Go to your command line and type in 'javac' and if a big list of words come up, then it worked.) Installing JDK for Mac: 1. Press the Apple Logo at the top-left of. Java SE Development Kit 8 Downloads. Thank you for downloading this release of the Java™ Platform, Standard Edition Development Kit (JDK™). The JDK is a development environment for building applications, applets, and components using the Java programming language.
This topic includes the following sections:
System Requirements for Installing the JDK on 64-Bit Windows Platform
For supported processors and browsers, see Oracle JDK Certified Systems Configurations.
JDK Installation Instruction Notation for Windows
For any text in this document that contains the following notation, you must substitute the appropriate update version number:
interim.update.patch
For example, if you are downloading the JDK installer for 64-bit systems for update 11 Interim 0, Update 0, and Patch 0, then the file name
jdk-11.interim.update.patch_windows-x64_bin.exe
becomes jdk-11_windows-x64_bin.exe
. JDK Installation Instructions for Windows
You run a self-installing executable file to unpack and install the JDK on Windows computers.
Install JDK on Windows computers by performing the actions described in the following topics:
Downloading the JDK Installer
Access Java SE Downloads page and click Accept License Agreement. Under the Download menu, click the Download link that corresponds to the
.exe
for your version of Windows. Download the file
jdk-11.interim.update.patch_windows-x64_bin.exe
. Note:
Verify the successful completion of file download by comparing the file size on the download page and your local drive. Alternatively, you can ensure that the downloaded file's checksum matches the one provided on the Java SE Downloads page. Running the JDK Installer
You must have administrator privilege to install the JDK on Microsoft Windows.
- Start the JDK 11 installer by double-clicking the installer's icon or file name in the download location.
- Follow the instructions provided by the Installation wizard.
- After the installation is complete, delete the downloaded file to recover the disk space.
Installing the JDK Silently
Instead of double-clicking or opening the JDK installer, you can perform a silent, non interactive, JDK installation by using command-line arguments.
The following table lists example installation scenarios and the commands required to perform them. The notation jdk stands for the downloaded installer file base name, such as
jdk-11_windows-x64_bin.exe
. Installation Scenario | Command |
---|---|
Install JDK in silent mode. | |
Install development tools and source code in silent mode. |
Setting the PATH Environment Variable
It is useful to set the
PATH
variable permanently for JDK 11 so that it is persistent after rebooting. If you do not set the
PATH
variable, then you must specify the full path to the executable file every time that you run it. For example: To set the
PATH
variable permanently, add the full path of the jdk-11bin
directory to the PATH
variable. Typically, the full path is:- Select Control Panel and then System.
- Click Advanced and then Environment Variables.
- Add the location of the
bin
folder of the JDK installation to thePATH
variable in System Variables.Note:ThePATH
environment variable is a series of directories separated by semicolons (;) and is not case-sensitive. Microsoft Windows looks for programs in thePATH
directories in order, from left to right.You should only have onebin
directory for a JDK in the path at a time. Those following the first instance are ignored.If you are not sure where to add the JDK path, append it.The new path takes effect in each new command window that you open after setting thePATH
variable.The following is a typical value for thePATH
variable:
Beginning to Use the JDK
Use the Java Development Kit in the Windows Start menu to access information related to Reference Documentation.
During JDK install, Java menu items are added to the Windows Start menu to provide easy access to Reference Documentation, which is online documentation web page.
During JDK installation and uninstallation processes, the appropriate start menu items are updated so that they are associated with the latest JDK version on the system
Note:
The Windows 7 and Windows 10 have a Installing Jdk On Mac
Start menu; however, the menu is not available in Windows 8 and Windows 8.1. The JDK and Java information in Windows 8 and Windows 8.1 is available in the following Start directory:![Java Java](https://documentation.sisense.com/Resources/Images/8-2/mceclip2.png)

To find the UninstallString, see Finding the JDK Registry Key and UninstallString Value .
- This command can be run from anywhere.
- The
msiexec.exe
executable is located in the windows system directory. - A reboot is required only if some files are in use during uninstallation; it is not necessary everytime. However, to manually suppress reboot while uninstalling, append
REBOOT=R
option to the command. - Append
/l “C:<path>setup.log”
option to the command if you want to create a log file describing the uninstallation status.
Windows Installer dialog appears prompting you for confirmation. Click Yes to uninstall JDK.

- Note the value of the UninstallString.
JDK Installation Troubleshooting
The following sections provide tips for resolving issues, if any, while installing JDK.
System Error During Decompression
If you see the error message:
system error during decompression
, then there might not be enough space on the disk that contains the TEMP
directory. Program Cannot Be Run in DOS Mode
If you see the error message:
This program cannot be run in DOS mode
, then do the following: - Open the MS-DOS shell or command prompt window.

Characters That Are Not Part of the System Code Page
A 1722 error may occur if the installation directory is not part of the system locale's code page. To prevent this, ensure that the user and system locales are identical, and that the installation path contains only characters that are part of the system locale's code page. User and system locales can be set in the Regional Options or Regional Settings control panel. The associated bug number is 4895647.
Cleanup the Registry After a Failed JDK Uninstall
Sometimes, attempts to uninstall JDK through the Windows Add/Remove program leave behind some Java entries in the registry that are not fully removed. These left behind registry entries can cause problems in installing a new version of Java. The following are the methods to cleanup registry entries:
- Program Install and Uninstall troubleshooter (Recommended Method)
- Manual Registry Edit
Program Install and Uninstall troubleshooter (Recommended Method)
Run the Program Install and Uninstall troubleshooter to repair the corrupted registry keys that prevent programs from being completely uninstalled, or blocks new installations and updates.
Manually edit the registry (Use this only if the Fix It utility does not work)
Incorrectly editing your registry may severely damage your system. You should back up any valued data from your computer before making changes to the registry.
Use the
File->Export
functionality of the registry editor to save the registry key before deleting. In case you deleted the wrong registry key, you can restore the registry from your saved backup file, by using the File->Import
functionality. To delete the registry key:
- Determine the correct Registry Key. See Finding the JDK Registry Key and UninstallString Value.
- Highlight the key, Right click and select Delete.
- Click Yes when prompted.
The JDK gets uninstalled.
