Here are all the java and enum classes

        this.text = text;
        this.number = number;
        this.isHighlighted = isHighlihgted;
    }

    public void highlight() {
        this.isHighlighted = true;
    }

    public void unhighlight() {
        this.isHighlighted = false;
    }

    public void comment(String comment) {
        comments.add(comment);
    }

    @Override

        String desc = text + ", " + number + ", " + (isHighlighted ? "highlighted" : "not highlighted, Comments: ");
