This repository contains a local version of Andy including exercises that can be solved and graded. To use this repository locally you have to clone it to your own machine.

To open an exercise, you have to choose a folder which corresponds to a category of an exercise. In that folder, there is a list of exercise from which you can choose, each one following the same basic structure. Inside every exercise, there is a README.md file explaining the exercise and a pom.xml file which contains the full project structure. To work on an exercise, you have to import this pom.xml file into your preferred IDE, e.g. IntelliJ or Eclipse.

Every exercise contains three folders: config, solution and src. The folders have the following functionality:

• config: contains a Configuration.java file, which is used by andy for grading your exercise. You do not have to change this, but if you want to have a different type of grading, check out the Andy repository on how to change this file.
• solution: contains a ExerciseNameTest.java file, which is a solution to the exercise. You could use this if you're stuck.
• src: contains two files, ExerciseName.java and ExerciseNameTest.java. The file without Test is the file that you need to test, the file including Test is the file where you have to write your solution.

For andy to work properly, you should not add any other files to the exercises. If you add any files, we cannot guarantee it will work correctly.

The only thing you have to do is write your tests inside the ExerciseNameTest.java file inside the src folder, not in the solution folder.

Grading an exercise goes through the command line or through a Maven plugin. For the command line you need to have Maven installed.

You have to ensure you are in the same directory the pom.xml file is in. If you are in that directory you can just run: mvn andy:run. This will output your errors, results and grades to the console.

If you have a Maven Plugin integration with your IDE, you would only have to look for the plugins under the category andy and run the andy:run plugin. This will run Andy in a new window and print the errors, results and grades there.

We use Java 17 for all the exercises and in the grading tool. We can't promise things will work in other versions (you know Java, don't you?)
