Java za poimenovanje razredov, vmesnikov, metod in spremenljivk sledi sintaksi kamelje male črke. Če je ime združeno z dvema besedama, se bo druga beseda vedno začela z veliko črko, na primer maxMarks(), lastName, ClassTest, pri čemer bodo odstranjeni vsi presledki.
Zadevo Camel lahko uporabljate na dva načina:
- Male velike črke, kjer je prvi znak prve besede z malimi črkami. Ta konvencija se običajno upošteva pri poimenovanju metod in spremenljivk. Primer, FirstName, LastName, actionEvent, printArray() itd.
- Velike črke, znane tudi kot naslovne začetnice, kjer je prvi znak prve besede napisan z velikimi črkami. Ta konvencija se običajno upošteva pri poimenovanju razredov in vmesnikov. Na primer Employee, Printable itd.
Pretvarjanje navadne vrvice v kamelo črto
Niz je mogoče pretvoriti v male ali velike navadne črke samo tako, da iz niza odstranite presledke.
Primer malih črk Camel:
Vnos: JavaTpoint je najboljše spletno mesto z vadnicami za programske jezike.
Izhod: javaTpointIsTheBestTutorialSiteForProgrammingLanguages.
Primer velikih črk Camel:
Vnos: to je vadnica za java
Izhod: To je vadnica za Java
Algoritem:
- Prečkajte niz znakov znak za znakom, dokler ne doseže konca.
- Prva črka niza pri indeksu = 0 se pretvori v male črke (če sledi malim črkam) ali v velike črke (če sledi velikim črkam).
- V matriki se preverijo presledki in črka, ki sledi presledku, se pretvori v velike črke.
- Če naletite na znak, ki ni presledek, se kopira v nastalo matriko.
Implementirajmo algoritem v program Java.
