JDK 23 is a regular update of the Java SE platform, released on September 17th 2024. Follow the steps below to set up the Java Development Kit (JDK) on your Windows operating system with Oracle JDK 23, a commercial distribution provided by Oracle corporation.

After completing this guide, you will have the Java runtime environment, as well as core Java development tools, installed — essentials to start your Java programming journey.

1. Download Oracle JDK 23 Installer for Windows

It’s strongly recommended to use an official installer or JDK 23. Visit the official Java downloads page, where you’ll find Oracle JDK 23 available as Zip file (x64 Compressed Archive), x64 Installer (EXE) and x64 MSI Installer:

Oracle JDK 23 download for Windows

For convenience (ease of setup), you can choose to download either the EXE or MSI installer. In this guide, I will choose the EXE installer, so click on the download link (1) next to x64 Installer. Save the file (jdk-23_windows-x64_bin.exe) to the Downloads folder in your user home directory.

2. Verify the Installer File

This step is option but recommended to ensure that the downloaded file is original and has not been tampered with. Open a new Command Prompt window and change the current directory to the Downloads folder using the following command:

cd Downloads

Then type the following command:

certutil -hashfile jdk-23_windows-x64_bin.exe sha256

This prints the SHA256 checksum value of the file. Go back to the Java downloads page and click on the sha256 link (2) next to the download link to view the SHA256 checksum of the original file. If both values match, it means the downloaded file is intact, and you can safely run it.

Double-click the .exe file to run the Windows installer for Oracle JDK 23. If you see the warning “the app you’re trying to install isn’t a Microsoft-verified app”, click Install anyway. This will launch the Setup program for Java(TM) SE Development Kit 23.0.1 (64-bit) as shown below:

Oracle JDK 23 Setup program for windows

If you want proceed the installation with default settings, click the Next button twice. The installation will be completed in just a few seconds, and JDK 23 will be installed in the C:\Program Files\Java\jdk-23 directory by default. There is no need to configure system environment variables.

4. Verify the Oracle JDK 23 Installation on Windows

Exit the Setup program. Then, open a new Command Prompt window, type in java -version to check version of the Java Virtual Machine (JVM). If you see a result similar to the following screenshot, it means JDK 23 has been installed successfully on your Windows computer:

check java version in command prompt

You can also type javac -version to check version of the Java compiler, and it will display “javac 23.0.1”.

Congratulations! You’ve done the first and foremost step to begin creating, developing, building and running Java applications on the Windows operating system using the Oracle JDK distribution for Java 23.

Java Development Kit (JDK) is one of the most important tools for developers who use it to build, compile, and run Java applications. It does not matter if you are a beginner or an experienced programmer; installing JDK is the first step towards working with Java development. We can download JDK to create and run Java applications on our system. Also, the JDK is used to create Android application source files as well, using the Java or Kotlin programming language. There are multiple benefits of installing a JDK.

Key Features of JDK:

  • Compiler (javac): Converts Java code into bytecode for JVM execution.
  • JRE + JVM: Includes runtime environment to execute Java programs.
  • Rich Libraries: Pre-built classes for I/O, networking, databases, and more.
  • Debugging Tools: JDK provides JDB (Java Debugger) for troubleshooting code.
  • Multi-Platform Support: JDK supports write-once, run anywhere (Windows, Linux, macOS).

The system will execute the code using a set of Libraries and Compilers. JDK, JRE, and JVM should not be confused with one another.

Refer to this article to learn more: Differences between JDK, JRE, and JVM.

Why Install JDK?

  • To develop and run Java applications
  • Compile Java source code (javac)
  • Includes JRE (Java Runtime Environment) and JVM (Java Virtual Machine)
  • Required for Android app development (Java/Kotlin)

This article describes the step-by-step process for installing and configuring the JDK on Windows, Mac, and Linux.

Начинаем разрабатывать на Java: где взять, как установить и настроить всё, что нужно.

 vlada_maestro / shutterstock

Пишет на Java. Верит в Agile. Пьёт много кофе и не любит грязный код.

Чтобы начать программировать на Java, нужно установить комплект разработчика приложений (SDK). Он позволит запускать, отлаживать и исполнять наши первые программы. Также нам понадобится среда разработки (IDE), где мы и будем писать код.

Пройдём через это вместе. Установим JDK в Windows, Ubuntu и macOS, и IntelliJ IDEA тоже в Windows, Ubuntu и macOS. Поехали!

Java Development Kit (JDK) — это комплект ПО для разработчиков приложений на Java. Стандартная установка включает в себя интерпретатор, облегчённый интерпретатор JRE, компилятор, библиотеку Java-классов, отладчик, средства архивации и сжатия jar и другое.

Чтобы установить JDK в Windows, нужно:

  • загрузить актуальную версию пакета,
  • установить его,
  • настроить переменные окружения.

Нам нужна бесплатная версия — AdoptOpenJDK (она есть под Windows, macOS, Ubuntu и другие платформы).

Идём сюда и выбираем версию JDK (актуальны версии 8+), виртуальную Java-машину (JVM) и свою платформу.

Я выбрал OpenJDK 11 (LTS), HotSpot и Windows x64 jdk соответственно:

Скачиваем файл по появившейся ссылке (я выделил её жёлтым на скрине выше).

Извлекаем скачанный архив в папку C:\Program Files\Java\

При этом будет создана подпапка jdk-*номер версии*, а внутри неё появится папка bin.

В результате полный путь до папки bin у меня выглядит так:

C:\Program Files\Java\jdk-11.0.2\bin

Нам нужно создать системную переменную JAVA_HOME, которая будет хранить путь до нашей версии JDK. Это понадобится программам для работы с проектами Java.

Заходим в Панель управления → Система → Дополнительные параметры системы → Дополнительно

А можно и прямо в Панели управления вбить в поиск слово «переменных» (без кавычек). ОС предложит варианты, из которых выбирайте «Изменение системных переменных среды».

У вас откроется окно:

Здесь жмём на кнопку «Переменные среды».

В новом окне для раздела «Системные переменные» кликаем «Создать». В «Имя переменной» вводим JAVA_HOME (именно так, латиницей в верхнем регистре), а в поле «Значение переменной» подставляем наш путь C:\Program Files\Java\jdk-*номер версии*:

Далее в разделе «Переменные среды» редактируем системную переменную Path. Нужно добавить в неё путь к папке с исполняемыми файлами Java, а именно: %JAVA_HOME%\bin (соблюдайте регистр символов):

Перезагружаем Windows.

Запускаем Командную строку Windows. Для этого нажимаем Win + R, а в появившемся окне вводим cmd.exe и жмём на Enter.

В открывшейся консоли набираем javac -version и жмём ввод.

Если установка прошла успешно, то ответ покажет версию вашего компилятора:

Рассмотрим установку JDK на одном из самых популярных дистрибутивов Linux — Ubuntu 20.04 (LTS).

Проще всего установить версию, которая входит в пакет Ubuntu. По умолчанию в Ubuntu 20.04 входит версия Open JDK 11.

Открываем терминал сочетанием клавиш Ctrl + Alt + T и обновляем базу данных пакетов с помощью APT:

Проверяем ранее установленные версии командой:

Если установка уже выполнялась, то мы увидим что-то такое:

Для запуска любых приложений Java нужна JRE (Java Runtime Environment — среда выполнения для языка Java). Но для компиляции и разработки программ требуется JDK (Java Development Kit).

Чтобы установить JRE, вводим в консоль:

$ sudo apt install default-jre

Для установки JDK — команду:

$ sudo apt install default-jdk

Вводим команду:

Ответ должен выглядеть примерно так:

Этот способ установки использует HomeBrew (менеджер недостающих пакетов для macOS).

Прежде всего нужно добавить репозиторий в HomeBrew. Для этого открываем терминал (Cmd + N) и вводим:

$ brew tap AdoptOpenJDK/openjdk

Устанавливаем OpenJDK 11 командой:

$ brew cask install adoptopenjdk11

Вводим:

Ответ должен выглядеть примерно так:

openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.2+9)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.2+9, mixed mode)

IntelliJ IDEA — это интегрированная среда разработки (IDE), то есть система программных средств для создания проектов на разных языках программирования.

Сегодня это самая популярная IDE для языка Java. А ещё есть Eclipse, NetBeans и немало других, но мы рекомендуем именно IDEA, потому что даже её бесплатная версия обладает широкой функциональностью, подходит для профессиональной разработки и вообще делает Java проще в использовании.

В IDE обязательно входят:

  • текстовый редактор для написания кода (он знает синтаксис нужных языков);
  • компилятор;
  • отладчик.

IntelliJ IDEA доступна в бесплатной (Community) и платной (Ultimate) версиях. Чем они различаются, видно на скрине ниже:

Пока что нам хватит возможностей бесплатной версии.

На заметку: IntelliJ предлагает студентам и преподавателям свободный доступ к своим продуктам.

Заходим сюда и качаем версию для Windows.

Запускаем скачанный файл .exe:

Жмём Next (Далее) и выбираем путь для установки:

Снова Next, и настраиваем параметры установки:

В общем случае это:

  • 64-bit launcher — для запуска 64-разрядной версии приложения (будет создан ярлык на рабочем столе);
  • Add ”Open Folder as Project“» — позволяет открывать папки с исходниками как проекты прямо через контекстное меню;
  • .java — файлы такого типа (с таким расширением) будет открывать IDEA (по умолчанию и через контекстное меню).

Кликаем Next (Далее) и выбираем папку для ярлыков IDEA (оставляем по умолчанию):

Нажимаем Install (Установить), после чего стартует установка:

Дожидаемся её окончания и жмём Finish (Завершить):

При первом запуске принимаем пользовательское соглашение и нажимаем Continue (Продолжить):

Далее выбираем тему оформления (доступны тёмная и светлая):

Жмём Next: Default plugins и переходим к выбору устанавливаемых плагинов:

Если не знаете, что вам точно пригодится, — оставляйте всё как есть. А если, например, с Андроидом вам не работать — выключите соответствующий пункт.

Не волнуйтесь, если надобавляете лишнего или о чём-то забудете. Всё можно будет переиграть — в настройках среды.

После чего нажмите на кнопку Next: featured plugins и выберите другие нужные плагины (или оставляйте всё по умолчанию):

И наконец, нажимаем Start using IntelliJ IDEA.

Вас встретит начальный экран среды разработки (Welcome screen). Здесь можно создать новый проект, открыть или импортировать существующий, а также скачать проект из системы контроля версий:

Если вы видите такой же экран — поздравляю, установка и настройка прошли успешно! Приятного обучения!

Здесь всё даже легче, чем в Windows. Для начала качаем версию для macOS отсюда (о различии между редакциями Community и Ultimate читайте выше — в пункте про установку на Windows):

Открываем скачанный файл .dmg:

Копируем файл в «Программы»:

Читаем предупреждение ОС и жмём «Открыть»:

Принимаем пользовательское соглашение и жмём кнопку Continue (Продолжить):

Теперь приложением можно пользоваться. Приятного обучения!

Для установки IntelliJ IDEA открываем Центр приложений Ubuntu:

Вводим в поиск слово «Intellij» (без кавычек). Нам нужна IDEA Community (о различии между редакциями Community и Ultimate читайте выше — в пункте про установку на Windows):

Выбираем версию и нажимаем кнопку Install (Установить):
