Kulo okuthunyelwe Amakilasi nezinto eziseJava, okungolimi lohlelo, kuyashiwo izincazelo zalo, kuyimiqondo enentshisekelo kubafundi abanentshisekelo kumvelo yekhompyutha.
Amakilasi nezinto eziseJava
IJava ulimi lokuhlela kanye nesikhulumi sekhompiyutha esisetshenziswa ezinhlelweni eziningi nakumawebhusayithi, ngokususelwa kulo mqondo sizobona ukuthi amakilasi nezinto eziseJava. Udinga ukwazi izisekelo zohlelo oluqondiswe entweni: izinto namakilasi.
Sincoma i-athikili efanelekile ngale ndaba Ungayisebenzisa kanjani iJava.
Amakilasi
Isigaba simele uchungechunge lwezinto ezingenelela esakhiweni futhi esiziphatha ngezimpawu ezifanayo. Isigaba siyinhlanganisela ekhethekile yezimpawu nezindlela, futhi sithathwa njengohlobo lolwazi lwanoma iyiphi into evela kumsuka wayo.
Ngakho-ke, isigaba yisifanekiso noma ifomethi yohlobo lwezinto: sichaza izimfanelo abazakha kulezi zinhlobo zezinto nezindlela ezingasetshenziswa ukuphatha izinto. Isigaba kulapho kuchazwa khona izakhiwo nezindlela isimo ngasinye sezinto.
Emakilasini ungasho isibonelo sethelevishini, siyazi ukuthi kunezinhlobo ezahlukene zamathelevishini futhi ngayinye inezici zayo. Kodwa-ke, banesikimu noma amapharamitha afaka i-TV, lokhu kwaziwa ngokuthi isigaba.
Izinhloso
Yibhizinisi elikhona kwimemori yekhompyutha eliqukethe izakhiwo, okungukuthi, izimfanelo noma idatha yazo futhi zigcinwa kungobo yomlando ngento ethile, nakweminye imisebenzi ekhethekile etholakalayo.
Ngemuva kwalokho ingachazwa njengengxenye yesoftware ehlose ukumela into endaweni yangempela, ukuze into ibe nezakhiwo nezenzo okufanele zenziwe nento leyo.
Izici nezenzo kufakwe ngaphakathi kwento, kwenziwa imigomo yokugoqelwa. Uhlobo olususelwe entweni lubukeka njengokuphambene nohlelo oluhlelekile obelusetshenziswa kusukela ngawo-60.
Into inesimo sayo, noma ithi kanye nokuziphatha kwayo, okulungiswa ngezakhiwo noma okuguqukayo nezindlela. Eqinisweni, into ingaba nolunye uhlobo lwento ngasikhathi sinye.
Kuyini ukufakwa kwedatha
Ukusebenzisana nezinto kwenziwa ngezindlela, okusho ukuthi uma ufuna ukwazi imininingwane ngesimo sento, kufanele ubheke enye yezindlela hhayi ngqo kuzakhiwo.
Ukufakwa ngaphakathi kuvumela ukuguqula izakhiwo zento ngaphandle kwesidingo sokuthi abathengi bathinteke, inqobo nje uma beqhubeka nokuletha umkhiqizo ofanayo, okungukuthi, umphumela.
Ngempela, kunezinto ezinempahla yomphakathi, ngakho-ke zingafakwa ngqo, ngaphandle kokusebenzisa indlela.
Ukusebenzisa izinto kunikeza izinzuzo ezilandelayo:
- Modularity, lokhu kusho ukuthi into nezakhiwo zayo kungahlanganiswa yizinhlaka ezahlukahlukene zekhodi yomthombo, kepha into ihlala ifana.
- Ukuhlanganisa idatha, kufihla ukwenziwa kwezinto zento, ngoba ayifakwanga ngezindlela zento.
- Ukusetshenziswa kabusha kwekhodi, ungathola izimo ezahlukahlukene zento, ukuze lezo zimo ezahlukahlukene zabelane ngekhodi efanayo.
- Ukufaka esikhundleni, okusho ukuthi ungashintsha enye into ufake enye, inqobo nje uma lezi zinto zinokusebenza okufanayo.
Ezinye izibonelo zezinto
Noma yimuphi umqondo endaweni yangempela ungamodeliswa njengento enesimo nokusebenza kwayo, ngokwesibonelo icala lamanje yileli: Ithelevishini iyinto, futhi izifundazwe eziyibhalayo: zivuliwe, zivaliwe, zilungiselelwe isiteshi 1, zilungiswe esiteshini 2, ukuqopha. Manje, izenzo yilezi: "vula ithelevishini", "cisha ithelevishini", "shintsha isiteshi", "qala ukuqopha".
Sizokhuluma ngesinye isibonelo, sicabanga ukuthi kunesibalo sejiyomethri esingaba unxantathu, lesi sibalo singacatshangelwa ngezinto ezahlukahlukene ezinjenge: isisekelo, ukuphakama, uhlangothi no x, y ukuxhumanisa kwesikhungo unxantathu.
Uma sizobheka kunxantathu, singakwazi “ukubala indawo kanxantathu”, “ukubala umkhawulo wonxantathu”.
Umehluko phakathi kwesigaba nento
Isigaba yisibonelo esichaza okuguqukayo nezindlela, imisebenzi ejwayelekile kuzo zonke izinto zohlobo oluthile.
Into iyimodeli yesigaba, izinto zesoftware zivame ukusetshenziselwa ukumodela izinto endaweni yangempela ekhona empilweni yansuku zonke.
Kufingqa lokhu okuthunyelwe, kungashiwo ukuthi iClass in Java iyinhlangano enquma ukuthi into iziphatha kanjani, ngaphezu kokuqukethwe kwayo. Into yinto ezimele esuselwa kuzindlela nezakhiwo ukuthola imininingwane ethile.
Uhlelo lwesigaba lunomsebenzi wokuvumela uhlelo ukuthi lucacise isigaba esisha ngokususelwa esigabeni esivele sikhona.
