What is the purpose of the choice class in Interactive Story?

The code below is as follows. I don't understand why we need it (because I'm not conceptualizing what is going on here). Any explanation will be greatly appreciated!

public class Choice { private String mText; private int mNextPage;

public Choice(String text, int nextPage) {
    mText = text;
    mNextPage = nextPage;
}

public String getText() {
    return mText;
}

public void setText(String text) {
    mText = text;
}

public int getNextPage() {
    return mNextPage;
}

public void setNextPage(int nextPage) {
    mNextPage = nextPage;
}

}

I'm curious about this too so am digging into it right now. Did you ever figure out what exactly it does?

Yeah, this class has the getters and setters for the variables above. You can set the text here then get it from another point in your code with the getText() method. It's relatively simple, just don't over think it
