Download and Install Java Development Kit (JDK) on Windows, Mac, and Linux (original) (raw)

**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.

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.

Java JDK Download

**The JDK can be installed on the following Platforms:

Microsoft Windows
Linux
macOS

Download JDK (Java Development Kit)

We need to download the JDK first, find the steps below to get started:

Step 1: Visit the Official Website

Go to the Official JDK website to download the file.

jdk

Oracle Official Website

Since JDK is an open-source, so you can get it from OpenJDK in a few clicks.

jdk-alt2

OpenJDK

Step 2: Select the Appropriate Version

As of 2025, the latest stable versions are **JDK 23 (SE) and **JDK 21 (LTS). Select the compatible version as per your operating system (Windows, Mac or Linux)

jdk-3

JDK Latest Version - Download

Step 3: License and Agreement

Go through all the License and Agreement before downloading (from Oracle website), it will not ask if you'll download it from OpenJDK website.

Install JDK on Windows

Follow the below steps to install JDK on Windows environment _i.e.**Windows 7, Windows 8, Windows 8.1, Windows 10, and **Windows 11.

**Step 1: Run the Java Development Kit (JDK) Installer

Locate the downloaded .exe file ****(e.g. jdk-23-windows-x64_bin.exe)** and make the double click to begin the Installation process. Follow the installation wizard prompts to complete the installation process.

jdk-win1

JDK Installer for Windows

**Step 2: Setup the Environment Variables

Once the installation gets completed, you need to configure environment variables to notify the system about the directory in which the **JDK files are located.

Proceed to **C:\Program Files\Java\jdk-{YOUR_JDK_VERSION}**\bin (replace {-} with your JDK version)

Step 2 - Locating JDK File

Program Files

**Step 2.1: To set the Environment Variables, you need to search Environment Variables in the Task Bar and click on **“Edit the system environment variables”.

Step 2 - Configuring Environment Variables

System Properties

**Step 2.2: Under the **Advanced section, Click on ****"Environment Variables"**.

Step 2 - Setting Environment Variable

Environment Variables

**Step 2.3: Under **System variables, select the ****"Path"** variable and click on ****"Edit"**. Click on ****"New"** then paste the Path Address i.e. **C:\Program Files\Java\jdk-{YOUR_JDK_VERSION}**\bin. Click on ****"OK"**.

Step 2 - Setting Path Environment Variable

Path

**Step 2.4: Now, in the **Environment Variables dialogue, under **System variables, click on ****"New"** and then under **Variable name: JAVA_HOME and **Variable value: paste address i.e.

**C:\Program Files\Java\jdk-{YOUR_JDK_VERSION}. Click on **OK => OK => OK.

Step 2 - Setting JAVA_HOME Environment Variable

System Properties

**Step 3: Check the Java Version

Open Command Prompt and enter the following commands:

java -version

javac -version

Command Prompt

Install JDK on Linux

Follow the steps below to install the Java software Development Kit on a Linux environment. These instructions are applicable to various Linux distributions such as **Ubuntu, **Fedora, and **CentOS.

**Note: We have used Kali Linux distributions here.

Step 1: Install Oracle Java Development Kit (JDK)

To install the downloaded JDK File using terminal, Open terminal and change your directory to downloads by using the command:

$ cd downloads

To list files and packages present in the directory, Type

$ ls

Step 1 - Change Directory to Downloads for JDK

Root Kali

**Step 1.1: Now we use **Debian Package Manager to configure our downloaded file for installation by typing

$ sudo dpkg -i jdk-{YOUR_JDK_VERSION} (replace {-} with your version)

Enter your password as we have run an elevated prompt, i.e. the **sudo or **superuser do command, which is a quick way to grant specific users permission to perform specific system commands at the system's root (most powerful) level.

Step 1 - Extract Package for Installing JDK

Kali Linux

**Step 1.2: Now, Type the following commands to proceed with the installation

$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-{YOUR_JDK_VERSION}/bin/java 1

$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk-{YOUR_JDK_VERSION}/bin/javac 1

**Step 2: Check the Java Version

Open the **terminal and enter the following commands

$ java --version

$ javac --version

Step 2 - Checking Java Version

sudo

**Step 3: Configure JAVA_HOME Environment Variable

After the installation is complete, we have to configure environment variables to notify the system about the directory in which jdk files are located. To find the Location of the JDK Files, run this command and copy the File Location.

$ sudo update-alternatives --config java

In order to set the environment variable, you need to edit the environment file using the following command:

$ sudo gedit /etc/environment

**Step 3.1: Proceed to add **JAVA_HOME=” /usr/lib/jvm/jdk-{YOUR_JDK_VERSION}**”

Proceed to save and close the file.

Step 3 - Configuring JAVA_HOME

environment

**Step 3.2: Now we have to refresh the environment file by using this command:

$ SOURCE /etc/environment

And echo the JAVA_HOME Path

$ echo $JAVA_HOME

Install JDK on macOS

**Step 2: Configure Environment Variables

Open the terminal and pass the following commands. To find the Location of the JAVA_HOME, run this command:

$ /usr/libexec/java_home -v{YOUR_VERSION}

Step 2 - Configuring Environment Variables

Configure

**Step 2.1: We have to set this output as our JAVA_HOME Environment Variable. You can use any command or code editor to edit the file, here we are using VS Code

$ code ~/. bash_profile

Step 2 - Configuring JAVA_HOME

Terminal

**Step 2.2: At the very bottom, we have to export the path we obtained earlier i.e.

$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-{YOUR_VERSION}.jdk/Contents/Home

Step 2 - Configured JAVA_HOME Path

bash

**Step 2.3: Now we have to refresh the environment file by using this command:

$ source ~/.bash_profile

And echo the JAVA_HOME variable

$ echo $JAVA_HOME

Step 2 - Refreshed JAVA_HOME Environment Variable

Java HOME

**Step 3: Verify the Java Version

In the **terminal, enter the following commands

$ java -version

$ javac -version

Step 3 - Checking Java Version

javac
