Java SE Development Kit (JDK) 24.0.1 freeware
The Java SE Development Kit (JDK) by Oracle is a comprehensive toolkit essential for Java developers. It includes the Java Runtime Environment (JRE), an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc), and other tools needed for Java development. Renowned for its reliability and performance, the JDK supports robust application development across various platforms, making it a cornerstone for modern software engineering.

| 24.0.1 | Apr 15, 2025 | New Release | Major New Functionality: Language Previews: Primitive Types in Patterns, instanceof, and switch (Second Preview) Enhance pattern matching by allowing primitive types in all pattern contexts, and extend instanceof and switch to work with all primitive types. This is a preview language feature. Flexible Constructor Bodies (Third Preview): In constructors in the Java programming language, allow statements to appear before an explicit constructor invocation, i.e., super(..) or this(..). The statements cannot reference the instance under construction, but they can initialize its fields. Initializing fields before invoking another constructor makes a class more reliable when methods are overridden. This is a preview language feature. Module Import Declarations (Second Preview): Enhance the Java programming language with the ability to succinctly import all of the packages exported by a module. This simplifies the reuse of modular libraries, but does not require the importing code to be in a module itself. This is a preview language feature. Simple Source Files and Instance Main Methods (Fourth Preview): Evolve the Java programming language so that beginners can write their first programs without needing to understand language features designed for large programs. Far from using a separate dialect of the language, beginners can write streamlined declarations for single-class programs and then seamlessly expand their programs to use more advanced features as their skills grow. Experienced developers can likewise enjoy writing small programs succinctly, without the need for constructs intended for programming in the large. This is a preview language feature. Performance and Runtime: Compact Object Headers (Experimental): Reduce the size of object headers in the HotSpot JVM from between 96 and 128 bits down to 64 bits on 64-bit architectures. This will reduce heap size, improve deployment density, and increase data locality. Late Barrier Expansion for G1: Simplify the impleme |

| 23.0.2 | Feb 4, 2025 | New Release | JDK 23.0.2 contains IANA time zone data 2024b which contains the following changes: Improve historical data for Mexico, Mongolia, and Portugal. System V names are now obsolescent. The main data form now uses %z. The code now conforms to RFC 8536 for early timestamps. Support POSIX.1-2024, which removes asctime_r and ctime_r. Other Notes: core-libs/java.lang ➜ ProcessBuilder on Windows Quotes Argument Strings Containing Any Space Character (JDK-8335428 (not public)): On Windows, the ProcessBuilder has expanded the quoting of argument strings when starting a process to ensure they are recognized by the application as a single command argument. The set of space characters has been expanded from space (0x20) to include all space characters as defined by java.lang.Character.isSpaceChar, which includes all Unicode space separator characters, such as EN-SPACE (0x2002), and line separator and paragraph separator characters. core-libs/java.time ➜ Support for Time Zone Database 2024b (JDK-8339637): IANA Time Zone Database has been upgraded to 2024b. This version mainly includes changes to improve historical data for Mexico, Mongolia, and Portugal. It also changes one timestamp abbreviation, for the time zone 'MET'. Also Asia/Choibalsan is now an alias for Asia/Ulaanbaatar. The new tzdata changes also impact some legacy time zone IDs. As per 2024b changes "EST" links to "America/Panama", "HST" links to "Pacific/Honolulu" and "MST" links to "America/Phoenix". To maintain compatibility with the Java SE specification, the java.time.ZoneId.SHORT_IDS Map has not changed. Further details are available at JDK-8342331 Bug Fixes: Target class of upcall stub may be unloaded Extra call to MethodHandle::asType from memory segment var handles fails to inline LambdaForm customization via MethodHandle::updateForm is not thread safe File libCreationTimeHelper.c compile fails on Alpine [REDO] java/nio/file/attribute/BasicFileAttri |
