Ukunciphisa iSambuku yingxaki eqhelekileyo ejongene nabaphuhlisi abaninzi kunye nabathanda inkqubo ngokufanayo. Ifuna ukuqonda okusisiseko kweekhonsepthi zokucwangcisa. Nangona iJava ibonelela ngeendlela ezahlukeneyo zokusombulula le ngxaki, isenokuthi ibe ngumsebenzi odidayo kwabanye. Kweli nqaku, siza kuhlolisisa esinye sezona zisombululo ezisebenzayo kwiNgxaki yokuNcitshiswa kweSum kwiJava, sichaza inxalenye nganye yekhowudi ngesinyathelo-ngesinyathelo, ngokwenza ukuba iqondakala lula nakubaqalayo.
Ukunciphisa Ingxaki Yemali
Ingxaki yesambuku yokunciphisa ifikelela ekushwankatheleni amanani kumjelo wamanani. Ingxaki ingaba neenguqu ezahlukeneyo. Isenokuba ziziqalelo ezishwankathelayo zoluhlu, iziqalelo zoLuhlu oluDityanisiweyo okanye iziqalelo ezishwankathelayo zoMjezo kwindawo enemisonto emininzi esebenzisa `umsinga.nciphisa()` umsebenzi. Isebenzisa iintetho ze-lambda kunye nojongano olusebenzayo, eziyimpawu ezibalulekileyo zeJava 8 nangaphezulu.
Isisombululo seJava
IJava ibonelela ngothotho lwamathala eencwadi kunye nemisebenzi ukusingatha ngokulula kunye nokusombulula ingxaki. Siza kusebenzisa i-Stream API eye yaziswa kwiJava 8. Ngokukodwa, indlela `yokunciphisa()` edibanisa izinto zomsinga ukuze ivelise isishwankathelo esinye sesiphumo.
Nantsi isampuli yekhowudi yeJava yokwenza njalo.
public int sumOfArray(Integer[] numbers) {
return Arrays.stream(numbers)
.reduce(0, Integer::sum);
}
Inkcazo ngamanyathelo ngamanyathelo yeKhowudi
Le khowudi ingasentla imele indlela ethatha uluhlu lwee-integers njengempikiswano kwaye ibuyise isimbuku sezi integu.
- Kuqala, `Ii-Arrays.umsinga(amanani)` iguqula uluhlu lube nguMsinga.
- Indlela `nciphisa()` ibizwa ngoku kulo msinga. Le ndlela ithatha iiparamitha ezimbini: ixabiso lokuqala lesambuku kunye nendlela emayisetyenziswe ekubaleni isixa.
- Ixabiso lokuqala kulo mzekelo limiselwe njenge ‘0’ kwaye indlela esetyenziswayo ithi `Inani elipheleleyo::sum`. `Inani elipheleleyo::sum` lisalathiso kwindlela engatshintshiyo `isixa' kudidi olupheleleyo. Le ndlela ibuyisela isimbuku seengxoxo zayo. Igqithiswa njengendlela yokubhekisela kwindlela yokunciphisa.
- `Nciphisa()` umsebenzi emva koko wenza udibaniso lomsebenzi kwinto nganye kumlambo kwaye isiphumo siyabuyiswa njengesiphumo somsebenzi.
Amathala eencwadi eJava kunye neMisebenzi efanayo
IJava ibonelela ngoluhlu olubanzi lwamathala eencwadi anokukunceda ukuba ulawule kwaye usebenze kwimisinga. Imisebenzi efanayo `ukunciphisa` iquka `ukuqokelela`, `ukubala`, `thelekisa`, `fumana`, `phinda` phakathi kweminye, ngokusekelwe ekubeni wowuphi umsebenzi ekufuneka wenziwe kumsinga.
Ngalo mzekeliso, siyakwazi ukubona ukuba iJava ibonelela ngezixhobo ezinamandla neziguquguqukayo zokusombulula iingxaki ezintsonkothileyo, njengokuba nengxaki yokunciphisa isixa. Bubungqina bokuguquguquka kunye nokomelela kolwimi.
