An warware: raba ta sabon layi

Yin aiki tare da igiyoyi a Java fasaha ce ta asali cewa kowane mai shirye-shirye yakamata ya kware sosai. Zai iya zama da wahala musamman lokacin ฦ™oฦ™arin karya igiya zuwa layi daban-daban; Ana kiran wannan tsari a matsayin 'Raba ta Sabon Layi'. A cikin wannan labarin, za mu samar da jagora mai sauฦ™i don bi kan yadda ake samun nasara da raba kirtani ta sabon layi a Java.

Fahimtar tsarin na tsaga igiya yana da mahimmanci don sarrafa bayanai da kuma fitar da bayanai. Anan, za mu nutse cikin zurfin tunani da hanyoyin da za a iya cimmawa don cimma sakamako cikin sauฦ™i da inganci.

Fahimtar Ayyukan Rarraba a Java

A cikin Java, aikin raba hanya hanya ce mai amfani ta Ajin kirtani kuma ana amfani da shi don raba kirtani zuwa tsararrun ฦ™ananan igiyoyi dangane da ฦ™ayyadadden ฦ™ayyadaddun iyaka ko magana na yau da kullun.

String str = "HellonWorld";
String[] lines = str.split("n");
for(String line: lines){
    System.out.println(line);
}

A cikin lambar da ke sama, n shine sabon layi yana gaya wa tsarin ya karya layin kuma ya bi sauran kirtani a matsayin sabon layi. Hanyar raba sa'an nan ya haifar da tsararrun ฦ™ananan igiyoyi ta hanyar karya zaren duk lokacin da ya ci karo da mai iyaka (a wannan yanayin, 'n'). Ga kowane madauki daga baya yana fitar da kowane layi akan layinsa.

Yin aiki tare da ษ—akunan karatu na Java

Daidaitaccen ษ—akin karatu na Java yana bayarwa darussa da hanyoyin da yawa don taimaka mana sarrafa igiyoyi. Baya ga ajin String da aka ambata a baya, sauran azuzuwan sun haษ—a da Class Scanner da BufferedReader class.

// Using Scanner class
Scanner scanner = new Scanner(str);
while (scanner.hasNextLine()) {
  String line = scanner.nextLine();
  System.out.println(line);
}

// Using BufferedReader class
BufferedReader reader = new BufferedReader(new StringReader(str));
String line;
while ((line = reader.readLine()) != null) {
  System.out.println(line);
}

Na'urar daukar hotan takardu tana amfani da mai iyakancewa don karya shigarwar zuwa alamu. Ta hanyar tsoho, yana amfani da sararin samaniya. Ana amfani da hanyoyin hasNextLine da hanyoyin layi na gaba don karanta kowane layi. Hakazalika, hanyar karanta layin BufferedReader yana karanta layin rubutu. Ana ษ—aukar layin da za a ฦ™are ta hanyar ciyarwar layi ('n'), komawar karusa ('r'), ko dawowar karusa ta hanyar ciyarwar layi nan da nan.

Fahimtar Manipulation String a Java

Manipulation igiya kayan aiki ne mai ฦ™arfi a Java kuma yana da mahimmanci don sarrafa bayanai masu inganci. Hanyoyin da za a iya amfani da waษ—annan hanyoyin suna da yawa kamar cire karin farin sarari, maye gurbin wasu haruffa ko kalmomi, canza harka, da tsaga kirtani. Yana da mahimmanci a lura cewa igiyoyi a Java ba su canzawa - da zarar an ฦ™irฦ™ira su, ba za a iya canza su ba. Duk wani aiki da ke da alama yana canza kirtani yana haifar da sabo.

Wannan labarin yana nufin samar da a m fahimta na tsagawar kirtani ta sabon fasalin layi a cikin shirye-shiryen Java, nutsewa cikin sarrafa kirtani da ษ—akunan karatu na Java masu amfani. Samun sanin waษ—annan kayan aikin tabbas zai haษ“aka ฦ™warewar coding ษ—in ku da buษ—e sabbin damar yin amfani da bayanai.

Ka tuna, aiwatarwa shine mabuษ—in idan ya zo ga coding. Yi ฦ™oฦ™arin aiwatar da waษ—annan hanyoyin a cikin ฦ™alubalen ฦ™ididdigewa na yau da kullun don samun tsayin daka a kansu.
