Hauv kev ua haujlwm, peb siv cov npe los khaws cov kab ke ntawm cov ntaub ntawv cuam tshuamPeb feem ntau xav ua tib yam haujlwm ntawm txhua lub ntsiab lus hauv ib daim ntawv teev npe, xws li tso tawm txhua lub ntsiab lus lossis hloov lawv ua lej.. Txhawm rau ua qhov ntawd, peb tuaj yeem siv lub voj los ua kom rov ua dua txhua lub ntsiab lus, rov ua tib txoj cai rau txhua lub caij.
Vim li cas peb thiaj siv iteration?
Vim li cas kev rov hais dua tseem ceeb? Iteration tso cai rau peb ua kom yooj yim peb cov algorithm los ntawm kev hais tias peb yuav rov ua qee cov kauj ruam kom txog rau thaum hais lwm yam. Qhov no ua rau kev tsim cov algorithms sai thiab yooj yim dua vim tias lawv tsis tas yuav suav nrog ntau cov kauj ruam tsis tsim nyog.
Yuav siv li cas?
suav-tswj loops - siv rau iterating cov kauj ruam ib zaug. Nws yog siv thaum tus naj npawb ntawm iterations coj qhov chaw twb paub lawm. Nws siv lub txee kom taug qab pes tsawg zaus cov lus txib tau rov ua dua. Count-controlled loops raug tua siv rau cov nqe lus.
Vim li cas peb yuav tsum siv iterator hauv Java?
Iterator hauv Java yog siv los hla txhua qhov thiab txhua yam hauv kev sauSiv nws, hla, tau txhua lub caij lossis koj tuaj yeem tshem tawm. ListIterator ncua Iterator tso cai rau bidirectional traversal ntawm ib daim ntawv teev npe, thiab kev hloov kho cov ntsiab lus. Txoj kev iterator yog muab los ntawm txhua chav Collection.
Thaum twg koj yuav tsum siv iterator?
5 Teb. Raws li koj tau hais iterator yog siv thaum koj xav tshem tawm cov khoom thaum koj rov hais dua cov ntsiab lus array Yog tias koj tsis siv iterator tab sis tsuas yog muaj lub voj thiab sab hauv nws siv qhov tshem tawm txoj kev koj yuav tau txais kev zam vim hais tias cov ntsiab lus ntawm cov array hloov thaum koj iterate los ntawm.
