When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.
Thank you for downloading this release of the JavaTM Platform, Standard Edition Development Kit (JDKTM). The JDK is a development environment for building applications, applets, and components using the Java programming language.

TheOracle Technology Network License Agreementfor Oracle Java SE is substantially different from prior Oracle JDK 8 licenses. This license permits certainuses, such as personal use and development use, at no cost -- but other uses authorized under prior Oracle JDKlicenses may no longer be available. Please review the terms carefully before downloading and using this product.FAQs are availablehere.
These downloads can be used for development, personal use, or to run Oracle licensed products. Use for otherpurposes, including production or commercial use, requires a Java SE subscription or another Oracle license.
The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.
After the download completes, folders should automatically expand. 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.
Throughout this section we will be using the wget command to download the Oracle Java software packages. wget may not be included by default on your Linux distribution, so in order to follow along you will need to install it by running:
Note: In order to install Oracle Java, you will need to go to the Oracle Java Downloads Page, accept the license agreement, and copy the download link of the appropriate Linux x86 .rpm package. Substitute the copied download link in place of the highlighted part of the wget command.
Due to limited intellectual property protection and enforcementin certain countries, the JDK source code may only be distributedto an authorized list of countries. You will not be able to accessthe source code if you are downloading from a country that is noton this list. We are continuously reviewing this list for additionof other countries.
1. The official Oracle JDK is not available for download from the local repository. You have to download the .rpm package from the Java SE Downloads page.
Prerequisite, Java must be available:Java is open source and can be downloaded from SQuirreL will always run with the current LTS (Long Term Support) release of Java.The minimum Java version required usually is the previous LTS release.Installation of the SQuirreL SQL Client on Windows and Linux/Unix:The SQuirreL SQL Client can be installed by the IzPack installer. Download the file squirrel-sql--standard.jarand execute it using the following command:java -jar squirrel-sql--standard.jar when you properly installed Java.or\bin\java -jar squirrel-sql--standard.jar when you just unpacked the zip or tar.gz version of Java.Note: On Linux/Unix replace backslashes (\) by slashes (/).Make sure that you have write privileges to the directorythat you want to install into.Note that some browsers may attempt to open thisfile rather than download it. In this case, right-click onthe download link and click your browser's equivalent of the"Save as..." menu item.Installation of the SQuirreL SQL Client on MacOS:On MacOS the preferable way to install the SQuirrel SQL Client is the MacOS X installer squirrel-sql--MACOSX-install.jar.Starting the SQuirreL SQL Client:On Windows, execute the file squirrel-sql.bat to run theapplication. On Linux/Unix and MacOS, the file is squirrel-sql.sh.Trouble shooting:When SQuirreL SQL doesn't start:On Windows try to add the line  set JAVA_HOME=to the top of squirrel-sql.batOn Linux/Unix or MacOS try to add the line  export JAVA_HOME=after the line  #! /bin/shof squirrel-sql.shScaling problems on high resolution screens:Set the JVM (Java Virtual Machine) parameter-Dsun.java2d.uiScale=Example: -Dsun.java2d.uiScale=2.5This can be done by editing squirrel-sql.bat on Windows and squirrel-sql.sh on Linux/Unix or MacOSor by setting the SQUIRREL_SQL_OPTS variable before executing the start script.
You will need to have a JRE version (32-bit or 64-bit) that is compatible with the architecture of the ApacheOpenOffice version you downloaded. If you already have a JRE installed on your system that satisfies this requirement inone of the standard areas for Java installation, OpenOffice should detect this installation and let you choose it for usein OpenOffice via the "Tools - Options... - Java". If you have a JRE installed that is not detected,you should be able to add it through this same menu. And, you can install a JRE or configure OpenOffice to use Java at anytime to get missing functionality to work.
The current versions of Apache OpenOffice work reliably with a variety of JREs includingOracle Java, versions 6, 7 and 8,openJDK, versions 6, 7 and 8 andAdoptium OpenJDK, versions 8 and 11. Feel free to download a JRE from either of these sitesif you feel you need this functionality.
For Windows users, after the Eclipse Installer executable has finished downloading it should beavailable in your download directory. Start the Eclipse Installer executable.You may get a security warning to run this file. If the Eclipse Foundation isthe Publisher, you are good to select Run.
Once installed in the Gradle User Home directory, a provisioned JDK becomes one of the JDKs visible to auto-detectionand can be used by any subsequent builds, just like any other JDK installed on the system.Since auto-provisioning only kicks in when auto-detection fails to find a matching JDK, auto-provisioning can only download new JDKs and is in no way involved in updating any of the already installed ones.None of the auto-provisioned JDKs will ever be revisited and automatically updated by auto-provisioning, even if there is a newer minor version available for them.
Gradle uses the public Adoptium and AdoptOpenJDK APIsby default to determine and download a matching JDK.Gradle first attempts to download a JDK from Adoptium. If Adoptium does not provide a matching JDK, Gradle attempts to download from AdoptOpenJDK.
Just like the different Java platforms, there are several Java implementations that you can install on your system. Ubuntu repositories provide an open-source Java implementation known as Open JDK and Open JRE. Oracle Java is another implementation that you can download, however, it's mostly used commercially.
Note that the website will ask you to sign in to your Oracle account. If you don't have an account, you can create one for free. As soon as you log in to your account, the download will start automatically.
To install the Oracle Java package that you just downloaded, go to the location where you saved the .deb file. Double-click on the file to launch Ubuntu Software Center. Click on the Install button to start installing Oracle Java on your system.
For Linux and MacOS is recomended to use the open-jdk-jre 1.8 or 1.7 included in your system. If they are not available on your system and you can not install them you can download from here.
For Linux is recomended to use the open-jdk-jre 1.7 or 1.6 included in your system. If they are not available on your system and you can not install them you can download from here.
Sun renamed the Oak language to Java after a trademark search revealed that Oak Technology used the name Oak.[42] Sun priced Java licenses below cost to gain market share.[43] Although Java 1.0a became available for download in 1994, the first public release of Java, Java 1.0a2 with the HotJava browser, came on May 23, 1995, announced by Gage at the SunWorld conference. Accompanying Gage's announcement, Marc Andreessen, Executive Vice President of Netscape Communications Corporation, unexpectedly announced that Netscape browsers would include Java support. On January 9, 1996, Sun Microsystems formed the JavaSoft group to develop the technology.[44]
According to Oracle in 2010, the Java Runtime Environment was found on over 850 million PCs.[63] Microsoft has not bundled a Java Runtime Environment (JRE) with its operating systems since Sun Microsystems sued Microsoft for adding Windows-specific classes to the bundled Java runtime environment, and for making the new classes available through Visual J++.[citation needed] Apple no longer includes a Java runtime with OS X as of version 10.7, but the system prompts the user to download and install it the first time an application requiring the JRE is launched.[citation needed] Many Linux distributions include the OpenJDK runtime as the default virtual machine, negating the need to download the proprietary Oracle JRE.[64]
Because OpenJDK is under the GPL, it is possible to redistribute a custom version of the JRE directly with software applications,[84][85] rather than requiring the enduser (or their sysadmin) to download and install the correct version of the proprietary Oracle JRE onto each of their systems themselves.
In recent years, researchers have discovered numerous security flaws in some widely used Java implementations, including Oracle's, which allow untrusted code to bypass the sandboxing mechanism, exposing users to malicious attacks. These flaws affect only Java applications which execute arbitrary untrusted bytecode, such as web browser plug-ins that run Java applets downloaded from public websites. Applications where the user trusts, and has full control over, all code that is being executed are unaffected. 2ff7e9595c
