在Java中的Enum对象中存储字符串

我有这个枚举类别，一个问题类，一个存储问题，选项，类别等的数据库。问题类具有其getter（）和setter（）我的问题是如何存储来自Category类型的数据库中的字符串类型数据？rs.getString（“ Cateogory”）返回一个字符串，但我想将此字符串存储在obj类型的类别中。我该怎么办？

public enum Category {
Geography,History,GK,Science;

}

public class Question  {
private int srno;
private String question;
private String option1;
private String option2;
private String option3;
private String option4;
private String correctAns;
private Category Category;
private Complexity complexity;

public Question() {
}

Class X{
    ResultSet rs=null;
    Statement stmt=null;
    List<Question> quesList=new ArrayList<Question>();
    Question q=new Question();
    Category c=null;
    // some code here .....
    while(rs.next())
    {
               q.setQuestion(rs.getString("Question"));
               q.setOption1(rs.getString("optionA"));
               q.setOption2(rs.getString("optionB"));
               q.setOption3(rs.getString("optionC"));
               q.setOption4(rs.getString("OptionD"));
               // But how do i store a Category type?
               quesList.add(q);
    }
}
