Ngaba uyawazi umahluko phakathi Kotlin vs. Java? Ukuba uzinikele ku inkqubo apps Android, iJava isenokuba lulwimi lokuqala olufundileyo. Kodwa ngoku Kotlin nayo ihamba ngamandla.
Ke ngoko, kulula kuwe ukuba ungaqinisekanga ukuba yeyiphi kwezi lwimi zimbini ilungele iimfuno zakho. Nangona okona kulungileyo kuya kuba kukukwazi zombini kwaye usebenzise le uyidingayo ngamaxesha onke. Kodwa inyaniso kukuba oku kungathatha ixesha elide. Ukukunceda kancinci, siza kubona iimpawu zomntu ngamnye. Ke, ukukwazi ukukhetha eyona ndlela ilungileyo xa ucwangcisa usetyenziso lwe-Android kwaye ufumane i ulwimi olufanelekileyo.
Kotlin vs Java, khetha ulwimi lwakho ukucwangcisa usetyenziso lwe-Android
Ukuze sijongane neKotlin vs Java, siqala ukubona iimpawu zomntu ngamnye.
Ulwimi lwenkqubo yeJava
IJava lulwimi lwenkqubo apho singenza khona naluphi na uhlobo lwesicelo. Sinokuwusebenzisa kulo naluphi na uhlobo lomatshini. Ikwiinkqubo zokusebenza zeWindows, Linux kunye nakwi-Android. Isimahla, kwaye yenye yezona zinto zibalulekileyo kwihlabathi lekhompyuter kunye nenkqubo. Ke ngoko, inoluntu olukhulu lwabasebenzisi.
NgeJava unokucwangcisa yonke into onayo engqondweni. Lulwimi olusoloko lusetyenziswa kuphuhliso lwamaphepha ewebhu. Kwaye nakwiinkqubo zokuvota kwiinkampani. Yinkqubo esetyenziswa ngokubanzi kuphuhliso lwezicelo ze-Android. Kodwa ukuba ungumqali, ungaqala ngokwenza inkqubo elula kakhulu.
IJava yenye yeelwimi ezihlala zibuzwa kuyo umphuhlisi umsebenzi inikeza. Ngoko ukufunda nokuyiqonda kunokukunceda kakhulu kwimarike yomsebenzi.
Izinto eziluncedo kunye nezingeloncedo kwiJava
Inzuzo yayo ephambili kukuba ungayisebenzisa ukucwangcisa yonke into onokucinga ngayo. Hayi kuphela kwicala lomxhasi, kodwa nakwi-End-End. Kwaye lulwimi oluzimeleyo, ke uya kuba nakho ukulisebenzisa phantse kuyo nayiphi na ikhompyuter.
Ngokuphathelele ukungonakali kwayo, eyona nto iphambili kukuba ayilolwimi lwanamhlanje. Java 8 ithathe inyathelo elibalulekileyo ngokwemigaqo yeempawu ezintsha, kodwa ayihambelani nenkqubo ye-Android. Ukuba ufuna ukucwangcisa usetyenziso, kuya kufuneka uzinze kwiJava 7.
Sinokuthi iJava lulwimi ekufuneka wonke umntu ofuna ukuzinikela kwihlabathi lekhompyuter alwazi. Ukuguquguquka kwayo okukhulu kunye nokusetyenziswa kwayo kwiinkqubo ezahlukeneyo zokusebenza. Uluntu lwayo olukhulu lusenza ukuba ibe lolona lwimi lubalulekileyo ehlabathini. Kodwa ukuba awukhuphi izinto ezintsha, zale mihla, unokuba usalela ngasemva. Kwaye kulapho kanye iKotlin ingena khona kumhlaba wenkqubo.
Kotlin ulwimi lwenkqubo
Kotlin lulwimi lwenkqubo oludalwe yiJetBrains. Kwabhengezwa kuGoogle I/O njengolwimi olusemthethweni lwenkqubo yezicelo ze-Android. Ezinye zimbini yiC ++ kunye neJava ekhankanywe ngasentla, mhlawumbi eyona idumileyo.
Lulwimi oluvulelekileyo, oluphantsi kwelayisensi ye-Apache 2.0. Abaphuhlisi bayo bayaqinisekisa ukuba iya kubonelela ngendlela elula neyonwabisayo yokucwangcisa usetyenziso lwe-Android. Ngayo, ezinye iiprojekthi ezinomdla njengePinterest okanye iFlipboard ziye zaphuhliswa, eziye zaba yimpumelelo epheleleyo. Konke oku xa esathatha phantse amanyathelo akhe okuqala.
Izinto ezilungileyo zeKotlin
Enye yeenzuzo ezinkulu zeKotlin kukuba inokwenza iifowuni kwiJava kunye nokunye. Ngoko ke, asilolwimi esisoloko silusebenzisa sodwa. Ngokuchasene noko, siya kukwazi ukuyenza ngokuhambelana nolwimi olukhankanywe ngaphambili, nayo yonke loo nto ithethwayo.
Enye ingenelo ebangel’ umdla kukuba lulwimi zangoku. Ke ngoku akunakubakho mahluko ungako. Kodwa kancinci kancinci siya kubona ukuba iKotlin ibandakanya njani izinto ezintsha ezinokwenzeka. Ezo zingafumanekiyo kwiJava. Uluhlu olunokwenzeka lwandiswa.
Ukungalungi kweKotlin
Eyona nto ingalunganga esiyifumanayo kukuba lulwimi olutsha kakhulu. Oku kwenza kube nzima ngakumbi okwangoku ukufumana ulwazi lokuphuma kuyo nayiphi na ingxaki.
Nangona kunjalo, kukho iindawo ezininzi apho sinokufunda khona iKotlin. Ngaphandle kwezifundo zemveli, iiwebhusayithi ezininzi kunye neeblogi ziyavela ezijolise ekuvavanyeni olu lwimi.
Kule nto sinokufumanisa ukuba ukusebenzisa i-Kotlin kuya kuthetha wena ngokomgaqo umzamo owongezelelweyol. Kodwa wakuba uziqhelanise nolwimi olutsha, uya kukwazi ukufikelela izinto ezintsha ezinokwenzeka. Kwaye uluntu lwayo lukhula ngakumbi nangakumbi, oko kuthetha ukuba ulwazi lufumaneka ngakumbi nangakumbi.
Ngoko ke yeyiphi engcono? Java vs. Kotlin
Inyani yeyokuba isiKotlin lulwimi oluphucuka mihla le. Kwaye kwimiba efana nokhuseleko, i-syntax, ukuhambelana, kunye nenkqubo esebenzayo, iqhuba ngcono kakhulu kuneJava. Kukwakhawuleza kancinci, ke ukwakha iprojekthi kuya kuthatha ixesha elincinci kakhulu.
Ingxaki kuphela ngeKotlin sisidingo sokufunda ulwimi olutsha. Uninzi lwabadwelisi benkqubo bathetha ngokugqibeleleyo kwiJava. Kwaye ukuziqhelanisa nombono wokufunda ukusuka ekuqaleni ukwenza iiapps zethu ngolunye ulwimi kunokothusa kakhulu.
Nangona kunjalo, khumbula ukuba zombini iilwimi zinesiseko esifanayo. Ngoko ke, i ijika lokufunda iyakuba ngokukhawuleza kakhulu ngexesha ufumana ukusebenza noKotlin ukuba ubusele usebenzisa iJava ngaphambili. Kwaye xa sele uluqhelile ulwimi olutsha, unokuthelela ekubeni lungcono kakhulu kunolo ubulusebenzisa ngaphambili.
Ewe, kwizinto ezikhethwayo xa udwelisa akukho nto ichaziweyo. Kwaye kuya kubakho abaphuhlisi abasakhetha ukusebenza kwiJava. Ke ngoko, kungcono ukuba uzame kwaye ukhethe eyona ifanele iimfuno zakho.
Ngoku sijongene Kotlin vs. Java, ungasinika uluvo lwakho malunga nezi lwimi zokucwangcisa. Iilwimi zokucwangcisa usetyenziso lwe-Android. Kwaye ungashiya uluvo lwakho apha ngezantsi.
