JDK Installation

Mac OS X Port Project. The goal of this Project is to produce a high-quality, open source version of JDK 7 for the Mac. The final release has the following goals: Pass all appropriate certification tests for Java SE 7; Include a complete, native Cocoa-based UI Toolkit; Provide excellent performance; This Project is sponsored by the Porters.

The JDK installation file can be obtained from the Oracle website withdownload page:
http://www.oracle.com/technetwork/java/javase/downloads (look for Java SE version 8)
The installation is simple: open the .dmg installationfile and click on the .pkg file within.Verify the installation by opening the Terminalfrom the System Utilities, and at the terminal prompt type:to verify that the correct JDK version is in use.

Netbeans Installation

NetBeans is Oracle's community-based Integrated Development Environment (IDE) for a variety of software development interests including Java, Php, C/C++, etc.It requires a JDK installation. The home and download pages are these:
http://netbeans.org
http://netbeans.org/downloads/8.2 (to get version 8.2)

The download link on the home page currently points to Apache/NetBeans, version 10.0.

The download I prefer is: Download jdk 8 mac os x64

Forcing NetBeans to use JDK1.8

NetBeans on MAC OS X uses a version of JDK in some non-explicit way,and it's not always what you want. Usually it's based onthe the most recent JDK installation.So if you installed JDK 11, NetBean8.2 will not work withoutmaking the configuation file edit suggested in this site:Open a terminal shell and execute this command:You'll get a listing of all installed JDKs; look for JDK 8 installations ('Java SE 8'). If you don't have one,then download a JDK 8 version and install it. EachJDK versionshould have an associated JDK home directory, which we'll assume the one corresponding to jdk1.8.0_8u202:Then edit the following file (using nano):Scroll down the file, looking for the line:Replace it by the following line, substituting the home directory you saw above (get the version right):Exit nano, saving the changes and start NetBeans8.2. It should work!

Personalize NetBeans

I recommend spending some time personalizing NetBeans' settings.

Author and License

NetBeans automatically adds some level of documentation to Java (and other types of) filesit generates; in particular Licensing and Author information.The licensing information is not particularly revelant to our needs,but setting the user name is important.
  1. Set the user name which will be generated automatically in every class file.Go to Tools ⇾ Templates ⇾ Settings.Edit the file, setting the 'user' variable.
  2. Next, get rid of the Licensing information.Go to Tools ⇾ Templates ⇾ Licenses.Save the current 'Default License' by clicking on it andselecting Duplicate, thereby creating a copy Here is the current content of the license file:
    Default License
    DO NOT DELETE THIS FILE!Simply select the content and delete it, or replace itby something more meaningful to you.

Source formatting

NetBeans has a very useful feature called source formattingaccessible via Source ⇾ Format. By default, it willformat the entire file. If a region is selected, it will formatthe region only. It is a good idea set these the way you like.
  1. Select Tools ⇾ Options, or on the MAC: Edit ⇾ Preferences.
  2. Choose Editor and then the Formatting tab.
  3. From the Language selection, choose All Languages(we're only using Java, but these settings are useful across the board).Leave the 'Expand Tabs to Spaces' checked and set these:
  4. From the Language selection, choose JavaSet this:
  5. Choose the Alignment category.In the New Lines section, check the checkboxes for these:
    'else'
    'while'
    'catch'
    'finally'

Hello World Program

NetBeans creates directories called src which consist ofone or more package of Java source files along with other typesof support files. The compiled classes are kept in a separate build directory.To create a simple 'Hello World' program, start upNetBeans and follow the steps below.
  1. Select File ⇾ New Project
  2. In the New Project window, select the Java category,and choose Java Application, then Next.
  3. Choose the project name HelloWorld.The other settings have default values which you probably want to use.The project location cannot be an existing directory. NetBeans also pre-checks the box Create Main Class.Leave it checked. Click Finish.
  4. In the left-hand window there you can observe three views ofthe netbeans contents: Projects, Files, Services. For the most part you can work from the Projects view. In the Projects window you willsee the file HelloWorld.java as part of the automatically-created helloworld package.

  5. Go to the Files view and observe the structure which NetBeans creates. The src folder ismeant to hold all the source packages.The HelloWorld.java file is in a package directory HelloWorld within the src folder.

  6. Within the public static void main function, typeObserve the various syntactic assists which the editor offerswhen you pause after typing a '.'.
  7. Select File ⇾ Save (or Ctrl-S) to save.

  8. There are several ways to compile and run this application.One way is to right-click on HelloWorld.java and select Run FileAirport utility mac el capitan download. fromthe popup menu. Look forthe output in the Output window at the bottom.

  9. Another way to build and run the project is by selecting Run ⇾ Cean and Build Projector Shift+F11. This operation goes a step further and archives the compiledclasses into the jar file HelloWorld.jar found in the newly created dist directory.Afterwards, select Run ⇾ Run Project or F6, or the button.

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

This page has these topics:

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.

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

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/star-wars-battlefront-mac-download-demo.html. 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:

Jdk 1.8 Download

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

Uninstalling the JDK

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

Jdk For Mac Os Download

For example, to uninstall 8u6:

Download Java 8 Mac Os X

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.
