Java 14 \u00d6zellikleri: Modern Java Geli\u015ftirme \u0130\u00e7in Yenilikler<\/h2>\n

Switch \u0130fadeleri (Standard)<\/h2>\n

Java 12 ve Java 13’te \u00f6nizleme \u00f6zelli\u011fi olarak sunulan switch<\/code> ifadeleri, Java 14 ile standart bir \u00f6zellik haline gelmi\u015ftir (JEP 361). Geleneksel switch<\/code> deyimi, break<\/code> anahtar kelimesinin unutulmas\u0131yla ortaya \u00e7\u0131kabilen “fall-through” hatalar\u0131 ve okunabilirli\u011fi d\u00fc\u015f\u00fcren yap\u0131s\u0131yla ele\u015ftirilmekteydi. switch<\/code> ifadeleri, bu sorunlar\u0131 ortadan kald\u0131rarak daha k\u0131sa, daha g\u00fcvenli ve daha esnek bir yap\u0131 sunar.<\/p>\n

Geleneksel switch<\/code> deyimi bir ifade (statement) iken, yeni switch<\/code> yap\u0131s\u0131 bir ifade (expression) olarak kullan\u0131labilir, yani bir de\u011fer d\u00f6nd\u00fcrebilir. Bu, kodu \u00f6nemli \u00f6l\u00e7\u00fcde basitle\u015ftirir. Yeni s\u00f6zdiziminde, case<\/code> etiketleri -><\/code> (ok) operat\u00f6r\u00fc ile birle\u015ftirilir ve her case<\/code> blo\u011fu tek bir ifade, bir kod blo\u011fu veya bir throw<\/code> ifadesi i\u00e7erebilir.<\/p>\n

Yukar\u0131daki \u00f6rnekte g\u00f6r\u00fcld\u00fc\u011f\u00fc gibi, yeni switch<\/code> ifadesi \u00e7ok daha kompakt ve okunabilir bir yap\u0131 sunar. break<\/code> kullanma zorunlulu\u011fu ortadan kalkt\u0131\u011f\u0131 i\u00e7in fall-through hatalar\u0131 da engellenmi\u015f olur.

Bu, karma\u015f\u0131k hesaplamalar\u0131n veya birden fazla ifadenin bir case<\/code> blo\u011funda yer almas\u0131 gerekti\u011finde faydal\u0131d\u0131r.<\/p>\n

Java Flight Recorder (JFR), Java uygulamalar\u0131n\u0131n ve JVM’nin \u00e7al\u0131\u015fma zaman\u0131 davran\u0131\u015f\u0131n\u0131 izlemek ve sorun gidermek i\u00e7in g\u00fc\u00e7l\u00fc bir ara\u00e7t\u0131r. Geleneksel olarak, JFR verileri bir dosyaya kaydedilir ve daha sonra analiz edilirdi. Java 14 ile sunulan “JFR Event Streaming” (JEP 349), JFR olaylar\u0131n\u0131n canl\u0131 olarak bir API arac\u0131l\u0131\u011f\u0131yla t\u00fcketilmesine olanak tan\u0131r.<\/p>\n
Bu \u00f6zellik, uygulama \u00e7al\u0131\u015f\u0131rken performans verilerini, sistem olaylar\u0131n\u0131 ve di\u011fer JVM metriklerini ger\u00e7ek zamanl\u0131 olarak izlemek isteyen geli\u015ftiriciler ve operasyon ekipleri i\u00e7in b\u00fcy\u00fck bir avantajd\u0131r. Art\u0131k JFR verilerini s\u00fcrekli olarak bir dosyaya yaz\u0131p okumaya gerek kalmadan, do\u011frudan bellek i\u00e7i ak\u0131\u015flardan i\u015flenebilir.<\/p>\n
JFR Event Streaming’in faydalar\u0131:<\/p>\n
*   Ger\u00e7ek Zamanl\u0131 \u0130zleme<\/strong>: Uygulama davran\u0131\u015f\u0131n\u0131 an\u0131nda g\u00f6zlemleme, performans sorunlar\u0131n\u0131 h\u0131zla tespit etme.
\n*   Dinamik Analiz<\/strong>: Uygulaman\u0131n performans\u0131na ve kaynak kullan\u0131m\u0131na dinamik olarak yan\u0131t veren ara\u00e7lar geli\u015ftirme.
\n*   Otomasyon<\/strong>: JFR verilerini otomatik sistemlere entegre ederek uyar\u0131lar olu\u015fturma veya otomatik eylemler tetikleme.
\n*   Daha Az Disk I\/O<\/strong>: Verileri do\u011frudan ak\u0131\u015ftan okuyarak disk yazma y\u00fck\u00fcn\u00fc azaltma.<\/p>\n
Bu API, jdk.jfr.consumer<\/code> paketi alt\u0131nda bulunur ve geli\u015ftiricilerin kendi \u00f6zel JFR t\u00fcketicilerini yazmalar\u0131na olanak tan\u0131r.<\/p>\n

Non-Volatile Mapped Byte Buffers (JEP 352)<\/h3>\n
Bu JEP, MappedByteBuffer<\/code> i\u00e7in yeni bir mod olan MAP_SYNC<\/code>‘yi tan\u0131t\u0131r.

Kal\u0131c\u0131 bellek, g\u00fc\u00e7 kesintilerinde bile verilerini koruyabilen yeni bir depolama teknolojisidir.
