JavaOS is predominantly a U/SIM-Card operating system based on a Java virtual machine and running applications on behalf of Operators and Security-Services. It was originally developed by Sun Microsystems.[1] Unlike Windows, Mac OS, Unix, or Unix-like systems which are primarily written in the C programming language, JavaOS is primarily written in Java. It is now considered a legacy system.[2]

As for the Java Update for Mac OS X 10.4, Release 8, Apple says the new software ”delivers improvements to the security and compatibility of Java on Mac OS X 10.4.11 and later.”. Sun Java Runtime Environment 8 For Mac 官方中文版 8.0u162下载是最新JAVA运行库,建立一个运行JAVA的环境.

History[edit]

The Java programming language was introduced by Sun in May 1995. Across the following six months, the Java platform and its ideas propagated through the world. Jim Mitchell and Peter Madany at JavaSoft designed a new operating system, codenamed Kona, written completely in Java. In March 1996, Tom Saulpaugh joined the now seven-person Kona team to design an I/O architecture, having come from Apple as Mac OS engineer since June 1985 and co-architect of Copland.[3]:XI-XIII

JavaOS was first evangelized in a Byte article.[4] In 1996, JavaSoft's official product announcement described the compact OS designed to run 'in anything from net computers to pagers'.[1] In early 1997, JavaSoft transferred JavaOS to SunSoft. In late 1997, Bob Rodriguez led the team to collaborate with IBM who then marketed the platform, accelerated development, and made significant key architectural contributions to the next release of JavaOS, eventually renamed JavaOS for Business.[3]:XI-XIII[5] IBM indicated its focus was more on network computer thin clients, specifically to replace traditional 'green screen' and UNIX terminals, and to implement single application clients.[6] The Chorus distributed real-time operating system was purchased for its microkernel technology.[3]:XIII

JavaSoft has granted licenses to more than 25 manufacturers, including Oracle Corp, Acer Inc., Xerox, Toshiba Corp, and Nokia. IBM and Sun announced the cooperation for JavaOS for Business at the end of March 1998.[2]

In 1999, Sun and IBM announced the discontinuation of the JavaOS product.[7] As early as 2003, Sun materials referred to JavaOS as a 'legacy technology', recommending migration to Java ME, leaving the choice of specific OS and Java environment to the implementer.[citation needed]

Overview[edit]

JavaOS is based on a hardware architecture native microkernel, running on platforms including ARM, PowerPC, SPARC, StrongARM, and IA-32 (x86). The Java virtual machine runs on top of the microkernel. All device drivers are written in Java and executed by the virtual machine. A graphics and windowing system implementing the AWTAPI is also written in Java.[3][page needed]

JavaOS was designed to run on embedded systems and has applications in devices such as set-top boxes, networking infrastructure, and ATMs. It comes with the JavaStation.[citation needed]

This page describes how to install and uninstall JDK 8 for OS X computers.

This page has these topics:

Sun Java For Mac Os 10.10

See 'JDK 8 and JRE 8 Installation Start Here' for general information about installing JDK 8 and JRE 8.

See 'OS X Platform Install FAQ' for general information about installing JDK 8 on OS X.

System Requirements

Observe the following requirements:

  • Any Intel-based computer running OS X 10.8 (Mountain Lion) or later.

  • Administrator privileges.

Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Download Java For Mac Os X

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.

JDK Installation Instructions

When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

  • jdk-8uversion-macosx-amd64.dmg

  • jdk-8uversion-macosx-x64.dmg

Java

Where version is 6 or later.

  1. Download the file.

    Before the file can be downloaded, you must accept the license agreement.

  2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

    A Finder window appears containing an icon of an open box and the name of the .pkg file.

  3. Double click the package icon to launch the Install app.

    The Install app displays the Introduction window.


    Note:

    In some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the Continue button.

  4. Click Continue.

    The Installation Type window appears.

  5. Click Install.

    A window appears that says 'Installer is trying to install new software. Type your password to allow this.'

  6. Enter the Administrator login and password and click Install Software.

    The software is installed and a confirmation window appears.

  7. Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.

  8. After the software is installed, delete the .dmg file if you want to save disk space.

Determining the Default Version of the JDK

If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.

There can be multiple JDKs installed on a system, as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Uninstalling the JDK

Sun Java Mac

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

Sun Java For Mac Os 10.13

For example, to uninstall 8u6:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
