AlmaLinxu + javac
I neglected to show how to install and configure the Java SDK on my earlier post without relying on including the $JAVA_HOME in the $PATH. This post shows how to install the Java and Java SDK on Alma Linux without layering it with the $JAVA_HOME environment variable.
You install the Java runtime and development kit with the following command:
sudo dnf install -y java-17-openjdk java-17-openjdk-devel |
Then, you need to add it to the $PATH environment variable with the following syntax in your .bashrc file or environment file of your choice.
export set PATH=$PATH:/usr/lib/jvm/java-17-openjdk-17.0.8.0.7-2.el9.x86_64/bin/ |
After you source the new $PATH environment value, you can then write a file like this Hello.java file to test it.
// Define the Java program. public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } } |
You compile the Hello.java file with this syntax:
javac Hello.java |
Then, you run the compiled program with the following syntax:
java Hello |
It’ll print:
Hello World! |
