Nei uchichinja kubva kuJava uchienda kuKotlin kune Android app kuvandudza

Nyika yakagadziridzwa muNguva yanhasi uye Mitauro ine basa rakakura mune izvi. Kune marudzi akasiyana emitauro yakaita seC, C++, Java, Python uye zvakawanda zve Kukudziridzwa kweApp. Nokushandisa mitauro iyi, munhu anogona kuita basa iri nyore uye nekukurumidza. Muchikamu chino, tichakurukura nezve Kotlin Mutauro wechirongwa une masimba ane simba zvakanyanya sekuenzaniswa nemutauro weJava. Kana paine munhu anotoziva Java, kudzidza Kotlin zviri nyore kwazvo kwavari. Kotlin mutauro mutsva wekugadzira uye unosanganisira mutengi, webhu, server, uye Android budiriro

Kana isu tave kutoshandisa Java, Kotlin Mutauro wekuronga unogona kushandiswa zviri nyore nekuda kwekuwanikwa kwawo chaiko. Kotlin mutauro wechirongwa unoshandiswa muJava Virtual Machine (JVM). Kotlin mitauro yepurogiramu inoshandiswa mu Android kuvandudza kweApp.

Nei uchichinja kubva kuJava uchienda kuKotlin

nhasi, Kotlin mutauro wepurogiramu ndiyo yekutanga sarudzo ye Developers kugadzira Android mafomu. Developers vari kubva kuJava kuenda Kotlin programming mutauro nekuda kwezvimiro zvayo. Zvisinei, Kotlin inogona kushandiswa chero kupi, uko java iri kutoshanda. Pazasi pane zvimwe zvikonzero nei chero munhu achifanira kubva kuJava kuenda Kotlin.

Kubva paJava

Kotlin iMutauro wePurogiramu une simba kwazvo uyo wakavakirwa papuratifomu yeJava uye nharaunda. Iye zvino mutauro uyu wakashandiswa mumapurojekiti mazhinji uko Java yave kutoshandiswa. Saka mutauro uyu uri nyore kunzwisisa nawo Developers pamapurojekiti ese uye anogona kumhanya zviri nyore pamutauro uyu mushe.

Kodhi Conciseness

Kana isu tichienzanisa Java kodhi ne Kotlin Code, tichawana zvishoma kukodha in Kotlin programming mutauro kugadzira chero chirongwa. Kazhinji, Developers inoda kutsanangura akati wandei minda yekuchengetedza iyo data, setter uye getter mabasa eminda uye zvimwe zvakawanda kukodha, Asi mu Kotlin Mutauro weChirongwa, mugadziri anofanirwa kuisa data kiyi izwi mukirasi mumutsara mumwe chete unoderedza iyo kukodha uye inochengetedza nguva nesimba.

Chirongwa Chakajairika

Iyo yekutanga chimiro uye syntax iri nyore kwazvo uye inojairika Kotlin Mutauro wechirongwa nekuti uyu mutauro wakavakirwa paJava. Saka Developers avo vanotojairana neJava vanogona kugadzira mapurogiramu nyore nekushandisa Kotlin sezvo vachigona kunzwisisa uye kugadzirisa zvikanganiso zviri nyore.

Null Kuchengetedza

Kana isu tikashandisa zvinosiyana muJava, nekusarudzika zvese zvinonyarara kusvika uye kunze kwekunge zvakamisikidzwa seyekupedzisira. Asi mu Kotlin Mutauro tine sarudzo yeizvi. Tinogona kutsanangura zvinoshanduka se isingachinjiki sevhavha kana isingachinjiki sevar munguva Kotlin kunyora.

Auto Inokanda

Chimwe chezvikonzero zvakasimba zvekutama kubva kuJava kuenda Kotlin is Auto Casts. Kotlin Mitauro yekuronga haidi chero cheki kana bvunzo kuti uteedzere chinhu chimwe chete seCompiler mukati Kotlin Chirongwa chinoshandiswa kutevedzera otomatiki makanda. Inovandudza kushanda zvakanaka uye inoderedza nguva mune chero budiriro. Ichi ndicho chikonzero nei Kotlin inoshanda zviri nyore mumapurojekiti uko Java yatove kushandiswa.

Kuisa tambo

Tambo mune chero mitauro mitauro inoshandiswa pamhando dzese mitauro yekuronga.

 Iyo tambo imwechete inoshandiswa muJava inogona kushandiswa mukati Kotlin Mutauro wechirongwa zvakare, izvo zvinoita kuti zvive nyore uye kujaira kune chero shanduko mukati kukodha.

Tsananguro nePfuma

In Kotlin tinogona kuwana zvivakwa zvakawanda nekushandisa chete set in Kotlin Mutauro wepurogiramu. Mutauro uyu une zvimiro zvakapfava zvekupinza nekubuda. Saka, zviri nyore kwazvo kuisa mapindiro nekuashandura uye zvinoita kuti Kotlin ive Mutauro unoshanda.

Kupokana uye Kuenzana

Sezvo isu taziva mumutauro uno kuti Kotlin inozivikanwa kwazvo uye Mitauro yakapfava, Iko hakuna kudikanwa kweKuwedzera kana ruzivo rwakakosha rwezviratidzo zvinoshandiswa mumutauro uyu. Nekudaro uyu mutauro uri nyore kwazvo kudzidza uye kushandisa mune chero chirongwa.

mhedziso

Kune akawanda akawanda maficha emutauro weKotlin kunze kwemashoko ataurwa pamusoro apa. Kotlin anoshandisa asiri-null marudzi uye null type zvirevo. Chiziviso, Range, uye Mabasa akafananawo mune mimwe mitauro. Sezvo tichigona kushandisa mutauro weKotlin nemimwe mitauro, zvinobatsira kuwana mhedzisiro iri nani. Mutauro unobatsira zvikuru nekushandisa mitauro yekare yekuronga. Developers inogona kukudziridza inoshanda zvakanyanya Android Apps uchishandisa mutauro uyu.
