System Requirements

The Java Development Kit (JDK) is an implementation of either one of the Java Platform, Standard Edition, Java Platform, Enterprise Edition, or Java Platform, Micro Edition platforms released by Oracle Corporation in the form of a binary product aimed at Java developers on Solaris, Linux, macOS or Windows.The JDK includes a private JVM and a few other resources to finish the development of a.

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.

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

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.

Click Continue.
The Installation Type window appears.
Click Install.
A window appears that says 'Installer is trying to install new software. Type your password to allow this.'
Enter the Administrator login and password and click Install Software.
The software is installed and a confirmation window appears.
Refer to http://www.oracle.com/technetwork/java/javase/downloads/jdk-for-mac-readme-1564562.html for more information about the installation.
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

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

For example, to uninstall 8u6:

Mac For Java Development Kit For Beginners

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.

Open source and cross-platform development toolkit designed by Oracle for building multi-platform Java based applications and applets

Oracle’s JDK (short for Java Development Kit) comes with a built-in comprehensive collection of tools that make it simple to develop and test programs, applications and components written using the Java programming language and designed to run on the Java platform.

Wide variety of powerful Java development tools

Moreover, the JDK comes bundled with a collection of utilities and tools that help developers to create, debug, execute, and effortlessly design documentation for their Java programming language based programs.

Jdk For Mac

You can find a detailed list of all included tools in the 'JDK Tools and Utilities' section on Oracle's documentation website.

Inbuilt JRE distribution and Apache Derby relational database

In addition, the JDK package also features a Java Runtime Environment (JRE) implementation, including a Java Virtual Machine (JVM), various class libraries, and a number of other files created to support the execution of Java software.

Also, JDK comes packed with Oracle's Java DB, a specially prepared distribution of the Apache Derby relational database. Java DB is based on SQL and the Java programming language and it includes Derby without any sort of modification to Derby's underlying source code (further details can be found on the Java DB documentation page).

Comprehensive Java programming language source file collection

On top of that, the JDK contains a collection of C header files that offer native-code programming support with the help of the JVM Tool Interface, Java's Native Interface, and a host of other functionality features of the Java platform.

The JDK also provides access to the Java programming language source files for all the classes contained within the Java core API (sources files for the java.*, javax.* and some org.* packages, but not for the com.sun.* packages).
