Yes, Java can run smoothly on a range of platforms. It is the simplest programming language, which you can run on Mac OS, Windows, Linux, Ubuntu, and so on.
In this tutorial, we will study how to install java on windows 10, Java installation in Windows Operating System, How to check the version of installed and Setting up Environment Variable. So let’s start.
Java has support for many platforms like Windows, Linux, Solaris, etc. These platforms have their own installation methods. In this tutorial, we will be covering the installation procedure Windows operating system for both 32-bit and 64-bit OS.
Java installation in Windows Operating System
In the Windows Operating System, both 32-bit and 64-bit Windows OS have a similar way of installing Java. The main difference comes with their installation packages.
How to check the version of Java installed on the host machine?
Today’s software applications and programs need Java to run and execute properly. This software and programs require Java to be installed on the system to properly get executed. So if you have one of these applications or software installed on your computer then you possibly might also have Java already installed on your computer.
To check whether you have Java installed on your computer, follow this simple procedure,
- On your keyboard, press Windows + R. This will open up the Run dialog box on the bottom left of the screen.
- In the textbox on the Run dialog, type cmd and then click OK. This is open to the Command Prompt (CMD) window.
- In the Command Prompt, type java -version(make sure you type it correctly) and then press Enter.
- If you see the output similar to the output given below with some Java version, then you already have Java installed on your computer and there is no need to continue with the further installation steps.
- In the other case, if your output in the Command Prompt is not similar to the output given above, then continue with the next step.
Step 1: Know the type of operating system you have
An important step to installing Java is to know the type of operating system you have on your computer. The Windows operating system comes in 32-bit and 64-bit architecture in the market. At this point, if you know the operating system type of the host machine that needs Java installation, then you can continue to the next step. If you are not aware of the system type for your operating system, continue following these steps:
- Open File Explorer that comes with your Windows operating system.
- On the left side panel, Right-click on This PC to open the context menu and then click on Properties.
- This will open up the System Properties of your computer. Now, under the System section, check out the System type of your computer.
Step 2: Download the Java Development Kit (JDK)
- Go to the official Java website and browse through the JDK packages available in the given link below.
Link: https://www.oracle.com/
- After opening the given link, scroll down the page and click on the appropriate download link based on the host operating system that needs Java installation.
- A pop will appear for you to accept the license agreement. You can read it just in case you want to know more about their terms and conditions. If you are satisfied with the Terms and Conditions/License Agreement, then select the checkbox accepting the license agreement and click on the Download button (in green).
In case you don’t have an Oracle account, follow this link to create a new account. Link: (https://profile.oracle.com/)
- Once the Java installer is downloaded, open the installer package, and follow the installation wizard. You can configure the installation to change the installation path if needed. But it is recommended to let the default installation settings during installation.
After completion of the installation, just repeat the part ‘How to check the version of Java installed on your computer?’ to make sure everything went well.
Setting up Environment Variable for Java
Windows operating system uses Environment variables to access externally installed applications and programs. Environment variables are Key-Value pairs. Each Key represents one or more resources or applications or programs. These Environment Variables are mostly used by the operating system and other applications to access or use an external application or program.
In this section of the tutorial, we will set environment variables in Windows operating system so that the host system can have access to Java and its libraries. By setting up Environment Variables for Java, we enable Java to be used as a global command in the host machine.
Setting up the Environment Variables for Java in Windows 10?
- Locate the Java installation on your PC. By default, Java can be located in one of these directories:
C:/Program Files/Java/jdk-<version>/bin – For 64-bit OS
C:/Program Files (x86)/Java/jdk-<version>/bin – For 32-bit OS
You need to copy the location of the bin folder in the directory where Java is installed. You can make sure you have selected the right folder if it has both Java and javac.
- Click on the Environment Variables button under the Advanced tab.
- Under the System Variables section, locate the Path variable and double-click on it.
- Click on New and paste the location of the bin folder of the Java installation from step 1 and click on OK.
- You have successfully set the Java environment variable.
The object-oriented programming language Java offers advantages such as platform independence, security and multithreading, which you can also use in Windows 10. But, first, clarify whether you need a 32-bit or 64-bit version before installing Java on Windows 10.
Java is one of the most widely used Internet programming languages and is also suitable for users who are just learning programming-learning. In Windows it was already supported since the update 51 for Windows 8. Those who want to use Java on Windows 10 or also on Linux and macOS can download the installation files free of charge from the website of the Java developer Oracle Corporation.
Attention! The Edge browser does not support Java plug-ins, so Java cannot be used in Edge. Browser like Firefox or Safari again require a Java plugin or applet. In addition, you need to clarify whether you need Java as 32-bit or 64-bit for Windows, depending on your operating system.
If you want to get the most out of Java, you should get an overview of the most important Java commands and Java operators. Particularly handy is the comprehensive software development kit (SDK), which includes the Java Development Kit with a collection of utilities, tools and runtime environments.
Is Java already installed?
Before installing Java, you can check if Java is already on your system. This way you save the installation steps and can use Java directly. You can find out whether Java is already present via the display for installed software on the Windows system. To do this, enter “Control Panel” in the Windows search line and click on the corresponding result. Then go to “Programs” > “Programs and Features”. There you will find all installed programs listed alphabetically. If Java is installed, there is also an entry for Java.
You can check whether you need the 64-bit version of Java by pressing the Windows-Shortcut [Windows] + [i] for the Windows settings. In the opened settings you get to the “Device specifications” via “System” > “About”. If it says “64-bit” in the “System Type” section, you can use both the 32-bit and 64-bit versions.
Java has stopped supporting 32-bit systems, so Java only runs on 64-bit operating systems. However, both the 32-bit and 64-bit versions will work fine in these. Therefore, both Java versions are recommended if you alternate between using a 32-bit and 64-bit browser. On the other hand, Oracle Corporation advises using a standard 32-bit browser and the 32-bit Java version for best performance.
Download Java for users
Follow the steps below to install the latest version of Java in Windows 10:
Step 1: In your default browser, open the Java download page from Oracle Corporation java.com. Here you will find the appropriate latest Java version for operating systems such as Windows, macOS, Linux or Solaris.
Step 2: Download the latest Java version for the applicable operating system.
Step 3: Decide whether you want to perform an online download using an executable IFTW file (“Install from the Web”) or as an offline download using an executable file. In the Java setup prompt, confirm that you really want to install Java. By doing so, you automatically agree to Java’s license agreement.
Step 4: With the Java download, you also get the Java Runtime Environment (JRE), which allows you to use Java plug-ins and run Java applets in a compatible browser. The JRE also includes the Java Virtual Machine, the Java main classes and Java libraries.
Have you upgraded your Windows operating system to Windows 11 and wondered if Java can be used with it? Then don’t worry: You can easily install Java on Windows 11.
Download Java: For developers
If you would like to use Java not only in the browser, but also as a programming language including tools, you can download the Java Development Kit (JDK) from the Java website. The JDK includes helpful tools and programs such as a Java editor, a compiler and interpreter, a debugger as well as documentation tools, API classes, archivers, signing programs, tools for applets and performance monitoring, and a web service importer. The Java Runtime Environment (JRE) is also included in the JDK.
Follow these steps to install Java in Windows 10 as a developer:
Step 1: Open the Developer website of Java. On the landing page, you will already see the download button for the current version of Java (as of 2022: Java 18). If you want to use the Java Development Kit, go to the Oracle website for Java downloads.
Step 2: Choose between options like “x64 Compressed Archive” as ZIP file, “x64 Installer” as EXE file or “x64 MSI Installer” as MSI file for the download. Confirm the Oracle Java license agreement for the download.
Step 3: Open the downloaded file and extract the ZIP files first or double-click on the installation file. The installation wizard will now guide you through the simple installation steps. The installation itself takes only a few minutes.

Для разработки программ на Java нам потребуется специальный комплект для разработки JDK
(Java Development Kit). JDK включает ряд программ и утилит, которые позволяют компилировать, запускать программы на Java,
а также выполнять ряд других функций.
JDK от Oracle для Windows (x64), Linux (x64, ARM64) и MacOS (x64, ARM64) доступны по адресу https://www.oracle.com/java/technologies/downloads/
OpenJDK для Windows (x64), Linux (x64, ARM64) и MacOS (x64, ARM64) доступны по адресу https://jdk.java.net/21/
OpenJDK предоставляет только архивы, Oracle также предоставляет установочные пакеты. Рассмотрим установку JDK для различных систем.
Установка на Windows
Установка с помощью установщика
Наиболее распространенный вариант установки JDK на Windows — это применение установщика с официального сайта Oracle. В частности, перейдем на страницу:
https://www.oracle.com/java/technologies/downloads/#jdk22-windows
Нажмем на кнопку Next. На следующем экране необходимо указать, в какую папку будет производиться установка:
Оставим выбор папки по умолчанию и нажмем на Next для выполнения установки.
После завершения установки JDK мы увидим вот такое окно:
При установке JDK все файлы по умолчанию помещаются в каталог C:\Program Files\Java\jdk-[номер_версии] (если при установке не было изменено расположение).
Так, если мы откроем в нем подкаталог bin, то мы сможем увидеть в нем ряд утилит.
Нас прежде всего интересует утилита компилятора javac и утилита java.exe. javac компилирует код на языке Java в бинарный файл, а
java.exe позволяет запускать скомпилированный файл:
Установка через пакетный менеджер
Через пакетный менеджер winget также можно установить OpenJDK от Microsoft. Для этого в командной строке/PowerShell надо выполнить команду:
winget install Microsoft.OpenJDK.21
В данном случае устанавливается 21-версия JDK.
Установка на Linux
Если мы используем JDK от Oracle, то в данном случае нам доступен ряд вариантов установки. В частности, перейдем на страницу:
https://www.oracle.com/java/technologies/downloads/#jdk22-linux
-
ARM64 Compressed Archive: архив для систем на архитектуре ARM64
-
ARM64 RPM Package: RPM-пакет для систем на архитектуре ARM64, которые для управления пакетами применяют RPM (например, Fedora, Suse и т.д.)
-
x64 Compressed Archive: архив для систем на архитектуре Intel x86-64
-
x64 Debian Package: Debian-пакет для систем на архитектуре Intel x86-64 (например, Ubuntu, Debian и т.д.)
-
x64 RPM Package: RPM-пакет для систем на архитектуре Intel x86-64, которые для управления пакетами применяют RPM (например, Fedora, Suse и т.д.)
Если наша операционная система Ubuntu (на платформе Intel x86-64), то выберем пункт x64 Debian Package, и нам загрузится debian-пакет (в моем случае файл «jdk-22_linux-x64_bin.deb»).
Для его установки выполним команду
sudo dpkg -i jdk-22_linux-x64_bin.deb
Если у нас операционная система, которая для управления пакетами применяет RPM, например, Fedora, Suse и др, на платформе Intel x86-64,
то необходимо выбрать пункт x64 RPM Package. И затем установить загруженный пакет командой
sudo rpm -ivh jdk-22_linux-x64_bin.rpm
Если у нас ОС Fedora, Suse и др, на платформе ARM64, то необходимо выбрать пункт ARM64 RPM Package. И затем установить загруженный пакет командой
sudo rpm -ivh jdk-22_linux-aarch64_bin.rpm
Также для различных операционных систем в репозиториях могут быть доступны пакеты JDK для установки. Например, установка с помощью пакетного менеджера snap:
sudo snap install openjdk
Установка с помощью пакетного менеджера apt:
sudo apt install default-jdk
Установка определенной версии JDK с помощью пакетного менеджера apt:
sudo apt install openjdk-22-jdk-headless
В случае с установкой архивов все идентично для всех основных систем на базе Linux — загружается архив, распаковывается в определенное место. Затем в переменные среды добавляется путь к папке bin распакованного архива.
Установка Java на MacOS
Для установки Java на MacOS перейдем на страницу загрузок на сайте Oracle по адресу https://www.oracle.com/java/technologies/downloads/#jdk21-mac:
Здесь нам доступно 4 варианта пакетов:
-
ARM64 Compressed Archive: архивный пакет для MacOS на ARM
-
ARM64 DMG Installer: установщик для MacOS на архитектуре ARM
-
x64 Compressed Archive: архивный пакет для MacOS на архитектуре Intel x86-64
-
x64 DMG Installer: установщик для MacOS на архитектуре Intel x86-64
Загрузим и после загрузки запустим пакет установщика. Вначале нам отобразится приветственное окно.
Далее на всех последующих шагах оставим все опции по умолчанию. И после установки нам отобразится окно об ее успешном окончании:
Проверка установки
После установки Java перейдем к командной строке/терминалу и для проверки версии введем команду
java -version
Консоль нам должна в ответ ввести номер только что установленной версии JDK (в моем случае 22-й версии):
java 22 2024-03-19 Java(TM) SE Runtime Environment (build 22+36-2370) Java HotSpot(TM) 64-Bit Server VM (build 22+36-2370, mixed mode, sharing)
Итак, после установки JDK создадим первую программу на Java.
