Tab sis hauv Java, txoj hlua yog ib yam khoom uas sawv cev ib ntu ntawm cov cim. The java. lang. hlua chav kawm yog siv los tsim ib txoj hlua khoom.
Raws li, dab tsi yog kev siv cov hlua hauv Java?
Cov hlua , uas yog dav siv hauv Java programming, yog ib ntu ntawm cov cim. Hauv Java programming lus, hlua raug kho raws li yam khoom. Cov Java platform muab cov hlua chav kawm tsim thiab tswj hlua.
Ib tug kuj yuav nug, dab tsi yog txoj hlua thiab nws txoj haujlwm? Txoj hlua ua haujlwm yog siv nyob rau hauv computer programming lus los manipulate a txoj hlua los yog nug cov ntaub ntawv hais txog a txoj hlua (ib txhia ua ob leeg). Qhov yooj yim piv txwv ntawm a txoj hlua ua haujlwm yog qhov ntev ( txoj hlua ) muaj nuj nqi . Qhov no muaj nuj nqi rov qab qhov ntev ntawm a txoj hlua ntawv.
Tsis tas li ntawd, dab tsi yog chav kawm hlua?
Cov hlua chav kawm sawv cev rau tus cwj pwm hlua . Tag nrho txoj hlua literals nyob rau hauv Java cov kev pab cuam, xws li "abc", yog siv raws li piv txwv ntawm qhov no chav kawm . Cov hlua yog tas li; lawv cov txiaj ntsig tsis tuaj yeem hloov pauv tom qab lawv tsim. Txoj hlua buffers txhawb mutable hlua . Vim Txoj hlua Cov khoom tsis hloov pauv lawv tuaj yeem sib koom.
String Java yog dab tsi?
Txoj hlua yog ib ntu ntawm cov cim, piv txwv li. "Nyob zoo" yog ib txoj hlua ntawm 5 cim. Hauv java ua , txoj hlua yog ib yam khoom uas hloov tsis tau uas txhais tau hais tias nws yog tas mus li thiab tsis tuaj yeem hloov tau thaum nws tau tsim.

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 ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
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
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
