15 JDK Installation for Microsoft Windows

This page describes how to install and uninstall JDK 8 for Windows.

The page has these topics:

See «JDK 8 and JRE 8 Installation Start Here» for general information about installing JDK 8 and JRE 8.

System Requirements

See http://www.oracle.com/technetwork/java/javase/certconfig-2095354.html for information about supported platforms, operating systems, and browsers.

See «Windows System Requirements for JDK and JRE» for minimum processor, disk space, and memory requirements.

The JDK and JRE have a version string that enables you to determine the version number. See http://www.oracle.com/technetwork/java/javase/jdk8-naming-2157130.html for information about Java SE 8 version numbers.

The JDK has the option of installing the public JRE. For more information about JRE installation, see «JRE Installation for Microsoft Windows».

Installation Instructions Notation

For any text in this document that contains the following notation, you must substitute the appropriate update version number:

Installation Instructions

In these instructions, you run the self-installing executable file to unpack and install the JDK. As part of the JDK, this installation includes an option to include the public Java Runtime Environment. (The JDK also contains a private JRE for use only by its tools; see «Private Versus Public JRE» for more information.)

Install the JDK by doing the following:

Downloading the Installer

If you save the self-installing executable file to disk without running it from the download page at the web site, note the file size specified on the download page. After the download has completed, verify that you have downloaded the complete file.

Running the JDK Installer

You must have administrative permissions in order to install the JDK on Microsoft Windows.

Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory. Installers for JDK 7u2 to 7u5 install the JDK first, then start the JavaFX SDK installer, which installs JavaFX SDK in the default directory C:\Program Files\Oracle\JavaFX 2.0 SDK or C:\Program Files (x86)\Oracle\JavaFX 2.0 SDK on 64-bit operating systems. If you want to install the JavaFX SDK (version 2.0.2) with JDK 7u1 or earlier, see http://docs.oracle.com/javafx/2/installation/jfxpub-installation.htm for more information.

Java Start Menu

Starting with JDK 7u40 release, Java menu items are added to the Windows Start Menu to provide easy access to Java resources.

During JDK install, a Java Development Kit folder is created in the Windows Start Menu, which contains the following items:

Reference Documentation: Opens the Online API documentation web page.

Java Mission Control: Opens the Java Mission Control profiling and diagnostics tools suite.

During JDK install and uninstall processes, the appropriate start menu items are updated to be associated with the latest JDK version on the system

Java Mission Control is a commercial feature available to users with a Java SE Advanced license.

Installing the JDK Silently

Updating the PATH Environment Variable

If you do not set the PATH variable, you need to specify the full path to the executable file every time you run it, such as:

It is useful to set the PATH variable permanently so it will persist after rebooting.

Click Start, then Control Panel, then System.

Click Advanced, then Environment Variables.

Add the location of the bin folder of the JDK installation to the PATH variable in System Variables. The following is a typical value for the PATH variable:

The PATH environment variable is a series of directories separated by semicolons ( ; ) and is not case-sensitive. Microsoft Windows looks for programs in the PATH directories in order, from left to right.

You should only have one bin 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 you open after setting the PATH variable.

Starting to Use the JDK

Use the Java item in the Windows Start menu to get access to essential Java information and functions, including help, API documentation, the Java Control Panel, checking for updates, and Java Mission Control.

If you are new to developing and running programs in the Java programming language, see http://docs.oracle.com/javase/tutorial for some guidance. Note especially the tutorial trails under the heading Trails Covering the Basics.

Uninstalling the JDK

To uninstall the JDK, use the «Add/Remove Programs» utility in the Microsoft Windows Control Panel.

Uninstalling the JDK in Silent Mode

You can use the command line for uninstalling the JDK.

For example, to uninstall Java 8 update 251, run the command:

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.

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.

Finding the JDK Registry Key and UninstallString Value

Go to Start and type regedit.

Under the Uninstall folder, you will find many registry entries within curly brackets.

Click Edit and then Find.

Highlight Uninstall folder before performing search for a particular registry.

Enter version string as value to find corresponding registry key. Follow format 1.8.0.xxx. For example, enter jre1.8.0.251.

The registry key is highlighted on the right-hand side of the pane and values of various uninstall strings are displayed on the left-hand pane.

Note the value of the UninstallString.

Installed Directory Tree

See http://docs.oracle.com/javase/8/docs/technotes/tools/windows/jdkfiles.html for a description of the directory structure of the JDK. (Note that the file structure of the JRE is identical to that of the JDK’s jre directory.)

Installation Troubleshooting

Below are some tips for working around problems that are sometimes seen during or following an installation:

Corrupt Cabinet File

If you see the error message «corrupt cabinet file,» then the file you have downloaded is corrupted. Check the file size against the expected file size listed in these instructions. If sizes do not match, try downloading the bundle again. (A cabinet file contains compressed application, data, resource, and DLL files.)

System Error During Decompression

If you see the error message «system error during decompression,» then you might not have enough space on the disk that contains your 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.

Right-click the title bar.

Choose the Program tab.

Click the Advanced button.

Ensure that the item «Prevent MS-DOS-based programs from detecting Windows» is not selected.

Exit the MS-DOS shell.

Restart your computer.

Private Versus Public JRE

Installing the JDK also installs a private JRE and optionally a public copy. The private JRE is required to run the tools included with the JDK. It has no registry settings and is contained entirely in a jre directory (typically at C:\Program Files\jdk1.8.0\jre ) whose location is known only to the JDK. On the other hand, the public JRE can be used by other Java applications, is contained outside the JDK (typically at C:\Program Files\Java\jre1.8.0 ), is registered with the Windows registry (at HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft ), can be removed using Add/Remove Programs, might be registered with browsers, and might have the java.exe file copied to the Windows system directory (which would make it the default system Java platform).

Source Files in Notepad

Characters That Are Not Part of the System Code Page

It is possible to name directories using characters that are not part of the system locale’s code page. If such a directory is part of the installation path, then generic error 1722 occurs, and installation is not completed. Error 1722 is a Windows Installer error code. It indicates that the installation process has failed. The exact reason for this error is not known at this time.

To prevent this problem, 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.

Установка JDK в Windows

В этой статье мы установим JDK 11 на Windows. Java Development Kit (JDK) – это набор программ и библиотек для разработки программ на Java. Если вы хотите разрабатывать на Java программы, сперва вам нужно установить актуальную версию JDK.

В данной статье мы покажем, как установить JDK 11. Эта версия LTS (long time support), которая будет поддерживаться до сентября 2022 года. Вы можете установить любую другую версию JDK на ваш вкус, используя эту инструкцию.

Как установить JDK

Скачайте нужный дистрибутив JDK

На следующей страницу выберите дистрибутив «Windows x64 Installer»:

Появится всплывающее окно. Согласитесь с условиями лицензии и нажмите кнопку Download:

Для скачивания вам потребуется залогиниться в существующую учётную запись Oracle. Если у вас её нет, вы можете создать новую учётную запись.

Если вам лень заморачиваться с созданием учётных записей, найдите работающий логин/пароль на сайте bugmenot

Начнётся скачивание инсталлятора. По окончанию загрузки запустите установку:

На этапе выбора компонентов укажите путь установки. Я крайне рекомендую вам заменить стандартный путь C:\Program Files путём, не содержащих пробелов, например, C:\Java\jdk-11

Через несколько минут установка завершится:

Для проверки вы можете зайти в указанный вами путь и проверить, что там есть следующий контент:

Настройка переменных окружения

После успешной установки JDK, крайне желательно объявить переменную окружения JAVA_HOME. Эта переменная используется многими программами и инструментами из стандартного набора Java разработчика.

Для этого откройте окно «Этот компьютер» → «Свойства»:

Затем откройте окно «Дополнительные параметры системы» и в нём нажмите кнопку «Переменные среды…»

В окне «Переменные среды» нажмите кнопку «Создать…»

В появившемся окне введите следующие значения:

Имя переменной: JAVA_HOME
Значение переменной:

Затем найдите системную переменную Path и измените её:

Нажмите кнопку «Создать», и укажите в новой строке значение %JAVA_HOME%\bin

Также, если вы видите в этом списке путь к программе javapath (как на скриншоте), удалите его.

Проверка установки

После установки переменных окружения откройте консоль (Win+R, cmd)

Последовательно выполните две команды:

Если вы видите вывод наподобие этого, значит, вы корректно установили JDK и правильно указали переменные окружения. Вы готовы написать свою программу на Java!

Резюме

В данном уроке мы научились устанавливать JDK и настраивать перменные окружения. В следующих уроках мы установим основные инструменты Java программиста.

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)

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:

Click Yes when prompted.

The JDK gets uninstalled.
