how to ckeck whether the executeQuery function select 1 row or not

Hi,

Can somebody tell me how to check if 1 row got selected

and if not ( there is no row in table for that query data) by using executeQuery function

eg. ResultSet resultSet=stmt.executeQuery(select * from emp where name = 'ray');

in case if this query does not return any row then i want to display there are no records

else i want todisplay 1 row select
