Herefor I use. I know what this error message means, but I dont know how to fix. My computer uses Java 8 :. Could anyone help me how to change the Java version of my Computer, that i could use a newer version for my compiler. Thanks a lot. You could point that to a JDK8 installation. Alternatively, as you probably installed Java 14 on purpose: locate where it sits on your disk, and ensure your Windows PATH variable points to that location.

Or just put some “wrapper” script somewhere into your PATH, and have that wrapper script call the “java 14” java. Just go to build settings and set the compiler compliance level to the jdk you are using.

If you want to use JDK 14 instead of 8, just uninstall jdk 8 and java will use jdk I hope this helped :. You can just uninstall Java 8 and reinstall java In cases, if don’t want to delete the old one or you have manually changed the PATH variable, then:. If you done right, java -version should not work right now. You don’t need to manually update anything. If you do want, follow step 1 to change PATH.

As a Java programmer, I work on various projects based on different Java versions, especially since the transition to the six-month release cycle. From time to time, I also have a piece of Java code that I want to try out on different Java versions — on the command line without having to click through the menus of my IDE. So it is helpful to be able to quickly and easily change the Java version to be used for compiling code or executing class files.

In this article, I’ll show you how to install several Java versions simultaneously in Windows and how to switch between them on the command line with short commands. Installing several Java versions at the same time is incredibly easy in Windows.

You can download and run the installer for each version, which automatically installs the versions in separate directories. Starting with the following versions, you don’t need to change the default installation directories:. Attention — you may use the following Oracle distributions only for private purposes and development:. The following version is currently an early access build. You should use it only for testing purposes:.

In most cases, the following two environment variables decide which Java version an application uses:.

These variables should always point to the same Java installation to avoid unforeseen problems due to inconsistencies. Some programs, such as Eclipse, define the Java version in a separate configuration file for Eclipse, for example, this is the entry “-vm” in the eclipse. The installers of the Java versions listed above already create various environment variables, which you need to clean up first see below. The fastest way to change the environment variables is to press the Windows key and type “env” — Windows then offers “Edit the system environment variables” as a search result:.

As the standard version, I currently use the latest release version, Java Therefore, you should make the following settings:. Attention: this only works for the default setting configured here. Finally, we come to the possibility to change the Java version quickly and easily.

Therefore I create a separate command for each Java version, called, for example, java16 , java15 , java14 , java The files are named, for example, java This script, admittedly kept very simple, inserts the bin directory of the Java version to be activated at the beginning of the Path variable, so that is where, for example, java. The path variable becomes longer with each switching.

However, since this is only the case for the currently opened command prompt, I don’t think this is a problem. The following ZIP file contains all my scripts from Java 1. You can quickly test whether the scripts work in a command line. Attention: after adding the scripts directory to the Path variable, you have to open a new command line.

At this point, the setup is complete. I hope this article was helpful for you, and I’d love to hear your comments.

I did this and now I can use command prompts to switch between versions as verified with “java -version” BUT I still cannot get my browser based interface to function correctly on the version 6. Does this method not work for browser based applications? Try creating files in some other directory say D drive and then move those files to java folder. You just need to remember that after switching java version with script and closing terminal, next terminal will open with java default version, not the one from last script run.

Really Appreciated for this post But it is only working in the command prompt. I am using gitbash here it is not working. Sven, there is a side affect in this script. As an example, I ran java8. Hi Kolton, yes I know, I couldn’t find an easy way to fix this.

But the changes are not permanent, they only apply to the current prompt. Therefore I think it is OK. Thanks for the correction! You are absolutely right. I’ve changed it in the screenshots and text. Hello everyone. First of all thanks for the script. In my case the change of jdk worked but each time a new terminal was launched the default jdk came back As a result, I modified the script so that now with each change, the jdk selected by script is ‘saved’.

You have to add the REG be careful , only in one line line as below by adapting the right path of the jdk to your configuration:. Great idea JavaMan Could you please share the correct “reg add” command? I think it will help. Thanks for the informative guide. I didn’t set it up on the Windows 10 Server but I think that when it starts as a service using Tomcat9.

I am not a Windows aficionado so I am not sure what the registry key would be and there are only about of them. But usually, Tomcat has a setenv. This has been one of the most fruitful topics I have read and implemented in a long time. This problem of working on multiple Java versions simultaneously has been haunting me for a long time. The solution provided is cute, simple and it is going to save several hours of misery for me.
