Iterable interface. Tias yog vim li cas koj tuaj yeem iterate cov ntsiab lus ntawm a Teeb siv rau-txhua lub voj voog.

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 qhov tseem ceeb ntawm IT Essentials chav kawm muaj nyob hauv Cisco Academy cov ntaub ntawv kawm?
Dab tsi yog qhov tseem ceeb ntawm IT Essentials chav kawm muaj nyob hauv Cisco Academy cov ntaub ntawv kawm? Nws qhia cov neeg kawm paub txog cov hauv paus ntawm lub computer hardware thiab software. Lub zej zog IT twg yog kev sau cov peev txheej tsim los rau cov tib neeg uas xav tsim kev txawj ntse thiab ua raws li Cisco ntawv pov thawj?
