IDE Java

Nge nomqondo yesikhulumi Java ajwayelekile cishe njalo umnikazi we iselula bakudala. Java ukuthuthukiswa imvelo ihlanganisa ukwenziwa isicelo jikelele engasetshenziswa ukusebenzisa, kungakhathaliseki ukuthi uhlelo lokusebenza. Ake sicabangele izici eziyisisekelo ukusebenza kwawo kanye nokusetshenziswa.

Siyini-Java ukuthuthukiswa imvelo?

Eqinisweni, imvelo nokuthuthukiswa kuphela ulimi lokwakha izinhlelo esekelwe imiyalo jikelele ukuthi baziwa e Java Isikhathi Imvelo.

ukukhuluma Cishe, Java ukuthuthukiswa kolimi imvelo ngaphandle platform aqale amiswa Windows efanayo ngeke zisebenze. Kodwa ukusekelwa okunjalo inikezwa natively, ekuqedeni yimuphi umsebenzisi kusukela isidingo ukufaka izingxenye ezengeziwe.

Izinhlelo zokusebenza ubuchwepheshe bama-computer

Ekuqaleni, le phrojekthi yasungulwa ngu-Sun Microsystems, okwathi ngokuhamba kwesikhathi asekelwe inkampani Oracle.

Okuqukethwe ikhodi elisebenzisekayo yokuthi awusebenzi kuxhomeke ohlotsheni yesistimu yokusebenza ezifakiwe. Ulimi ngokwalo lisho amathuluzi ukuthuthukiswa into-ngamakhasimende, nhlelo lifana izinhlelo.

Kodwa ekugcineni Java ukuthuthukiswa imvelo kusuka kwikhompyutha noma izinhlelo mobile kuba ngokuphelele ezimele.

amamojuli esakhelwe ngaphakathi amasistimu mobile

Uma sikhuluma Smartphones kanye amaphilisi, inguqulo efanayo Eclipse (IDE Java) usebenza kuphela ukusetshenziswa isicelo sokuqhafaza evumela ukudala isicelo kwi-Java namalogo emva kwamaminithi ambalwa.

Empeleni, isicelo ngokwalo bakhiqiza ezinye nophenyo ekhuluma noma, ogama imisebenzi zinikezwa yesistimu yokusebenza.

Futhi lokhu kusebenza kumadivayisi eselula. Siqaphele ukuthi ngezinye izikhathi ekugcineni noma i-Windows Ucingo, noma i-Android iqala "amathe" ngokuya izipesheli izibuyekezo ngokushesha? Akukhona ukuthi ezinye, njengoba izingxenye ezimbili:

• Java Isikhathi;
• Microsoft .NET Framework.

Kuyini sad kakhulu, ingxenye yokuqala awahlobene uhlelo amaphutha. Isiteji izimele ngokuphelele futhi wabulawa ngokoMthetho imiyalo okuzenzakalelayo.

Oluhlanganyele lokuthuthukiswa komasipala ukuthuthukiswa imvelo Java: Isicelo Simple

Iqiniso ukuthi lesi simiso isetshenziswa izinguqulo mobile, akekho nokungokoqobo akunakungatshazwa. Isekela ukuthuthukiswa Java imvelo Android, ingasaphathwa eyabantu "apula" imikhiqizo.

Nokho ngokuya isimo akusona izicelo ngakho elula elisebenzisekayo. Nasi isizathu.

applets elisebenzisekayo

Okokuqala, nje unake ohlelweni lapho archiver ezifanele (WinRAR - okungenani kangcono - 7--zip) kufanele sifakwe.

Ukuthuthukiswa imvelo-Java uhlelo libhekisela yokuthi idatha lilondolozwe ingobo yomlando ukuthi ayitholakali ukuvula standard Windows amathuluzi.

idatha egciniwe

Okuhle kakhulu, le extractors angasetshenziswa like okungenhla. Kodwa uma kumiswa ingobo yomlando ubuchwepheshe esetshenziswa ezengeziwe (esiphezulu) kokucindezelwa indlela lapha ngeke kusize lutho.

Ngisho ubuyekeze archiver ngeke bakwazi ukwenza izinguquko ezidingekayo. Kube kuyodingeka ufake isibuyekezo yesikhulumi lonke, nakuba umyalezo kokuqala mayelana siyatholakala "silengela" kuthreyi yesistimu.

platform buyekeza

I-update wenziwa nje. Vele uchofoze isithonjana ugqoko is agqoke, ukunikela ukufaka isibuyekezo esitholakalayo. ukuqashelwa kwesikhathi kungathatha kufika imizuzu eminingana. Lokhu kuvamile.

Uma ungafuni ukulinda, akunankinga - uya share esemthethweni Microsoft bese ulanda uhlelo kusuka lapho. Angiyithandi le ndlela? Fakela JDK noma J2SE, okuyinto ezinwetshiwe Java, futhi kamuva Ukuze ufake amamojuli kunesidingo kusuka akhethiwe, bese kusebenze kwenzeka ngokuzenzakalelayo. Ekupheleni inqubo kungase kudingeke uhlelo sokuqalisa kabusha ngokugcwele.

Kungani Java akuxhomekile OS?

Njengoba sekushiwo, lolu limi libhekisela into-ngamakhasimende (efana C + / C ++, okuyinto zahlelwa-Windows).

Kodwa empeleni yayo ukuthi virtual Java-umshini uyakwazi adlulisele imiyalo izicelo elisebenzisekayo ku ekhethekile ibhayithi amakhodi obonwa yiluphi uhlelo nekhompyutha, kungakhathaliseki ukuthi umqambi walo. Ngokulinganayo ezinhle ukuthuthukiswa imvelo-Java izinhlelo isetshenziswa ku-PC, futhi Intel emsamo, futhi izinhlelo mobile-Android, i-Blackberry, iOS, kanye nabanye.

Ngo isofthiwe imvelo "OSes" kakhulu kukhona kakade esakhelwe wokumbulala ulimi umyalo. Futhi asisebenzi ezindaweni ezithile ezifana Microsoft .NET Framework noma omunye ukuthi abakhiqizi bayatfutfuka wokusebenza ukusebenza applets zabo.

kumadivayisi eselula

Kepha ngisho abavamile omakhalekhukhwini ngaphandle isistimu yokusebenza ebhodini, nabo has ukwesekwa yasekuqaleni lunga yesikhulumi. Ngokuvamile, ze sibe embizeni isandiso noma jad futhi ngempela aphansi efakwe ngisho amafoni lasekuqaleni.

Uhlelo ezisebenza ingasetshenziswa archivers ezifana WinRAR, okuyinto bona enjalo zomlando self-yokukhipha ezifana SFX-ifayela ngaphandle kwezinkinga. Uma uchofoza kabili kuleli fayela, okuqukethwe kuzosuswa ekhishwe ngokuzenzakalela yomlando yesikhulumi Java, kulesi simo usebenza ngemuva.

Yini engingayisho, ngoba ngisho imidlalo elidala efonini elula lingasethwa ngempela kalula. Nakuba kunenkolelo kulezi 'eziphambili "wokusebenza azisetshenziswa, akusiyo.

Ngisho ku izindlela ezindala njengesifo Nokia 3310 yesikhulumi. Uma bekungenjalo, bengiyakunitshela ukuthi ifoni isebenze? Kuhlelo efanayo njengoba isivele ecacile, futhi esakhelwe ukwesekwa, okuyinto unomthwalo Java ukuthuthukiswa imvelo.

Kepha thina imiyalo lisetjentiswe ekwakheni izinhlelo zokusebenza, incazelo yabo kungase kuthathe isikhathi esiningi. Kodwa uma umqondo yokudala isicelo ngokusekelwe ngalolu limi sisekhona, kungcono ukufaka uhlelo olukhethekile njenge platform ezihlinzekwa Delphi imvelo (isikhombimsebenzisi sokuqhafaza kuyafana).

isiphetho

Njengoba ubona, ukuthuthukiswa Java imvelo emhlabeni iyahambisana yiluphi uhlelo. Kodwa kuyasiza ngokushesha okuningi kunalokho imiyalo ukusakaza esekelwe C + / C ++. Ngokusho Olunye ucwaningo lwabonisa ukuthi ukusebenza angaba phezulu by izikhathi 20-30, nakuba ukusetshenziswa imemori ezingeni ibencono.

Kodwa uma ngamafuphi eminye imiphumela, kuyafaneleka yizinhlobonhlobo langempela anikezwa Java ukuthuthukiswa imvelo. Empeleni, ukuthi iyahambisana zonke izinhlelo, elenza ethandwa kakhulu ukwakha izicelo ezifanayo multimedia noma imidlalo.

Kufanele futhi ukuthi inguqulo yakamuva ye-Java kusekelwe ukusekelwa ejwayelekile amathuluzi izinhlelo, okuncike ubuchwepheshe Eiffel futhi C #, ngokuphelele ezahlukene kusukela esebenzisa C ++. Lapha ungasebenzisa ukuguqulwa okuzenzakalelayo scalar izinhlobo idatha futhi ukungenisa ezindaweni okuthiwa izinkundla static, ingasaphathwa kungenzeka yokudala imibhalo eyeseka nge ikhodi yomthombo.

I-Java SE 6 kuhlanganisa izici eziningi ezintsha, ezihlanganisa ngisho ukuqashelwa amakhalenda Japanese futhi Buddhist, ikhono ukwakha egcwele i-HTTP-iseva, ukudluliswa yashesha ekilasini-ukugeleza futhi idatha onomfutho ukuze kwandiswe umkhiqizo kufika ku-70%, ingasaphathwa kudeshibhodi JConsole VulaGL asekelayo iDirectX hardware.

Lokhu kusebenza ikakhulukazi ukuba ihluzo amakhadi, nakuba kungenzeka kubhekisela emaqenjini ukusetshenziswa ngisho idivayisi yomsindo (ngokuvamile umshayeli virtual ASIO4ALL isisekelo). Kuyefana nasendleleni abanye synthesizers software noma i-MIDI-ikhibhodi. Kodwa ukusetshenziswa Java-applets elisebenzisekayo akuyona njalo enikeziwe.
