An warware: sau biyu zuwa tsayi

Java harshe ne mai ƙarfi kuma mai sassauƙa, mai daidaitawa ga buƙatu daban-daban kuma ana amfani da shi sosai a cikin duniyar ci gaba. Daga cikin ayyukansa masu yawa, wanda ya fi dacewa shine ikon canza nau'ikan bayanai. Misali na yau da kullun shine jujjuya nau'in bayanai na 'biyu' zuwa nau'in bayanai mai tsayi. Wannan juzu'i na iya amfani da dalilai da yawa; babba, yana ba da damar haɓaka amincin bayanan bayanai, rage damar kurakurai na lissafi, waɗanda suke da alama marasa ƙarfi amma suna iya yin tasiri sosai ga sakamakon aiki. Bayan haka, waɗannan jujjuyawar kuma na iya ba da hanya don dacewa tsakanin tsarin ko kayayyaki daban-daban.

Hanyar Java – Sau biyu zuwa Dogon Juya

Java yana ba da hanyar da aka gina don aiwatar da wannan juyawa; hanyar ita ce madaidaiciya kuma mai sauƙin amfani. Wannan hanyar wani bangare ne na ajin 'java.lang.Double' kuma yana biyan bukatun wannan jujjuya kai tsaye.

double testDouble = 152.65;
long convertedLong = (long) testDouble;
System.out.println(convertedLong);

A cikin misalin da ke sama, muna da ƙima biyu da aka adana a ma'aunin 'testDouble'. Ta hanyar sanya '(dogon)' kawai kafin 'testDouble', Java ta fahimci shi azaman umarni don canza 'testDouble' zuwa nau'in bayanai mai tsawo. Ana adana sakamakon wannan aiki a cikin 'convertedLong', wanda daga baya ya sami bugawa.
