HelloWorld

Setup

Install the Java 17 JDK

The files for each exercise will be submitted in a single directory. For example, the directory for this exercise will be HelloWorld, and the path to the file will be HelloWorld/HelloWorld.java.

You will need to compile your code if you intend to test it:

javac *.java -d build

Then run the following command :

java -cp build ExerciseRunner

You can use any IDE or text editor, though IDEA IntelliJ or JetBrains are specially dedicated and recommended.

To edit your code, you can use any IDE or text editor, though IDEA IntelliJ or JetBrains are specially dedicated and recommended.

On Gitea, create a repository named ((ROOT)). Each of your exercises will have its own directory, with a name matching the exercise. That directory will contain all of the files for that exercise.

Instructions

Create a file HelloWorld.java in a directory named HelloWorld.

Write a function helloWorld that returns the string 'Hello World !'.

Expected Functions

public class HelloWorld {
    public static String helloWorld() {
        // your code here
    }
}

Usage

Here is a possible ExerciseRunner.java to test your function :

public class ExerciseRunner {
    public static void main(String[] args) {
        System.out.println(HelloWorld.helloWorld());
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner
Hello World !
$
