I have a program that gives the user a survey and saves the data gathered to different binary files for different political parties. I have this class:

public class MyClass {

    //PoliticaParty is an enum for political parties (Republican, Democrat, and Libertarian

        public PoliticalParty party; 
    private final String filePath;
    private List<byte[]> previousSurveyData;
    
    public ProbabilityManager(PoliticalParty party) {
        this.party = party;
        filePath = "data/" + party.name().toLowerCase() + ".bin";
        previousSurveyData = SurveyFilesIO.readFromBinaryFile(filePath);
        //The filepath is passed to the above method from another class I have to read the information.
    }

Whenever I run this, I get a FileNotFoundException. I would really appreciate some help.
Thanks!

I’m writing this in Eclipse, so I was trying to see if I need to have a resources folder in there, but I’m not sure about that. I’m going to be sending the finished project to someone, so I just don’t want to run into any issues. I have mostly worked with text files, so this is unfamiliar territory.
