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

Go to the Oracle website. You'll see something like this:
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.
Open your Downloads folder, and double-click on jdk-8u65-macosx-x64.dmg. You'll see this window:
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

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.
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.
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.
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.
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.
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.
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.
You'll get an empty workbench like this:
FeaturesIt has got features that allows yo u to show applications on your phone vi a cloud. Applications that may harm your phones can be run on your PCs by the help of BlueStacks. GamingIt is developed for Gaming. Download bluestacks 5 for pc windows 10. It provides best gaming platform with advance features like mouse mapping in the game etc.
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.

How To Download Jdk For Mac

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.
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:
In the window in the middle, click on the triangle next to Java. Then double-click on 'Java Editor Text Font':
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.
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:
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.
You should see a window like this:
Change the tab size to 2:
You'll see that the indentation size automatically changes as well.
Click on 'Blank Lines,' and after 'Between import groups' and 'Before declarations of the same kind,' change the values 1 to 0:
Click on 'Control Statements,' and check the first four boxes as I've done here:
Click OK.
Now click on triangles to close up Java. Click on the triangle next to Run/Debug, and then click on Console:
Click on the green color sample next to 'Standard In text color.' You'll get a color picker:
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.

And you're done!

Question or issue on macOS:

I want to install a specific JDK (the latest for example). For this, I went to the JDK download homepage: http://java.sun.com/javase/downloads/index.jsp.
I looked for a Mac version, but I’m a bit surprised to only see downloadable versions for Linux, Windows and Solaris…

Here’s the message for Mac:

OK BUT… when I update Java with Mac I have a JRE and not a JDK…

I don’t understand why a JDK version doesn’t exist that is easily downloadable/installable (like a jar to unzip?) for Mac…

How to solve this problem?

Solution no. 1:

In a comment under @Thilo’s answer, @mobibob asked how to set JAVA_HOME in your .bash_profile on a Mac. Answer:

This will dynamically assign to JAVA_HOME the location of the first JDK listed in the “General” tab of “Java Preferences” utility.

See Apple Technical Q&A 1170: https://developer.apple.com/library/content/qa/qa1170/_index.html

EDIT:

If you prefer parentheses to backticks for command substitution, this also works:

Solution no. 2:

As the message says, you have to go to Apple, not Sun, for Java on the Mac. As far as I know, Apple JDK 6 is installed by default on Mac OS X 10.6 (Snow Leopard). Maybe you need to install the developer tools from your Mac OS X installation DVD (the dev tools are an optional install from the OS DVD).

See: http://developer.apple.com/java/

NOTE This answer from 16 Oct 2009 is now outdated; you can get the JDK for Mac OS X from the regular JDK download page on Oracle’s website now.

Solution no. 3:

For people using any LION OS X 10.7.X

They uploaded Java SE 6 version 1.6.0_26 available here

Solution no. 4:

I bought a MacBook Pro yesterday (Mac OS X v10.8 (Mountain Lion)) and there is no JDK installed by default…

As well as javac, I also found it didn’t have packages such as SVN installed. It turns out you can get everything from the Apple developer page (you will need to register with your AppleID). SVN is part of the “Command Line Tools” package.

This is what happens on a fresh MacBook:

Hopefully this will help out other newbies like me 😉

Solution no. 5:

Mac comes with the JDK, for more information check:

Solution no. 6:

The explanation is that JDK is a bit specific and does not contain the library tools.jar. For my development, I need this library and Mac’s JDK doesn’t provide it:

(Cf. http://developer.apple.com/mac/library/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html)

tools.jar does not exist. Classes usually located here are instead included in classes.jar. Scripts that rely on the existence of tools.jar need to be rewritten accordingly.

It sucks!

Solution no. 7:

The easiest way is to use Homebrew.
Install Homebrew and then:

You can list all available versions using the following command:
brew cask search java

Solution no. 8:

Compiling with -source 1.5 -target 1.5 (in a JDK 6 environment) will honor only language elements that were in 1.5 and prior. Great. But there were no language changes in 6 anyway. Problem with this approach (on Mac with 1.6) is that using classes that came AFTER 1.5 will still compile because they exist in the rt.jar. So one could run in a 1.5 env and get a class not found exception with no prior warning when compiling. I found this out the hard way with javax.swing.event.RowSorterEvent/Listener. Both entered “Since 1.6” but are not caught with -source 1.5

Solution no. 9:

If you installed brew, cmd below will be helpful:

brew cask install java

Solution no. 10:

As of Mac OS X v10.6 (Snow Leopard), you can run Java 6 in 32-bit mode on either 32-bit or 64-bit Intel processor equipped Macs.
