To build a Java application, a Java Development Kit is necessary. It contains not just the Java Runtime Environment, but also the Java compiler as well as the Java APIs.

Java Development Kit (JDK) and Java Runtime Environment (JRE) are obviously two different things, but they often confuse users as to which one that should be used.

Simply put, if you only need to run Java applications, use JRE. If you need to develop a Java application, download and install JDK.

Features and Highlights

Java is a programming language that saw its first release back in 1996. Thanks to its “write once, run anywhere” principle in addition to the other benefits it offered, the popularity of Java quickly skyrocketed. Major browsers were in a race to take advantage of its power.

Java’s popularity at present day is no longer as high as it used to be. The number of users to use Java for new projects has been declining thanks to the availability of relatively better alternatives and some other reasons. Its main strength that made it superior in the past is no longer its unique value as other programming languages can do the same more or less.

Java is not dead, however, and probably never will as there are still too many systems rely on it. It is still widely used in enterprises.

Anyone who is interested in writing a Java application can use the JDK developed by Oracle. Appletviewer, java, javadoc, javap, jar, jarsigner, jdb, and many more tools are available in JDK. All of these things usually reside in the Program Files folder when JDK is installed on Windows operating system. You can open the folder to see everything that JDK has.

JRE also presents alongside the other tools in JDK. JRE has all the resources required, including Java Virtual Machine (JVM), to execute Java codes.

JDK installation normally runs without problem. If you run into trouble during the installation, there is usually an error message that describes the situation so that you can take the appropriate measure.

For example, an error message stating “system error during decompression” is an indication of lacking enough space to perform the decompression task.

One of the possible reasons of why JDK cannot be installed is the leftover files resulted from the previous JDK uninstallation. There might be some items that are left behind in the registry. To fix this, you should remove the items from the registry.

Java Development Kit Free Download for Windows

JDK takes up around 420 MB of space in your storage media. In Windows, the Program Files is the default location where JDK will be installed. As for the installation, it can be done by double-clicking the JDK installer or by using command-line arguments to install it silently.

The installation adds a new item in the Start Menu. The item is a shortcut to open the reference documentation in your default browser. It is an online documentation so an internet access is required in order to view the pages. You can click the link below to download Java JDK for Windows:

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:

1. Microsoft Windows
2. Linux
3. 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.

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 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)

Картинка с сайта: www.geeksforgeeks.org

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”.

Картинка с сайта: www.geeksforgeeks.org

System Properties

Step 2.2: Under the Advanced section, Click on “Environment Variables”.

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.

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

Картинка с сайта: www.geeksforgeeks.org

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.

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

Картинка с сайта: www.geeksforgeeks.org

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.

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

Follow the steps below to install the Java Development Kit (JDK) on macOS. These instructions are compatible with various versions of macOS, including Mojave, Catalina, Big Sur, Monterey, Ventura, Sonoma the latest macOS Sequoia.

Step 1: Install Oracle Java Development Kit (JDK)

Proceed to Install the JDK kit by following the bootstrapped steps:
