How to know the jdk version on my machine?
First uninstall all the versions of Java, install Jdk 8. Open new command prompt and type java -version.
If your JDK is on your path you should be able to tell by just running ‘javac -version’. From the error you described it sounds like you’re on Windows, so if the first command fails try executing (with the quotes) the following: «%JAVA_HOME%\bin\javac -version»
@AlexBroadwin your method worked for me. But i’ve installed 8th version and in cmd «1.8.0_221» is coming. What does that mean?
4 Answers 4
you might need to add path in environment variables which you can find in Control Panel open the Jdk where you installed and add until /bin in the path in environment variables.
Add until /bin in path variable in System Variables which is residing in Environment Variables.
Then do java -version which might show up.
If still problem persists, try restarting your pc and see.
Your method worked for me. But i’ve installed jdk version 8 and in cmd java version «1.8.0_221» is coming. What does that mean?
you are good, you have installed Java 8 and the _221 is just the update release(They keep on adding some features or there will be minor updates), for more info you can refer by clicking here oracle.com/technetwork/java/javase/…
-version is useless: C:\Windows\system32>java -version java version «1.8.0_281» Java(TM) SE Runtime Environment (build 1.8.0_281-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)
You need to update your Windows path to include your %JAVA_HOME%\bin directory. %JAVA_HOME% is the directory that you installed Java into and is also an environment variable that you need to configure for command line execution of your applications. You can edit both of these in the Windows control panel and you should restart.
When you run java -version you will see the internal version number. This is explained here: https://en.wikipedia.org/wiki/Java_version_history.
Basically, you can ignore the 1. when reading version number. The _xxx is a reference to the most recent patch or build release.
java version vs jdk versions could be different ? Seems useless or confusing at best ! JDK, JSE, it’s all a bit bloody mess
On Windows 10, this required mapping the environment variable for JAVA_HOME to the JDK installation directory. Use these steps:
- Run the installer for the JDK. (available for windows here: https://www.oracle.com/java/technologies/downloads/#jdk17-windows)
- windows key -> Environment Variables , select the only result
- In the System Properties window that opened, select Environment Variables
- Select new button under the User variables section
- Variable name: JAVA_HOME , Variable Value:
- ok all open menus
- Close any open cmd prompt windows
- open a new cmd window and type echo %JAVA_HOME% It should print the installation path for the JDK.
To get your jdk location in Windows, run this at a command prompt:
This lists any and all locations of java.exe, including from your JAVA_HOME. For example, the 3rd line here reflects my JAVA_HOME location, where I’m pointing to JDK 8:
C:\Users\me> where java C:\Program Files\Common Files\Oracle\Java\javapath\java.exe C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe C:\Program Files\Java\jdk1.8.0_202\bin\java.exe Note for comparison that java -version does not reflect my JAVA_HOME location and in fact shows java version 11 instead of 8:
C:\Users\me> java -version java version "11.0.15" 2022-04-19 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.15+8-LTS-149) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.15+8-LTS-149, mixed mode) This is confusing because my Java compiles (e.g., via mvn) use JDK 8 since that’s what my JAVA_HOME is pointing to. (I’m not even sure where the version 11 it found came from; possibly from when I installed maven.)
Determining the difference between the JRE and JDK you’re running has never been straightforward. Seems like java -version used to be a way to do this, but no longer.
Adding to the complexity, you can also supposedly get your Java version info from Control Panel > Programs > Java > About. For me, that shows Version 8. That’s despite java -version showing version 11.0.15. And it doesn’t change even if I point my JAVA_HOME to JDK 11.
Note that this answer is also helpful. In my case, that helped me determine that I have java.exe and javac.exe at C:\Program Files (x86)\Common Files\Oracle\Java\javapath and C:\Program Files\Common Files\Oracle\Java\javapath . Depending on which one I have listed first in my Path variable, I get different results when i run java -version or java —version . The former seems to work when Java 8 is listed first; the latter when Java 11 is first.
How to Check Java Version on Mac or Windows
Java runs many of the applications that we use daily. Many applications cannot run on older versions of Java. Hence, it is essential to know which version is installed on your system.
In this tutorial, learn how to check the Java version on your Mac or Windows system.
- A system running macOS or Windows
- Access to the command-line/terminal window
- A version of Java installed
Check Java Version on Mac
You can find the version of Java on macOS by:
- using the GUI (Mac’s System Preferences)
- prompting for the version in the terminal window

2. Type terminal in the search bar and open it by clicking on the icon in the search results.
3. Once in the command line, run the command: java -version . The output should display the Java version installed on your MacOS.
To check the version of the primary Java compiler – javac (pronounced “java-see”) use the command:
Note: If you have a Linux system, refer to How To Check Java Version Installed On Linux.
Check Java Version on Windows
To check the Java version on a Windows computer, you can use:
Option 1: Check Java Version on Windows Using GUI
To find the Java version on your Windows without opening a terminal window, use the Control Panel.
