resultset as string

[neha gupta]

I have a query which has output of one single string line "My name is ---,
living in city -----, located in country ----.

After query string , I have executed the query

 Query query = QueryFactory.create(queryString);
QueryExecution qexec = QueryExecutionFactory.create(query, model) ;
ResultSet rs = qexec.execSelect() ;
I want this string to be displayed as string:
JOptionPane.showMessageDialog(null, string);

But I dont think I need while(rs.hasNext()) and convert it to string
because resultset only contain one string output at one time.
How can I display the resultset as string?
