bash：java：找不到命令（Fedora）

Question

On Fedora I installed (or at least tried to install) JDK-18. I rebooted my laptop and wanted to check if it succeeded. I used java --version , but it said bash: java: command not found .

Answer 1

Well all that I will write is subjective. It all depends upon how did you install java in Fedora. If you downloaded the jdk distribution and unzipped it to some folder. Then in your.bashrc, you need to provide the path where the binaries are available

export PATH=$PATH:/path/to/java/installation/folder/bin

You can also look at sdkman https://sdkman.io/

This is a nice tool to manage your JDK(s) regardless of Linux distribution you are using. (disclaimer: I have no affiliation with sdkman - i find this tool very helpful)
