I have a couple of doubts of this particular case, cause this exercise has two classes, so I need to create an analyzer for RaceTrack ? I would like your tips @sanderploegsma to know if I'm in the correct path

Overall this looks good!

I have a couple of doubts of this particular case, cause this exercise has two classes, so I need to create an analyzer for RaceTrack ?

No there is no need to create separate analyzers for each class. The analyzer is invoked with a list of CompilationUnits, which contain all the classes in the solution. Each CompilationUnit corresponds to a Java file, FYI.

If your analyzer needs to have some logic specific to a single class of a multi-class solution, there are multiple ways of achieving this. Here's one from the top of my head:

public class NeedForSpeedAnalyzer implements Analyzer {
    @Override
    public void analyze(Solution solution, OutputCollector output) {
        var needForSpeedClassAnalyzer = new NeedForSpeedClassAnalyzer();
        var raceTrackClassAnalyzer = new RaceTrackClassAnalyzer();

        for (var compilationUnit : solution.getCompilationUnits()) {
            compilationUnit.getClassByName("NeedForSpeed").ifPresent(c -> c.accept(needForSpeedClassAnalyzer, output));
            compilationUnit.getClassByName("RaceTrack").ifPresent(c -> c.accept(raceTrackClassAnalyzer, output));
        }
    }
}

class NeedForSpeedClassAnalyzer extends VoidVisitorAdapter<OutputCollector> {
    @Override
    public void visit(MethodDeclaration node, OutputCollector output) {
        // Only called for methods in the NeedForSpeed class
    }
}

class RaceTrackClassAnalyzer extends VoidVisitorAdapter<OutputCollector> {
    @Override
    public void visit(MethodDeclaration node, OutputCollector output) {
        // Only called for methods in the RaceTrack class
    }
}

Hope that helps!
