Nov 11, 2019 How to Install the Java Development Kit (JDK) for Mac. For example, to uninstall the JDK 8u6: sudo rm -rf jdk1.8.006.jdk Download Java SDK. Download the JDK.dmg file here.

We’ll first start with how to download and install JDK on Windows 10. Then, we’ll highlight how to accomplish the same thing in Mac.

Lastly, we’re going to explain how to install JDK on Ubuntu.

So, let’s get started!

Java

What is JDK?

JDK is the abbreviation of the Java Development Kit, a package that offers an environment for developing, debugging, and monitoring Java-based applications.

In short, JDK provides a set of ready-to-use tools that we can use to build java programs.

Before installing JDK, we need first to check if it’s already installed (or not) on our operating system.

Now, let’s get down the rabbit hole and see how to install Java JDK on Windows 10, Mac, and Ubuntu.

How to Install Java JDK on Windows 10

First thing first, let’s explore how to check whether Java JDK is already installed on our windows 10 machine.

  • Go to the search bar and type CMD

  • Open the command prompt from the search result

  • When the command prompt opens, type this command: javac –version.

If the response is something like:

Then, this simply means that JDK is not installed on your Windows 10.

Obviously, we need to download the JDK package before starting the installation process. To do that, please refer to the following article: How to install Java on Windows 10.

Finally, we need to add the JDK bin directory to the PATH. The PATH variable points to the location of the executables: javac and java.

Please bear in mind that if we don’t add JDK to the PATH, then we need to specify the full path for the executables every time we want to compile or run a Java program.

In other words, to compile myProgram.java, we need to run:

Instead of:

Install JDK on Mac

First, we need to verify if JDK has been already installed on our Mac. To do so, follow these steps:

  • Click the Launchpad icon, then type Terminal in the search field

  • Open the terminal

  • Type the javac -version command

If you got command not found message, then JDK is not installed.

In case the JDK is not installed, then we need to download it first:

  • Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html to download the last version of the JDK

  • Accept the license agreement and download the latest JDK version for your Mac OS

The process of installing Java JDK on Mac is pretty easy and straightforward:

  • Open the .dmg file to start the installation wizard

  • Click Continue and then Install

  • Enter your credentials and click Install Software

  • Once the installation is completed, a confirmation alert will be displayed

  • After the installation, you will be asked to keep or delete the package file. (You can choose the delete option to save some disk space)

Install JDK on Ubuntu

The first step is always checking whether JDK is installed or not. To do so, type the following command lines:

As shown above, JDK is already installed on my Ubuntu machine.

Installing the Default OpenJDK

The easiest option for installing Java JDK on Ubuntu is to install the default OpenJDK which is an open-source implementation of the Java SE Platform Edition.

Before starting the installation process, we need to update the apt package. Open a terminal (Ctrl+Alt+T) and type:

Next, install the default Java OpenJDK package with:

That’s it, the above command will simply install Java 11 or a newer version. Congratulations, you successfully installed OpenJDK on Ubuntu.

Please keep in mind that we can install a specific version - for example Open JDK 8 - instead of the default OpenJDK 11.

To do so, type the following command line:

Now, let’s take a look at how to install the Oracle’s official JDK.

Installing Oracle JDK

Starting with Java 11, Oracle JDK is licensed under Oracle Binary Code License Agreement. This means that we can no longer use Java for business or production purposes without a commercial license.

To install the official Oracle JDK, we first have to create an Oracle account to download the JDK version we need.

Please keep in mind that we need a third-party installation script from here, since we can’t install JDK directly through package managers.

One another important thing to mention is that the downloaded JDK version must match the third-party installation script version.

So firstly, we need to add the PPA repository using the command below:

Once the PPA repository is added, we can proceed to install Java JDK on Ubuntu.

Secondarily, let’s download JDK from the Oracle official downloads page. Find the version you need and download it.

At the time I’m writing this article, the latest JDK version is 16.0.1. So, let’s click on jdk-16.0.1_linux-x64_bin.tar.gz package for Linux.

Next, we need to transfer the downloaded file to our Ubuntu server using scp command:

Now, let’s move jdk-16.0.1_linux-x64_bin.tar.gz to the /var/cache/oracle-jdk11-installer-local directory.

Finally, we’ll install Oracle JDK with the help of the following command line:

This page tells you how to download and install Java 8 and Eclipse on Mac OS X, and how to configure Eclipse.

Installing Java 8

  1. Go to the Oracle website. You'll see something like this:

  2. Scroll down until you see a heading beginning 'Java SE 8u65/8u66.' On the right, you'll see a Download button under the JDK header. Click it. The next screen will look like this:

    Click the radio button next to 'Accept License Agreement' and then click on jdk-8u65-macosx-x64.dmg. You'll be asked whether to save the file that is going to be downloaded; click on Save File.

  3. Open your Downloads folder, and double-click on jdk-8u65-macosx-x64.dmg. You'll see this window:

  4. Double-click on the package icon, and follow the instructions to install. When the installation has completed, click on Done. At this point, you may close up the window and drag jdk-8u65-macosx-x64.dmg to the Trash.

Installing Eclipse

  1. If you already have Eclipse installed on your Mac, you need to get rid of it. To do so, first quit Eclipse if you're currently running it. Then, go to your workspace folder (probably in Documents/workspace) and save anything there that you want to keep, because you're about to get rid of this folder. Next, drag the workspace folder to the Trash.

    Go to your Applications folder. One way to get there is, from the Finder, type command-shift-A. You'll a folder named eclipse in there; drag the eclipse folder to the Trash. If you have an Eclipse icon in your dock, remove it from the dock.

  2. Now you're ready to download and install the newest version of Eclipse. Go to this website. You'll see a window like this:

    Scroll down until you see 'Eclipse IDE for Java Developers' and click where it says 64 bit under Mac OS X.

  3. You will see this window:

    Click on the yellow download button. If asked, click on 'Open with Archive Utility (default)' and then click OK. The download might take a few minutes. You should not feel compelled to donate.

  4. After the download completes, folders should automatically expand. If they don't, double-click on the .tar file. When that's done, you should see a folder named eclipse in your Downloads folder. When you open your Downloads folder, if you see Applications under the Favorites on the left side of the window, you should drag the eclipse folder into Applications. If you don't see Applications, then open a new window for Applications (from the Finder, command-shift-A), and drag the eclipse folder into Applications.

  5. Open your Applications folder, and then open the eclipse folder. You'll see an item named Eclipse; if you like, drag its icon into the dock so that you'll be able to launch Eclipse easily.

  6. Launch Eclipse. If you're asked whether you want to open it, of course you do; click Open. You'll see a window like this:

    It will have your user name rather than mine (scot). Select where you want your workspace to be; I recommend the default of your Documents folder. Click the checkbox for using this location as the default, and then click OK.

  7. You'll see a window like this:

    Click on the Workbench arrow in the upper right that I've circled. You shouldn't see this screen again, even if you quit Eclipse and relaunch it.

  8. You'll get an empty workbench like this:

    We won't be using the 'Task List' and 'Connect Mylyn' windows. Click the 'x' on each to close it. Press the mouse on the Window menu item, then choose 'Perspective', and finally choose 'Save Perspective as..'. Enter 'cs10' for the name of this perspective and press return. Your workbench will now look like this:

    You have now installed Eclipse!

Configuring Eclipse

You don't have to configure Eclipse the way I do, but you'll probably avoid some confusion if you do. Here's how.

  1. In the Eclipse menu bar, click on the Eclipse menu and then on 'Preferences..'. You'll see a window with two panes. On the left pane is a list of types of things you can configure.

  2. Click on the triangle to the left of General. Then click on the triangle to the left of Appearance. Then click on 'Colors and Fonts.' You should see a window like this:

  3. In the window in the middle, click on the triangle next to Java. Then double-click on 'Java Editor Text Font':

  4. You'll see this window:

    On the right, where you can select the size, click 12. Then close this window by clicking on the window's close button.

  5. Close up the General preferences by clicking on the triangle to the left of General. Click the triangle next to Java and then click the triangle next to 'Code Style.' Then click Formatter. Here's what you should see:

  6. Click the button that says 'New..'. You'll see a window such as this one:

    You can type in any profile name you like. I used 'CS 10':

    Click OK.

  7. You should see a window like this:

    Change the tab size to 2:

    You'll see that the indentation size automatically changes as well.

  8. Click on 'Blank Lines,' and after 'Between import groups' and 'Before declarations of the same kind,' change the values 1 to 0:

  9. Click on 'Control Statements,' and check the first four boxes as I've done here:

    Click OK.

  10. Now click on triangles to close up Java. Click on the triangle next to Run/Debug, and then click on Console:

  11. Click on the green color sample next to 'Standard In text color.' You'll get a color picker:

  12. Slide the slider on the right down, so that you get a dark green. (You're at Dartmouth. What other color could you possibly want?)

    Close the color picker window by clicking its close button, and click OK again to close the Preferences window.

    13. And you're done!
