Java ME Downloads Java Platform Micro Edition Software Development Kit 3.0 for Mac OS. Java ME Platform SDK is a state-of-the-art toolbox for developing mobile applications. It provides device emulation, a standalone development environment, and a set of utilities for rapid development of Java. 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.
1. Download Oracle JDK 15
Java Developer Kit For Mac
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 namedJdk Download For Mac
jdk-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.2. Install Oracle JDK 15
Double click the downloaded EXE file to launch setup program for Oracle JDK 15. You will see this dialog appears:Just click Next two times to proceed the installation with default settings. It will install Oracle JDK 15 quickly. And finally click Close to complete the installation.Now, open a new command prompt window and type the command java –version, you will see the version information of JDK like this:This means you have successfully installed Oracle JDK 15 on your computer. Note that the installer has updated the environment variables JAVA_HOME and PATH behind the scene. So it’s very convenient.To see the download and installation of Oracle JDK 15 in action, you can follow the video below:

To check whether you already have a version of JDK, including JRE, downloaded, you’ll need to check on the command line. By typing:> java -version
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:
javac 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.Mac OSX
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.
- Download the JDK from here
- Double-click the Disk Image file in your Downloads folder and follow the instructions to install JDK/JRE.
- Check using the methods above that the JDK is correctly installed (
javac -version
). - 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:Java Development Kit 32 Bit
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!
