How To Download Java Development Kit For Mac

The Java Development Kit (JDK), officially named “Java Platform Standard Edition (Java SE)”, is required to write Java programs. Java Runtime (JRE) is required to run Java programs. JRE is included within the JDK along with other tools such as a compiler and debugger. Therefore the first step of writing a Java program, is to install the Java Development Kit. It’s important to always have an up-to-date version of JDK, which can be downloaded here. To jump to the right section for you, choose one of the following links:

Checking if you have it downloaded already

To check whether you already have a version of JDK, including JRE, downloaded, you’ll need to check on the command line. By typing:

Note that, depending on the IDE, it may be necessary to install the Java Development Kit (JDK) separately and provide a path for this as well. To install JDK, go to this page on Oracle.com and download the latest version. Once done, click on the.exe file and follow the steps by clicking Next. Java Development Kit for Mac includes a wide variety of tools for streamlined developing, debugging, testing, and monitoring of Java applications. The package contains more than 30 individual tools and services which can be used to control every aspect of Java application development, from concept to final phase and deployment to end users.

into the command line and pressing enter, you should get one of the following messages.
Something that looks like:
> java version '1.8.0_121'
> Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
> Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

means you already have an up to date version of the JRE installed. This can be checked by looking at the version on the first line.
To check the version of the JDK, that is needed to write Java programs, type:
> javac -version
which will produce an output like: Downloadjavac 1.8.0_121
If you do not get a message that looks like those above or get one that says command not found, you will need to install JDK before you can start writing and compiling Java programs. Choose an operating system below, and follow the instructions to get started.

Java Development Kit Download For Mac

Java development on mac On some Mac systems, JDK has been pre-installed. So it’s important to double-check, as shown above, before trying to install another version.
  1. Download the JDK from here
  2. Double-click the Disk Image file in your Downloads folder and follow the instructions to install JDK/JRE.
  3. Check using the methods above that the JDK is correctly installed (javac -version).
  4. Start coding!

Linux – Ubuntu

There are several JDK implementations available for Linux and Ubuntu chooses OpenJDK as its default JDK. But we’re gonna choose the Oracle JDK 8, as in the other two sections on this page. Firstly you need to check, as above, whether there is an implementation of JDK installed. If OpenJDK is installed, you need to write the below into the command line: sudo apt-get purge openjdk-* Once this is completed, the next steps should be taken to install the Java Development Kit:
  • Download the JDK from here. Either the Linux x86 version for 32-bit systems or Linux x64 for 64-bit system “tar.gz” package.
  • We need to create a ‘Java’ directory within /usr/local/ directory and then move into that directory. This can be done as follows from the Terminal
    cd /usr/local
    sudo mkdir java
    cd /usr/local/java
  • You then need to extract the jar file into the directory you have created using the following:
    sudo tar xzvf ~/Downloads/filename.tar.gz Replacing filename with the name of the file you downloaded.
  • At this point, you should have two uncompressed binary directories in /usr/local/java. You now need to edit the system PATH file /etc/profile. sudo gedit /etc/profile
    Scroll to the end of the file and copy/paste the following code in. Then save and exit.
    JAVA_HOME=/usr/local/java/jdk1.8.0_20
    JRE_HOME=/usr/local/java/jre1.8.0_20
    PATH=$PATH:$JRE_HOME/bin:$JAVA_HOME/bin
    export JAVA_HOME
    export JRE_HOME
    export PATH
  • You now need to tell Ubuntu where your Oracle JDK files are, type the following into the Terminal:
    sudo update-alternatives --install '/usr/bin/java' 'java' '/usr/local/java/jdk1.8.0_20/bin/java'
    sudo update-alternatives --install '/usr/bin/javac' 'javac' '/usr/local/java/jdk1.8.0_20/bin/javac'
    sudo update-alternatives --install '/usr/bin/javaws' 'javaws' '/usr/local/java/jdk1.8.0_20/bin/javaws'
  • Now you need to tell Ubuntu which JDK you want to be the default option:
    sudo update-alternatives --set java /usr/local/java/jdk1.8.0_20/bin/java
    sudo update-alternatives --set javac /usr/local/java/jdk1.8.0_20/bin/javac
    sudo update-alternatives --set javaws /usr/local/java/jdk1.8.0_20/bin/javaws
  • The next step is to reload your system wide PATH /etc/profile:
    source /etc/profile
  • You can then check that it is installed properly using javac -version
  • Reboot your computer and start coding!

Windows

  • Download the JDK from here
  • Run the installer, accepting all the default options and following the on screen instructions
  • Using File Explorer, check the files that have been installed, taking note of the upgrade number for example jdk1.8.0_25
  • You will need to edit your PATH environment variable. For Windows 7/8/10, do the following:
  • Launch the Control Panel and choose the System and Security or System option. Click on Advanced System Settings.
  • Choose the Advanced table, and click the Environment Variable option
  • Under System Variables, scroll until you see the Path option and choose Edit
  • For Windows 10:
    Click New for the table of existing PATH entries and enter the directory in which the JDK is in, for example
    c:Program FilesJavajdk1.8.0_xxbin where xx is the two numbers you remembered earlier (for example 25)
  • For older Windows operating systems:
    Put “c:Program FilesJavajdk1.8.0_xxbin”, replacing the xx as above, in the ‘Variable value’ in front of all the existing directories, followed by a semi-colon (;). Don’t delete any other existing entries as you may have other programs that use these!
  • Use javac -version to check that the JDK is installed correctly.
  • Start coding!
Now that you have installed the JDK, you can write your first Java program. You can learn exactly how to do that here!

Oracle JDK 15 is distributed in archive files (tar.gz and zip) and installer programs for popular operating systems like Windows, Linux and Mac. For Windows, I recommend you to download a setup program which makes the installation easy (automatic update environment variables and file associations).So head over to Oracle’s official Java SE Download page, and choose to download Windows x64 Installer. Then you will get a file named Developmentjdk-15_windows-x64_bin.exe downloaded onto your computer.After download, I recommend you to verify the integrity of the downloaded file by running the following command:

certutil –hashfile jdk-15_windows-x64_bin.exe SHA256

Then compare the outputted SHA256 value with the one published on Oracle’s website here. If two checksums match, you can safely run the setup program.
