Where is Java JDK installed on Windows 10?

Java is a popular programming language and platform that is widely used for developing a variety of applications, including Android apps, web applications, and desktop applications. Java Development Kit (JDK) is a software development kit that provides the tools and libraries needed to develop Java applications. In this article, we will explore where Java JDK is installed on Windows 10.

Default Installation Location

When you install Java JDK on Windows 10, it is typically installed in the following default location:

C:Program FilesJavajdk-version-number

Where jdk-version-number is the version number of the JDK you installed. For example, if you installed JDK 20.0.1, the default installation location would be:

C:Program FilesJavajdk-20.0.1

Environment Variables

In addition to the default installation location, you also need to set environment variables to point to the JDK installation directory. This allows you to use the JDK tools and libraries from the command line and from within your Java applications.

To set the environment variables, follow these steps:

1. Right-click on the Start button and select System.
2. Click on Advanced system settings.
3. Click on Environment Variables.
4. Under System Variables, scroll down and find the Path variable, then click Edit.
5. Click New and enter the path to the JDK installation directory, for example: C:Program FilesJavajdk-20.0.1bin
6. Click OK to close all the windows.

Checking the Installation

To check if Java JDK is installed and where it is installed, you can follow these steps:

1. Open the Command Prompt or PowerShell.
2. Type java -version and press Enter.
3. If Java JDK is installed, you should see the version number displayed.

Additional Tips

Here are some additional tips to keep in mind:

• Multiple JDK Versions: You can install multiple versions of Java JDK on your system, each with its own installation directory. This can be useful if you need to develop applications that require different versions of the JDK.
• JDK Home: The JDK_HOME environment variable points to the root directory of the JDK installation. You can use this variable to specify the JDK installation directory in your Java applications.
• Java Runtime Environment (JRE): The JRE is a subset of the JDK that provides the runtime environment for Java applications. The JRE is typically installed in the following location: C:Program FilesJavajre-version-number

Conclusion

In conclusion, Java JDK is installed in the C:Program FilesJavajdk-version-number directory on Windows 10. You can set environment variables to point to the JDK installation directory and use the JDK tools and libraries from the command line and from within your Java applications. By following these steps, you can successfully install and configure Java JDK on your Windows 10 system.
