Java JDK 8 Update 31 (32-bit)

Java JDK 8 Update 31 (32-bit)
Java Development Kit(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,以及其他許多組件。

JDK 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.

JDK 的內容:

開發工具
(在 bin / 子目錄)將幫助您開發,執行,調試和編寫以 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機代碼編程的頭文件.

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。* 和一些 org。* 包的源文件,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.

What's new in this version:

NEW FEATURES AND CHANGES:

SSLv3 is disabled by default:
- Starting with JDK 8u31 release, the SSLv3 protocol (Secure Socket Layer) has been deactivated and is not available by default. See the java.security.Security property jdk.tls.disabledAlgorithms in /lib/security/java.security file.
- If SSLv3 is absolutely required, the protocol can be reactivated by removing "SSLv3" from the jdk.tls.disabledAlgorithms property in the java.security file or by dynamically setting this Security property to "true" before JSSE is initialized.
- It should be noted that SSLv3 is obsolete and should no longer be used.

Changes to Java Control Panel:
- Starting with JDK 8u31 release, SSLv3 protocol is removed from Java Control Panel Advanced options. If the user needs to use SSLv3 for applications, re-enable it manually as follows.
- Enable SSLv3 protocol on JRE level: as described in the previous section.
- Enable SSLv3 protocol on deploy level: edit the deployment.properties file and add the following - deployment.security.SSLv3=true
