Java delivers thousands of performance, stability, and security updates that is the reason why java is widely used and has a larger community base worldwide.

Installation Java SE 17 on Fedora 35

1. Run sytem updates

Before you begin any install make sure you run system updates to make your repositories up to date.

$ sudo dnf update -y

2. Installing java 17

Installing java 17 we need to get the installation package from the Oracle download pages. Use the following link to make the download easier and to get the latest version.

$ wget

If you get an error that wget is not installed, you can run the installation with the following command

$ sudo dnf install wget -y

Run the installer again this time it will go through successfully.

Check the downloaded file before extracting it

$ ls 

Move ahead and extract the contents into your home directory.

$ tar -xzf openjdk-17.0.1_linux-x64_bin.tar.gz

We need to move the contents to the /opt directory

$ sudo mv jdk-17.0.1/ /opt

You can do an ls again to verify that indeed you have moved jdk17 to the opt directory.

Let’s now set our java home directory so that every time you run java application, it knows where to run from. To do that we can do the following;

Open the ~/.bashrc file and add the following

$ sudo nano ~/.bashrc

Add the following contents to the bashrc file

export JAVA_HOME=/opt/jdk-17.0.1
export PATH=$PATH:$JAVA_HOME/bin

Save and exit the nano.

Run source ~/.bashrc so that changes to bashrc file can take effect.

$ source ~/.bashrc

Now we can check the version of the installed java with the following command;

$ java --version
openjdk 17.0.1 2021-10-19
OpenJDK Runtime Environment (build 17.0.1+12-39)
OpenJDK 64-Bit Server VM (build 17.0.1+12-39, mixed mode, sharing)

Test java 17 program

Let’s test if Java is working correctly. To do that we are going to run our first hello world program

$ sudo nano

Add the following to your

public class hello {
    public static void main(String[] args) {
        System.out.println("Hello, World! from Nextgentips"); 

You need to compile the java programs in order to show the output. To run the compilation run the following code

$ javac

If you don’t run into any errors then it’s time to run your first java program.

$ java hello
Hello, World! from Nextgentips

Setting Java 17 environment

To ensure that you cant run into problems while running java programs, we need to set JAVA_HOME environment where java will be executed. If you don’t set this environment you will encounter errors in the future. To avoid that let’s set the environment.

Let’s check where we have our java 17 with the following command.

$ which java 

You will get the path like this

So let’s set this in our /etc/environment

$ sudo nano /etc/environment 

Add the following

export JAVA_HOME=/opt/jdk-17.0.1/bin/java

Save and exit

To apply the changes using the following command

$ source /etc/environment

To check if the environment path is correct use the following command

$ echo $JAVA_HOME

If you are getting empty results know that you have not applied the changes as required, go back and do source /etc/environment

From here now you will not be required to set the environment every time you install another java version.


You have successfully installed Java 17 on Fedora 35. In case of difficulty consult the documentation
