Java yog cas - rhiab heev vim nws siv C-style syntax. Case rhiab heev muaj txiaj ntsig vim nws tso cai rau koj nkag siab tias lub npe txhais li cas raws li nws cas . Piv txwv li, lub Java tus qauv rau cov npe hauv chav kawm yog qhov loj tshaj thawj tsab ntawv ntawm txhua lo lus (Integer, PrintStream, thiab lwm yam).
Hauv qhov no, dab tsi yog cov ntaub ntawv nkag siab hauv programming?
A cas - rhiab program uas xav kom koj nkag mus rau tag nrho cov lus txib nyob rau hauv cov ntawv loj yuav tsis teb kom raug yog tias koj nkag mus rau ib lossis ntau tus cim hauv tus lej me. Nws yuav kho cov lus txib RUN txawv ntawm kev khiav. Cov kev pab cuam uas tsis paub qhov txawv nruab nrab ntawm cov tsiaj ntawv loj thiab cov ntawv me tau hais tias yog cas - insensitive.
Cov lus programming twg yog qhov tseem ceeb? Hauv programming lus Ib txhia programming lus yog case - rhiab heev rau lawv cov cim (C, C ++, Java, C#, Verilog, Ruby thiab Python). Lwm tus yog cas - insensitive (ie, tsis cas - rhiab heev ), xws li ABAP, Ada, feem ntau BASICs (anexception yog BBC BASIC), Fortran, SQL thiab Pascal.
Tsuas yog li ntawd, Java case rhiab lossis tsis?
Yog, nws yog cas - rhiab heev . Nws yog txoj kev no vim nws cov cuab yeej cuab tam los ntawm C. Kom cov lus paub ntau dua li cov neeg tau siv rau "hnub", lawv tau tso nws li. cas - rhiab heev . Muaj ib qho txiaj ntsig ntxiv txij li Java Cov cim qhia tuaj yeem yog yuav luag txhua tus cim Unicode.
Puas yog cov npe sib txawv ntawm qhov teeb meem?
Case Sensitivity . JavaScript yog a cas - rhiab heev lus. Qhov no txhais tau hais tias cov lus tseem ceeb, sib txawv , ua haujlwm npe , thiab lwm tus neeg txheeb xyuas yuav tsum tau ntaus nrog ib tus lej loj ntawm cov ntawv. Nco ntsoov, txawm li cas los xij, qhov HTML tsis yog cas - rhiab heev.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Vim li cas nws yog ib qho tseem ceeb los cais kev lag luam thiab nws cov khoom siv rau hauv qib?
Nov yog 5 qhov txiaj ntsig ntawm kev sib cais daim ntawv thov rau hauv qib: Nws muab koj lub peev xwm los hloov kho cov txheej txheem thev naus laus zis ntawm ib qib, tsis muaj kev cuam tshuam rau lwm thaj chaw ntawm daim ntawv thov. Nws tso cai rau pab pawg txhim kho sib txawv rau txhua qhov haujlwm ntawm lawv tus kheej cov kev txawj ntse
Vim li cas nws tseem ceeb kom khaws cov ntaub ntawv tsis pub lwm tus paub hauv kev noj qab haus huv thiab kev saib xyuas kev noj qab haus huv?
Ib qho tseem ceeb tshaj plaws ntawm kev ceev ntiag tug yog tias nws pab tsim thiab txhim kho kev ntseeg siab. Nws muaj peev xwm tso cai rau cov ntaub ntawv pub dawb ntawm cov neeg siv khoom thiab cov neeg ua haujlwm thiab lees paub tias tus neeg siv khoom lub neej thiab txhua yam teeb meem thiab teeb meem uas lawv muaj rau lawv
Vim li cas cov ntaub ntawv zoo tseem ceeb heev rau kev sau cov ntaub ntawv txheeb cais?
Cov ntaub ntawv muaj txiaj ntsig zoo yuav ua kom muaj txiaj ntsig ntau dua hauv kev tsav lub tuam txhab kev vam meej vim yog kev vam khom ntawm qhov tseeb-raws li kev txiav txim siab, tsis yog kev coj cwj pwm lossis tib neeg kev xav. Ua kom tiav: Xyuas kom tsis muaj qhov khoob ntawm cov ntaub ntawv los ntawm qhov yuav tsum tau sau thiab qhov twg tau sau tiag
Vim li cas nws tseem ceeb heev uas yuav tsum tau nyob nrog cov cuab yeej technology?
Kev vam meej ntawm kev siv tshuab tau hloov txoj kev lag luam. Technology pab koj muab koj cov neeg siv khoom zoo dua rau koj cov neeg siv khoom thiab ua rau koj ua ntej ntawm cov neeg sib tw. Yog li ntawd nws yog ib qho tseem ceeb kom nyob twj ywm rau hnub tim ntawm tech tiam sis yog li koj txoj kev lag luam tsis poob qab los yog tsis muaj lub cib fim
