Is there a way to get types/names of an unknown db query without executing it?

import java.sql.*;
. . .
Connection conn;
. . .
PreparedStatement ps = conn.prepareStatement("SELECT * FROM foo");
ResultSetMetadata rsmd = ps.getMetaData();
int numberOfColumns = rsmd.getColumnCount();

DECLARE
  lv_stat varchar2(100) := 'select blah blah blah';
  lv_cur INTEGER;
  lv_col_cnt INTEGER;
  lv_desc DBMS_SQL.desc_tab;
BEGIN
  DBMS_SQL.parse(lv_cur,lv_stat,DBMS_SQL.NATIVE);
  DBMS_SQL.describe_columns(lv_cur,lv_col_cnt,lv_desc);
  FOR ndx in lv_desc.FIRST .. lv_desc.LAST LOOP
    DBMS_OUTPUT.PUT_LINE(lv_desc(ndx).col_name ||' '||lv_desc(ndx).col_type);
  END LOOP;
END;
