Hello World Program

Create a new Project

You can use the karina CLI to create a new project with the following command:

karina new example

Your project folder should now look like this:

example/
└── src/
    └── main.krna

The main.krna file should contain the following code:

import java::java.lang.System

fn main(args: Array<string>) {
    System.out.println("Hello World!")
}

You can change the current directory into the new project folder:

cd example

Than compile the program with the following command:

karina build src

this will create a build folder with the compiled program.

Run the Program

To run the program, use the java command to execute the build.jar file.

java -jar build/build.jar

You should see the following output:

Hello World!
