Veri Tipleri<\/strong><\/p>\n\n\n\n

Java’da her \u015fey bir nesnedir. Tek istisna veri tipleridir. Java veri tipleri, b\u00fct\u00fcn platformlarda standart b\u00fcy\u00fckl\u00fc\u011fe sahiptir. Bu standart Java’n\u0131n ta\u015f\u0131nabilirli\u011fini sa\u011fl\u0131yor. A\u015fa\u011f\u0131da Java’da bulunan veri tipleri ve b\u00fcy\u00fckl\u00fckleri listelenmi\u015ftir.<\/p>\n\n\n\n

E\u011fer C\/C++ programc\u0131s\u0131 iseniz “unsigned” tipinin olmad\u0131\u011f\u0131 dikkatinizi \u00e7ekmi\u015ftir. Byte tipi ise C\/C++’daki “char” tipinin yerini alm\u0131\u015ft\u0131r. Java’daki char tipi 16 bittir. \u00c7\u00fcnk\u00fc Java karakter verisinde Unicode karakter setini temel al\u0131r.<\/p>\n\n\n\n

Unicode, uluslararas\u0131 karakterleri destekleyen bir standartt\u0131r. Programlar\u0131n\u0131z\u0131n de\u011fi\u015fik platformlarda ve \u00fclkelerde \u00e7al\u0131\u015ft\u0131r\u0131laca\u011f\u0131nda Unicode \u00e7ok uygundur. Yukar\u0131daki tabloda olmayan di\u011fer bir veri tipi ise boolean‘<\/em>d\u0131r. Bir boolean, de\u011fi\u015fken numerik de\u011fere \u00e7evrilemez ve sadece iki de\u011fer alabilir. Bu de\u011ferler “true” ve “false” tur.<\/p>\n\n\n\n

Literaller<\/strong><\/p>\n\n\n\n

Literaller, de\u011fi\u015fkenlere de\u011fer atamak i\u00e7in kullan\u0131l\u0131r. Integer’lara C\/C++ benzer bi\u00e7imde de\u011fer atan\u0131r. 25 gibi tamsay\u0131 atayabilirsiniz. Hexadecimal bir tamsay\u0131 atamak i\u00e7in, say\u0131n\u0131n \u00f6n\u00fcne “0x” ifadesi koyman\u0131z gerekir. \u00d6rne\u011fin, 15 say\u0131s\u0131n\u0131 hexadecimal olarak 0xF \u015feklinde atamal\u0131s\u0131n\u0131z. 8’lik tabanda bir say\u0131 atamak i\u00e7in “0” ifadesini, say\u0131n\u0131n \u00f6n\u00fcne koymal\u0131s\u0131n\u0131z.<\/p>\n\n\n\n

Kayan noktal\u0131 say\u0131lar\u0131 ise direkt 5.2345 \u015feklinde atayabilirsiniz. Bunlar 32 bit float veya 64 bit double olarak saklanabilirler. Belirtmezseniz, varsay\u0131lan 64 bit double’d\u0131r. Belirtmek i\u00e7in yapaca\u011f\u0131n\u0131z tek \u015fey, say\u0131n\u0131n arkas\u0131na float i\u00e7in F, double i\u00e7in D koymakt\u0131r. \u00d6rne\u011fin 5.323 F veya 5.323 D.<\/p>\n\n\n\n

Karakterler, tek t\u0131rnak i\u00e7inde atan\u0131rlar. \u00d6rne\u011fin ‘a’gibi. Escape karakterleri i\u00e7in slash (\\) kullan\u0131l\u0131r. Bunlar da t\u0131rnak i\u00e7inde belirtilir. \\t=tab, \\n=sat\u0131r atlama gibi. Stringler i\u00e7in \u00e7ift t\u0131rnak kullan\u0131l\u0131r. “Maximum Bilgi” gibi. Sat\u0131r atlamas\u0131 yapmak istiyorsan\u0131z “Maximum Bilgi \\n” kullanmal\u0131s\u0131n\u0131z.<\/p>\n\n\n\n

De\u011fi\u015fkenler<\/strong><\/p>\n\n\n\n

Java’da 3 tip de\u011fi\u015fken vard\u0131r: instance, class ve local. Lokal de\u011fi\u015fkenler, metodlar\u0131n ve bloklar\u0131n i\u00e7inde tan\u0131mlanabilirler. Blok, “{” ile ba\u015flayan ve “}” ile biten ifadeler toplulu\u011fudur. Blok i\u00e7inde tan\u0131mlanan lokal de\u011fi\u015fkenler, blok sonuna kadar ge\u00e7erlidir. Genel format\u0131 <tip> <de\u011fi\u015fken ad\u0131> \u015feklindedir. \u00d6rne\u011fin double tipinde pi adl\u0131 de\u011fi\u015fkeni tan\u0131mlayal\u0131m: double pi; bir de\u011fer de atayabilirdik: double pi=3.1415.<\/p>\n\n\n\n

De\u011fi\u015fkenler; harf, say\u0131, dolar i\u015fareti, alt \u00e7izgi ile ba\u015flay\u0131p bu karakterlerle devam edebilir. Ama komutlar, operat\u00f6rler de\u011fi\u015fken ismi olarak kullan\u0131lamazlar.<\/p>\n\n\n\n

A\u00e7\u0131klamalar<\/strong><\/p>\n\n\n\n

Programlar\u0131n\u0131za a\u00e7\u0131klama koymak i\u00e7in, Java’da kullanabilece\u011finiz iki stil vard\u0131r. Birincisi \u00e7ift slash ( \/\/ ). \u00c7ift slash’tan sat\u0131r sonuna kadar olan k\u0131s\u0131mda bulunan her \u015fey a\u00e7\u0131klama olarak kabul edilir.<\/p>\n\n\n\n

\u0130kincisi ise slash ve y\u0131ld\u0131z ( \/*) ile ba\u015flar y\u0131ld\u0131z ve slash ile biter. Bunlar aras\u0131ndaki her \u015fey, a\u00e7\u0131klama olarak kabul edilir. \u00d6rnek 1: double pi; \/\/ pi de\u011fi\u015fkeni double olarak tan\u0131mland\u0131. \u00d6rnek 1: \/* Bu program\u0131n amac\u0131 say\u0131sal loto tahmini yapmakt\u0131r.<\/p>\n\n\n\n
