Jacl: The Tcl Java kev siv. Jython: Python Java kev siv. Rhino: The JavaScript Java kev siv. BeanShell: A Java tus neeg txhais lus sau rau hauv Java.
Tsis tas li ntawd, Java tuaj yeem siv rau kev sau ntawv?
Lo lus teb yog 'Yog', koj ua tau siv Java as a sau ntawv lus hauv ib Java program nws tus kheej. Tsis tas li ntawd, muaj ob peb lwm yam lus uas ua tau kuj be siv rau lub hom phiaj no - Javascript, LUA, Groovy, Ruby, cov npe ntev. Kev koom ua ke tau ua kom yooj yim dua nrog kev qhia txog javax.
vim li cas Java yog ib hom lus sau ntawv? Txawm tias scripting lus feem ntau txhais tau ntawm runtime, lawv tuaj yeem muab tso ua ke rau hauv Java bytecode uas tuaj yeem ua tiav ntawm qhov Java Virtual Machine (JVM). Scripting lus tuaj yeem siv sai dua thiab yooj yim dua rau qee yam teeb meem, yog li qee zaum nws raug xaiv los ntawm cov neeg tsim khoom ntawm Java daim ntawv thov.
Xav txog qhov no, kev siv cov lus sau ntawv yog dab tsi?
Scripting lus , uas tuaj yeem muab tso rau hauv HTML, feem ntau yog siv los ntxiv kev ua haujlwm rau nplooj ntawv Web, xws li cov ntawv qhia zaub mov sib txawv lossis cov duab kos duab lossis ua haujlwm rau kev tshaj tawm dynamic. Cov hom no yam lus yog cov neeg siv khoom sab scripting lus , cuam tshuam cov ntaub ntawv uas tus neeg siv kawg pom hauv lub qhov rais browser.
Koj sau ib hom lus li cas?
Tsim cov lus sau ua lwm txoj hauv kev rau JavaScript xav kom koj:
- Tsim koj tus kheej syntax.
- Txhais qhov no syntax nyob rau hauv ib tug specification.
- Sau tus neeg txhais lus uas nkag siab txog cov lus qhia tshiab no. Tus neeg txhais lus no tuaj yeem sau ua lus programming, txawm tias koj yuav xav siv C lossis C ++.

Lub hom phiaj ntawm hom lus hom lus yog dab tsi?
Hom Lus Specification. Ib Hom Lus Qhia Tshwj Xeeb (CLS) yog ib daim ntawv uas hais tias yuav ua li cas cov khoos phis tawj tuaj yeem hloov mus rau hauv Cov Lus Qhia Nruab Nrab (CIL) code. Thaum ntau hom lus siv tib bytecode, qhov sib txawv ntawm qhov kev pab cuam tuaj yeem sau ua hom lus sib txawv
Dab tsi yog lub hom phiaj ntawm delimiters nyob rau hauv cov ntawv sau npe ob hom ntawv cov ntaub ntawv delimiters?
Cov ntaub ntawv delimited yog cov ntawv nyeem siv los khaws cov ntaub ntawv, uas txhua kab sawv cev rau ib phau ntawv, tuam txhab, lossis lwm yam, thiab txhua kab muaj cov teb sib cais los ntawm tus lej
Dab tsi ntawm cov hauv qab no yog hais txog cov txheej txheem ntawm tus kheej muaj cov kev pabcuam uas sib txuas lus los tsim ib daim ntawv thov software ua haujlwm?
Ib qho kev pabcuam-oriented architecture yog teeb tsa cov kev pabcuam tus kheej uas sib txuas lus nrog ib leeg los tsim ib daim ntawv thov software ua haujlwm. Nyob rau hauv ib tug ntau-tiered network: kev ua hauj lwm ntawm tag nrho cov network yog sib npaug ntawm ntau theem ntawm servers
Dab tsi yog cov khoom tsim nyog los tsim cov ntawv thov Web?
Cov khoom siv hauv web-based applications. Txhua qhov web-based database applications muaj peb yam tseem ceeb: Ib lub web browser (lossis tus neeg siv), lub web application server, thiab database server
Dab tsi yog tus hais lus sau nws lub hom phiaj thiab dab tsi yog yam tseem ceeb uas yuav tsum nco ntsoov txog cov lus hais?
Cov neeg hais lus sau ntawv yog cov ntawv qhia uas tus neeg nthuav qhia siv thaum nthuav qhia qhov kev nthuav qhia. Lawv pab tus neeg nthuav qhia nco txog cov ntsiab lus tseem ceeb thaum muab kev nthuav qhia. Lawv tshwm sim ntawm tus swb thiab tuaj yeem pom tsuas yog los ntawm tus tshaj tawm thiab tsis yog cov neeg tuaj saib
