Klašu, saskarņu, metožu un mainīgo nosaukšanai Java ievēro kamieļu reģistra sintakse. Ja nosaukums ir apvienots ar diviem vārdiem, otrais vārds vienmēr sāksies ar lielo burtu, piemēram, maxMarks( ), LastName, ClassTest, noņemot visas atstarpes.
Ir divi Camel korpusa izmantošanas veidi:
- Mazais kamieļa burts, kur pirmā vārda pirmā rakstzīme ir ar mazo burtu. Šo konvenciju parasti ievēro, nosaucot metodes un mainīgos. Piemērs, vārds, uzvārds, actionEvent, printArray() utt.
- Kamieļu augšējais burts, kas pazīstams arī kā virsraksta burts, kur pirmā vārda pirmā rakstzīme ir ar lielo burtu. Šī konvencija parasti tiek ievērota, nosaucot klases un saskarnes. Piemēram, Darbinieks, Drukājams utt.
Parastas virknes pārvēršana kamieļa futrālī
Virkni var pārvērst par apakšējo vai augšējo kamieļa korpusu, vienkārši noņemot no virknes atstarpes.
Apakšējā kamieļa korpusa piemērs:
Ievade: JavaTpoint ir labākā programmēšanas valodu apmācības vietne.
Izvade: javaTpointIsTheBestTutorialSiteForProgrammingLanguages.
Augšējā kamieļa korpusa piemērs:
Ievade: šī ir java apmācība
Izvade: ThisIsTheJava Tutorial
Algoritms:
- Pārvietojiet rakstzīmju masīvu pēc rakstzīmes, līdz tas sasniedz beigas.
- Virknes pirmais burts ar indeksu = 0 tiek pārveidots par mazajiem burtiem (kad seko kamieļu mazajiem burtiem) vai par lielo burtu (kad seko kamieļu lielajiem burtiem).
- Masīvs tiek pārbaudīts, vai nav atstarpes, un burts tūlīt aiz atstarpes tiek pārveidots par lielo burtu.
- Ja tiek atrasta rakstzīme, kas nav atstarpe, tā tiek kopēta iegūtajā masīvā.
Realizēsim algoritmu Java programmā.
