Java-huānga o aho. Kōmaka i te ngohi i roto i Java. Ko te ngohi e rua-ahu o te Java

I roto i te mahi hōtaka, i reira e he rota o huinga rerekē me ngā momo o te raraunga e taea te rāwekeweke te pūnaha, me te ki e taea te kaihātepe whakarite ki tukatuka mōhiohio.

momo raraunga i roto i ngā reo hōtaka

Ko ha konga o te nuinga o ngā reo hōtaka, e whakaahua ana i te rahi me ngā āhuatanga o ngā raraunga penapena i roto i te wāhi mahara motuhake, e whakarite mahi tika o te hōtaka i roto i te tukanga o te whakatinanatanga i te mahi tikanga.

Hei tauira, tetahi o nga momo raraunga tefito he taurangi tau tōpū. Ka taea e waiho ratou hainatia e rua me te hurihia, rite te ingoa iho whakarato kē ngā mōhiohio i runga i te tirotiro o te pūtau taua.

I tua atu ki te taurangi tōpū, i reira he analogues o tau tere-ira e kua whakamahia ki te tohu rahinga tūturu. I te pae hopea, te tahito pera-ka karanga momo raraunga e string me huru taurangi, me atatohu. tahi Katoa ko reira he taratahi kōwae reo.

hanganga raraunga

whakaaro Higher hōtaka taumata whakahaere te ki hei te uniana o te maha wae momo raraunga i tahito ra ki te hanganga matatini ake. te noa tino ko te pera-ka karanga Java-huānga ngā momo hiato. Ka taea hoki te tīpako rārangi, tuples, ngā tāpae me rārangi.

Ko te rerekētanga matua o ngā huānga he e whakarato ratou uru tupurangi ki ona āhuatanga. Heoi, takoto te uaua i roto i te meka e kia waiho te rahi taea ki te tohu tika te hanganga arawhiti wāhanga. whakakorea tenei ngoikoretanga e i roto i te momo raraunga matatini ake, hei tauira, i roto i te rārangi. Taua pūnaha i te kaha ki te hihiri whakawhänui ki te tua o ngā huānga hou, engari uru ki te raraunga i roto i a ratou e wa ake.

I roto i te nuinga o ngā reo hōtaka hou, e reira enei hanganga katoa me te tākaro i te wāhi tino hira i roto i te mahi o ngā tono e rua me te rauwiringa kaiao ano. Na Java - he kahore okotahi.

Ko te reo papatono Java. wae matua

Java Ko te bytecode reo hōtaka kaha pato e rere i roto i te mīhini mariko e taea ki a koe te mahi ngā mahi, me te whiwhi i te hua taua ahakoa o te hoahoanga rorohiko me ngā pūnaha whakahaere.

Ko te tuku hou o te reo Java kua waru momo tahito: pūreana boolean, tōpū paita, tau tōpū, poto, roa, momo o tau tere-ira, faahoho'ahia e te manu, me te rua, me te pūāhua char.

Java-ngohi, ko te kohinga o tetahi momo o raraunga kei roto i te mahara o ia atu, me te mea he tau raupapa (taupū) e e taea te kaihātepe te pūnaha ranei te uru i te tūemi takitahi rongoa i roto i te ngohi. tīmata Tataunga ki te taupū kore (te huānga tuatahi) me te incremented mo ia tetahi muri. I te taua Java-ngohi whakarato uru tupurangi ki raraunga - waehere kaiwhakamahi e taea te uru tetahi huānga o te ngohi, ahakoa o tona wāhi i roto i te hanganga.

ahanoa

Kaua e wareware e Java - ko matua he reo hōtaka ahanoa-hāngai. Na reira, enei āhuatanga ko te wāhi o te tauira mahara. Ka taea te huaina te taa o tenei momo o te pūnaha e-te taea rokiroki huānga Java ahanoa i te ara ano rite pupuri ratou i nga momo raraunga i tahito ra. Ko te kaupapa tino noa i roto i te reo, he aho. tohu ratou nga huinga pūāhua, whakaritea ki te mahara kotahi, me te puta ke tana mahi.

Java Ko te ngohi o te aho whakahau huinga o atatohu ki ētahi atu wāhi mahara i roto i ia o e rongoa te ahanoa rapu te. Ko te hiahiatia whakaturia o pūāhua te kaiwhakamahi ko, reira, i te wāhi mamao i roto i te mahara o te mīhini mariko me mahi ki reira autaki.

huānga e rua-ahu (tāhū,)

he āhuatanga pēnei, rite te kopu, ko te rua-ahu ngohi o te Java-taonga primitives ranei, te whakarite ki a ratou i runga i te "maha o te tīwae." Kei te te tahi mau taime fakamatala'i tenei hanganga raraunga hei "ngohi o huānga". Ko e tika ana ki te meka e ia haupae tīwae ranei tūemi kei roto i ngohi Java-ahu mania tenei, me to ratou huinga ko te kopu.

I roto i te whakatinanatanga rua-ahu, kia whai tona roa ake rerekē i te toenga ia o nga pere. A, no te faahiti ki te huānga kotahi o te ngohi mā te whakamahi i rua taupū ki te tohu i te wāhi mahara e hiahiatia ana. Tuatahi - Ko te tau aho, i te mea te ahanoa e hiahiatia ana tenei. Ko te taupū tuarua - ko te tau tīwae, te tau rangatū o te huānga i roto i te pere ranei. huānga fakahokohoko roto te hanganga e rua-ahu tīmata ki te kore, pera i roto i te take o ngā huānga kotahi-ahu. Na reira, ki te whakatutuki ka whakamahia te huānga whakamutunga o te roa ngohi N pūāhua taupū [N-1].

tūemi Kōmaka

Ko te raruraru tino noa, ka mahi ki te huānga, ko ïa te ahua. mama i mawhiti tuatahi tenei, riro nui atu uaua rite te maha o ngā huānga i roto i te pere poukapa ranei te mahi.

He maha hātepe rerekē mō te kōmaka huānga i roto i te hanganga i homai - Tikanga mirumiru kōmaka tauira pai rawa whakaurunga tikanga hononga ranei. rerekē tikanga katoa i roto i te tere o te mahi, me te nui o te mahara e hiahiatia ana mō te pupuri atu raraunga me ngā hua rangitahi i roto i ngā mahi takawaenga.

kia whai ētahi hātepe rerekē ōwehenga tino pai i runga i te huinga tāuru raraunga rānei. I roto i te Java kia whakamana ngohi kōmaka i te tikanga o te Arrays piha kaiawhina paerewa, e kua he ahua tikanga pateko, kōmaka huānga i roto i te tikanga e piki mā te whakamahi i te tīpako nohopuku. Heoi, he iu te hātepe, a kia rere tona wa mahi ara i roto i te tukatuka o huānga o te roa rite. mohiotia tenei te rite te kōmaka tere hoki whakahau rārangi nui tupurangi. E wātea ana hoki hötaka nga moni katoa mo te whakatutukitanga o tetahi atu hātepe kōmaka i runga ki te tawhā o te raruraru me ngā whakaritenga ki te hua.
