Mayelana nalolu hlelo lokusebenza

Lolu hlelo lokusebenza Kuyini iKotlin, Izifundo zeKotlin, Amasampula eKotlin neKotlin noma iJava? Siqukethe izingxenye.
Ungasebenzisa lolu hlelo lokusebenza, lapho ungafinyelela khona eminye imininingwane nemininingwane mayelana nolimi lwaseKotlin, nganoma yisiphi isikhathi.

IKotlin yadalwa yinkampani yakwaJetBrains ngo-2010.
UKotlin wamenyezelwa emcimbini we-JVM Language Summit ngoJulayi 19, 2011.
I-Kotlin wulimi lohlelo lwe-static.
IKotlin yiphrojekthi yomthombo ovulekile eyenziwe ngaphansi kwelayisense le-Apache 2.0, evulekele ukwesekwa nosizo.
Ikhodi yomthombo yephrojekthi ivulekele wonke umuntu. Ungenza ngcono ukusekela iphrojekthi. Ukubuyekeza nokusekela iphrojekthi, ungavakashela iGithub: https://github.com/jetbrains/kotlin
Ukuthuthuka kokuqala kukaKotlin kwenziwa ngabathuthukisi besoftware bakwaJetBrains, inkampani ezinze eRussia. Igama likaKotlin livela esiqhingini saseKotlin eRussia.


1) I-Kotlin ulimi lwamahhala lokuvula ikhodi lwamakhodi womthombo athuthukiswe ngokwezibalo ngaphansi kwelayisense le-Apache 2.0. Ungasekela ulimi lwaseKotlin futhi ubambe iqhaza ekuthuthukiseni iKotlin.

2) I-Kotlin ulimi olusebenzayo oluqondiswe entweni. Ulimi lohlelo oluqondiswe entweni olufana neJava, C # kanye ne-C ++.

3) I-Perl ne-Unix / Linux isekela ukungeza entanjeni yesitayela se-Shell script.

I-4) IKotlin imfishane futhi icacisiwe kuneJava. Isici esibaluleke kunazo zonke esijabulisa nokuheha abahleli bohlelo ukuthi ilula futhi ihlukile.

5) IKotlin isebenza nge-100% ehambisana neJava ne-Android. NgeJava, iKotlin ingacatshangwa njengengxenye ye-apula.

6) IKotlin ilulimi oluphephe kakhulu kuneJava. Manje kusho ukuthini lokhu kuvikeleka? Idatha yeNull, ebisetshenziswa ezinhlelweni ezigxile ezintweni kusukela ngo-1965 futhi yabangela ukulimala okuyizigidigidi zamaRandi, yaphathwa ngokuphepha kakhulu neKotlin futhi yavinjelwa ekulimaleni uhlelo. Kufanele wenze umzamo okhethekile wokuthola iphutha le-Null eKotlin :)

7. Ixhasa ukuthuthukiswa kweseva nezinhlelo zokusebenza ezisekelwe kumakhasimende.

8. Ihlanganiswe ngamakhodi weJavaScript futhi isetshenziswe emakhasini e-HTML.
Uma unesithakazelo ezilimini ezisetshenziswa kuwebhu njengeJavascript ne-HTML, ngicabanga ukuthi iKotlin ulimi ongaluthanda.

9. IKotlin neJava ziyasebenzisana. Ungasebenzisa iKotlin eJavan naseJava eKotlin. Ungahumusha kalula ikhodi yeJava oyibhale ku Android Studio ngolimi lwaseKotlin.

10. IKotlin inika amandla ukuthuthukiswa kohlelo isebenzisa imitapo yolwazi ekhona yeJava. Isebenza ngeJava. Akunakubhekwa ngokuzimela kweJava.

11. Into ebaluleke kakhulu egqamisa ulimi lwe-Kotlin: Isigaba se-Android Developer se-Google Company siyaluthemba lolu limi futhi silusekele ukuthuthukisa izinhlelo ze-Android.

Ngolimi lohlelo lweKotlin, ungathuthukisa izinhlelo ezahlukahlukene kuzingxenyekazi ezinkulu ze-4 noma izindawo. Izindawo zentuthuko zibalwe ngezansi.
I-JVM: Izicelo eziseceleni kweseva
I-Android: Izinhlelo zokusebenza ze-Android
Isiphequluli: Izicelo zewebhu ezisuselwa kuJavaScript
Okomdabu: Izicelo zezinhlelo ze-MacOS, iOS nezinhlelo ezishumekiwe. (Ngaphansi kokuthuthukiswa.)

a) Ukulungiswa kukaKotlin kokunye ukushiyeka kuJava:
Ihlola izinkomba ezingenamsebenzi,
Alukho uhlobo lwedatha eluhlaza,
Ukuhlelwa akuguquki
Kunezinhlobo ezifanele zemisebenzi.
Akuhloli okuhlukile.

b) Izici ezingekho kuJava neKotlin:
Ukuphepha okungenamsebenzi
Ukusakaza okuhlakaniphile
Izintambo zezintambo,
Izici,
Abakhi bokuqala,
Ibanga,
Ukulayisha ngokweqile kwe-opharetha
Amakilasi Wedatha
Ngeminye imininingwane, ungavakashela ikhasi elisemthethweni laseKotlin:

c) Izici kuJava kepha hhayi eKotlin
Ukulawulwa Okuhlukile
Izinhlobo Zedatha Yokuqala
Amalungu Aqinile
Izinhlobo zeJoker
I-Ternary Operator
