Java development kit download for windows

JDK 23 is a regular update of the Java SE platform, released on September 17^th 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:

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:

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:

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.

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.

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:
