This page tells you how to download and install Java 8 and Eclipse on Mac OS X, and how to configure Eclipse.
Updating from Java 8 update 60 to Java update 71 on a Mac – DavidPostill Feb 7 '16 at 9:50 I accepted the answer. From what I have learned, the 'new helper tool' is the installation program. The goal of this Project was to produce an open-source reference implementation of the Java SE 8 Platform Specification defined by JSR 337 in the Java Community Process. Production-ready binary distributions based on the JDK 8 code base are available now from Oracle and will be available soon in most Linux distributions.
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:
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.
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!
Direct Download Java for Windows 10. Java offline installer, Java 8 offline installer.
Java 8 Update 131 is released by Oracle which incorporates various important changes, security fixes and new features. This latest Java 8 update enhances the security of the system, therefore, it is recommended to update your current Java Runtime Environment to Java SE 8 Update 131.
In this blog post, we are providing Java 8 Update 131 offline installer for Windows, Linux , Solaris and Mac PCs. The latest Java 32 bit or Java 64 bit standalone installer setup doesn’t require Internet connectivity while installation. Even you can use the Java offline installer multiple times.
The next updates will be available for download in July 2017 as the expiry of Java 8U 131 release is July 18, 2017. Make sure you have latest Java updates to avoid security threats.
The List of Changes and Features Introduced in Java 8 Update 131 Offline Installer
MD5 Added to jdk.jar.disabledAlgorithms Security Property:
All the disabled algorithms and key sizes for cryptographically signed JAR files are stored & controlled in security property, jdk.jar.disabledAlgorithms. The latest Java JDK download has introduced new limitations on how MD5 (hashing algorithm) signed JAR files are verified. The applications that use signed JAR files are affected by this restriction as in case the signed JAR file uses the MD5 hash algorithm, the signature verification operations will treat that specific JAR file as unsigned.
The jarsigner binary can be used to verify whether the JAR file is signed by using a weak algorithm (MD5) or the strong one. The files signed with weak algorithm are disabled now with this latest update and that would be required re-signed by the strong algorithm.
New System Property to Control Caching for HTTP SPNEGO Connection:
The Java 8 runtime environment introduces new system property to control caching HTTP SPNEGO, according to which when connecting to HTTP server using SPNEGO in order to negotiate authentication and after the successful authentication of the connection, the specified information will be cached and reused for the next connections on the same server.
New System Property to Control Caching for HTTP NTLM Connection:
Java 8 Update 191 8u191
As per the new JDK implementation, HTTP NTLM can support transparent authentication. In case the transparent authentication is not available or unsuccessful, the Java Development Kit only supports getting credentials from the global authenticator.
If the connection to HTTP server using NTLM gets successful, the authentication information will be cached and reused for the next connections on the same server.
