Java JDK 18.0.2 (64-bit)

Java JDK 18.0.2 (64-bit)
Java Development Kit 64 位(也稱為 JDK)包含編譯,調試和運行使用 Java 編程語言編寫的小應用程序和應用程序所需的軟件和工具。 JDK 的主要組件是一組編程工具,包括 javac,jar 和 archiver,它們把相關的類庫打包成一個 JAR 文件。這個工具還有助於管理 JAR 文件,javadoc - 文檔生成器,它自動從源代碼註釋生成文檔,jdb - 調試器,jps - 進程狀態工具,顯示當前 Java 進程的進程信息,javap - 類文件反彙編程序,以及其他很多組件。

JDK 64 位還附帶了一個完整的 Java 運行時環境,通常稱為私有運行時。它由 Java 虛擬機和生產環境中存在的所有類庫以及僅對開發人員有用的附加庫(例如國際化庫和 IDL 庫)組成。下載 Java 開發工具包離線安裝程序安裝 64bit for Windows

JDK 內容:

開發工具
(在 bin / 子目錄中)將幫助您開發,執行,調試和編寫用 JavaTM 編程語言編寫的程序的工具和實用程序。

Runtime Environment
(在 jre / 子目錄中)供 JDK 使用的 Java 運行時環境(JRE)的實現。 JRE 包括一個 Java 虛擬機(JVM),類庫和其他支持執行用 Java 編程語言編寫的程序的文件.

附加庫
(在 lib / 子目錄中)開發工具需要的附加類庫和支持文件.

Demo 小應用程序和應用程序
(在演示 / 子目錄中)Java 平台編程的示例,包括源代碼。這些包括使用 Swing 和其他 Java 基礎類的示例,以及 Java 平台調試器體系結構.

示例代碼
(在示例子目錄中)帶有源代碼的樣本,用於某些 Java API 的編程。

C 頭文件
(在 include / 子目錄中)支持使用 Java 本地接口,JVM 工具接口和 Java 平台的其他功能進行本地代碼編程的頭文件。下載 Java 開發工具包離線安裝程序安裝程序 64bit for Windows

源代碼
(在 src.zip 中)構成 Java 核心 API 的所有類的 Java 編程語言源文件(即 java。*,javax。* 和某些 org 的源文件。* 包,但不包括 com.sun。* 包)。此源代碼僅供參考,旨在幫助開發人員學習和使用 Java 編程語言。這些文件不包括平台特定的實現代碼,不能用於重建類庫。要提取這些文件,請使用任何常用的 zip 實用程序。或者,您可以在 JDK 的 bin / 目錄中使用 Jar 實用程序:jar xvf src.zip.

更新日誌

What's new in this version:

Removed Features and Options:
Security-libs/javax.security:
- Remove the Alternate ThreadLocal Implementation of the Subject::current and Subject::callAs APIs
- The “jdk.security.auth.subject.useTL” system property and the alternate ThreadLocal implementation of the Subject::current and Subject::callAs APIs have been removed. The default implementation of these APIs is still supported.
- See JDK-8282676 (not public)

Other Notes:
Hotspot/runtime:
CPU Shares Ignored When Computing Active Processor Count:
- Previous JDK releases used an incorrect interpretation of the Linux cgroups parameter "cpu.shares". This might cause the JVM to use fewer CPUs than available, leading to an under utilization of CPU resources when the JVM is used inside a container.
- Starting from this JDK release, by default, the JVM no longer considers "cpu.shares" when deciding the number of threads to be used by the various thread pools. The -XX:+UseContainerCpuShares command-line option can be used to revert to the previous behavior. This option is deprecated and may be removed in a future JDK release.
- See JDK-8281181

Tools/javac:
Lambda Deserialization Fails for Object Method References on Interfaces:
- Deserialization of serialized method references to Object methods, which was using an interface as the type on which the method is invoked, can now be deserialized again. Note the classfiles need to be recompiled to allow the deserialization.
- See JDK-8282080

Bug Fixes:
- This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update
