Bu \u00f6zelli\u011fi, Java’y\u0131 kurumsal uygulamalardan mobil geli\u015ftirmeye (Android), web uygulamalar\u0131ndan b\u00fcy\u00fck veri i\u015fleme platformlar\u0131na kadar geni\u015f bir yelpazede pop\u00fcler bir se\u00e7im haline getirmi\u015ftir.<\/p>\n

Ubuntu 20.04 LTS (Long Term Support) s\u00fcr\u00fcm\u00fc, kararl\u0131l\u0131\u011f\u0131, g\u00fcvenilirli\u011fi ve uzun s\u00fcreli g\u00fcvenlik g\u00fcncellemeleri nedeniyle sunucular ve geli\u015ftirme ortamlar\u0131 i\u00e7in s\u0131k\u00e7a tercih edilen bir Linux da\u011f\u0131t\u0131m\u0131d\u0131r. apt<\/code> (Advanced Package Tool) ise Ubuntu ve Debian tabanl\u0131 di\u011fer da\u011f\u0131t\u0131mlarda yaz\u0131l\u0131m paketlerini y\u00f6netmek i\u00e7in kullan\u0131lan g\u00fc\u00e7l\u00fc bir komut sat\u0131r\u0131 arac\u0131d\u0131r. apt<\/code> sayesinde Java kurulumu, ba\u011f\u0131ml\u0131l\u0131klar\u0131n otomatik olarak \u00e7\u00f6z\u00fclmesi ve sistemle uyumlu bir \u015fekilde entegre edilmesi a\u00e7\u0131s\u0131ndan son derece kolay ve g\u00fcvenilirdir.<\/p>\n

Bu makalede, Ubuntu 20.04 \u00fczerinde Java’n\u0131n farkl\u0131 s\u00fcr\u00fcmlerini apt<\/code> paket y\u00f6neticisi arac\u0131l\u0131\u011f\u0131yla nas\u0131l kuraca\u011f\u0131n\u0131z\u0131, y\u00f6netece\u011finizi ve bir geli\u015ftirme ortam\u0131 i\u00e7in nas\u0131l yap\u0131land\u0131raca\u011f\u0131n\u0131z\u0131 ayr\u0131nt\u0131l\u0131 olarak ele alaca\u011f\u0131z.

Java Versiyonlar\u0131 ve Tercihler<\/h2>\n

Java ekosistemi, zaman i\u00e7inde \u00e7e\u015fitli s\u00fcr\u00fcmler ve uygulamalarla geni\u015flemi\u015ftir. \u00d6zellikle OpenJDK ve Oracle JDK aras\u0131ndaki farklar ve LTS (Long Term Support) s\u00fcr\u00fcmlerinin \u00f6nemi, kurulum \u00f6ncesinde anla\u015f\u0131lmas\u0131 gereken kritik noktalard\u0131r.<\/p>\n

OpenJDK ve Oracle JDK Aras\u0131ndaki Farklar<\/h3>\n

Java’n\u0131n iki ana uygulamas\u0131 OpenJDK ve Oracle JDK’d\u0131r. Temel olarak ayn\u0131 kodu payla\u015fsalar da, aralar\u0131nda baz\u0131 \u00f6nemli farklar bulunmaktad\u0131r:<\/p>\n

* OpenJDK (Open Java Development Kit):<\/strong> A\u00e7\u0131k kaynakl\u0131 ve \u00fccretsiz bir Java platformu uygulamas\u0131d\u0131r. Oracle ve di\u011fer bir\u00e7ok \u015firket ve birey taraf\u0131ndan aktif olarak geli\u015ftirilmektedir. \u00c7o\u011fu Linux da\u011f\u0131t\u0131m\u0131, varsay\u0131lan Java paketi olarak OpenJDK’y\u0131 sunar. Geli\u015ftirme ve \u00fcretim ortamlar\u0131nda kullan\u0131m\u0131 tamamen \u00fccretsiz ve lisans sorunlar\u0131ndan ar\u0131nd\u0131r\u0131lm\u0131\u015ft\u0131r. Genellikle en son \u00f6zellikler ve g\u00fcvenlik g\u00fcncellemeleri OpenJDK projesi \u00fczerinden yay\u0131nlan\u0131r.
\n* Oracle JDK:<\/strong> Oracle taraf\u0131ndan da\u011f\u0131t\u0131lan ticari bir Java uygulamas\u0131d\u0131r. Ge\u00e7mi\u015fte \u00fccretsiz olsa da, Oracle Java 11 ve sonraki s\u00fcr\u00fcmlerden itibaren ticari kullan\u0131m i\u00e7in \u00fccretli bir lisans gerektirmektedir. Geli\u015ftirme amac\u0131yla kullan\u0131labilirken, \u00fcretim ortamlar\u0131nda veya ticari uygulamalarda belirli lisans ko\u015fullar\u0131na tabidir. Oracle JDK, OpenJDK’ya g\u00f6re baz\u0131 ek tescilli ara\u00e7lar veya performans iyile\u015ftirmeleri i\u00e7erebilir, ancak \u00e7o\u011fu durumda bu farkl\u0131l\u0131klar ortalama bir kullan\u0131c\u0131 veya geli\u015ftirici i\u00e7in belirleyici de\u011fildir.<\/p>\n

G\u00fcn\u00fcm\u00fczde, lisanslama karma\u015f\u0131kl\u0131\u011f\u0131 ve OpenJDK’n\u0131n olgunlu\u011fu ve topluluk deste\u011fi g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, \u00e7o\u011fu geli\u015ftirici ve kurulu\u015f i\u00e7in OpenJDK tercih edilen se\u00e7enektir. Ubuntu’nun resmi depolar\u0131nda bulunan t\u00fcm Java paketleri OpenJDK tabanl\u0131d\u0131r.<\/p>\n

LTS S\u00fcr\u00fcmlerinin \u00d6nemi<\/h3>\n

Java’n\u0131n belirli s\u00fcr\u00fcmleri “LTS” (Long Term Support – Uzun S\u00fcreli Destek) olarak i\u015faretlenir. Bu s\u00fcr\u00fcmler, Oracle ve OpenJDK toplulu\u011fu taraf\u0131ndan daha uzun s\u00fcre g\u00fcvenlik g\u00fcncellemeleri ve hata d\u00fczeltmeleri al\u0131r. LTS olmayan s\u00fcr\u00fcmler genellikle alt\u0131 ayda bir yay\u0131nlan\u0131r ve daha k\u0131sa bir destek d\u00f6ng\u00fcs\u00fcne sahiptir.<\/p>\n

Pop\u00fcler LTS Java s\u00fcr\u00fcmleri \u015funlard\u0131r:<\/p>\n

* Java 8 (LTS):<\/strong> Hala bir\u00e7ok eski kurumsal uygulamada kullan\u0131lmaktad\u0131r. Uzun s\u00fcreli deste\u011fi sayesinde g\u00fcvenilirli\u011fini korumu\u015ftur.
\n* Java 11 (LTS):<\/strong> Java 8’den sonraki ilk b\u00fcy\u00fck LTS s\u00fcr\u00fcm\u00fcd\u00fcr. Mod\u00fclerlik (Jigsaw projesi) gibi \u00f6nemli iyile\u015ftirmeler getirmi\u015ftir. Bir\u00e7ok yeni projenin ve geli\u015ftiricinin tercihidir.
\n* Java 17 (LTS):<\/strong> Java 11’den sonraki bir di\u011fer \u00f6nemli LTS s\u00fcr\u00fcm\u00fcd\u00fcr. Sealed Classes, Pattern Matching gibi yeni dil \u00f6zelliklerini ve performans iyile\u015ftirmelerini i\u00e7erir. Modern uygulamalar i\u00e7in g\u00fc\u00e7l\u00fc bir adayd\u0131r.
\n* Java 21 (LTS):<\/strong> En yeni LTS s\u00fcr\u00fcm\u00fcd\u00fcr. Sanal Thread’ler (Project Loom), Sequenced Collections gibi \u00f6nemli yenilikler sunar.<\/p>\n

Hangi s\u00fcr\u00fcm\u00fc se\u00e7ece\u011finiz, projenizin gereksinimlerine, kullanaca\u011f\u0131n\u0131z k\u00fct\u00fcphanelerin uyumlulu\u011funa ve kurulu\u015funuzun standartlar\u0131na ba\u011fl\u0131d\u0131r. Yeni bir proje ba\u015flat\u0131yorsan\u0131z, genellikle en son LTS s\u00fcr\u00fcm\u00fc (\u015fu an i\u00e7in Java 21 veya 17) tercih etmek iyi bir ba\u015flang\u0131\u00e7 noktas\u0131d\u0131r.<\/p>\n

Sistem Gereksinimleri ve Haz\u0131rl\u0131k<\/h2>\n

Java kurulumuna ba\u015flamadan \u00f6nce sisteminizin belirli gereksinimleri kar\u015f\u0131lad\u0131\u011f\u0131ndan ve temel haz\u0131rl\u0131k ad\u0131mlar\u0131n\u0131n tamamland\u0131\u011f\u0131ndan emin olman\u0131z gerekir.<\/p>\n

Gerekli \u00d6nko\u015fullar<\/h3>\n

* Ubuntu 20.04 LTS:<\/strong> Bu k\u0131lavuz, \u00f6zellikle Ubuntu 20.04 (Focal Fossa) s\u00fcr\u00fcm\u00fc i\u00e7in yaz\u0131lm\u0131\u015ft\u0131r. Di\u011fer Ubuntu veya Debian tabanl\u0131 da\u011f\u0131t\u0131mlarda da benzer ad\u0131mlar izlenebilir, ancak paket adlar\u0131 veya versiyonlar\u0131 farkl\u0131l\u0131k g\u00f6sterebilir.
\n* sudo<\/code> Yetkilerine Sahip Bir Kullan\u0131c\u0131:<\/strong> Java paketlerini kurmak ve sistem \u00e7ap\u0131nda de\u011fi\u015fiklikler yapmak i\u00e7in y\u00f6netici (root) ayr\u0131cal\u0131klar\u0131na ihtiyac\u0131n\u0131z olacakt\u0131r. Bu nedenle, sudo<\/code> komutunu kullanabilen bir kullan\u0131c\u0131 hesab\u0131yla oturum a\u00e7m\u0131\u015f olman\u0131z gerekmektedir.

Paket Listesini G\u00fcncelleme<\/h3>\n

Kuruluma ba\u015flamadan \u00f6nce, sisteminizin paket listesini g\u00fcncellemek ve mevcut paketleri y\u00fckseltmek iyi bir uygulamad\u0131r. Bu, en son paket bilgilerini alman\u0131z\u0131 sa\u011flar ve olas\u0131 ba\u011f\u0131ml\u0131l\u0131k sorunlar\u0131n\u0131 \u00f6nler.<\/p>\n

JRE, Java uygulamalar\u0131n\u0131 \u00e7al\u0131\u015ft\u0131rmak i\u00e7in gerekli olan JVM ve temel k\u00fct\u00fcphaneleri i\u00e7erir.<\/p>\n

Oracle JDK Kurulumu (\u0130ste\u011fe Ba\u011fl\u0131)<\/h2>\n
Oracle JDK, ticari lisanslama ko\u015fullar\u0131 nedeniyle OpenJDK’ya g\u00f6re daha az tercih edilse de, baz\u0131 \u00f6zel durumlar veya eski projeler i\u00e7in hala gerekli olabilir. Oracle JDK’y\u0131 Ubuntu’ya kurman\u0131n iki ana yolu vard\u0131r: manuel kurulum veya PPA (Personal Package Archive) kullanarak kurulum. Oracle’\u0131n lisans politikalar\u0131n\u0131n s\u0131k s\u0131k de\u011fi\u015fti\u011fini ve bu nedenle PPA’lar\u0131n g\u00fcvenilirli\u011finin zaman zaman sorunlu olabilece\u011fini unutmamak \u00f6nemlidir.<\/p>\n
