Answer 1

A good approach is to use one try - finally block like this

String query = "SELECT * FROM table WHERE UNIQUEID=? AND DIR IS NOT NULL AND NAME IS NOT NULL AND PAGETYPE IS NOT NULL";
        DBConnect Database = new DBConnect();
        Connection con = null;
        PreparedStatement ps = null;
        ResultSet rs=null;
        try {
            con = Database.getcon();
            ps = con.prepareStatement(query);
            ps.setString(1, URI);
            rs=ps.executeQuery();
            if(rs.next()){
            }

            query = "SELECT COUNTCOMMENTS FROM videosinfos WHERE UNIQUEID=?";

            ps = con.prepareStatement(query); // Getting error here
            rs=ps.executeQuery();
            ps.setString(1, URI);
            rs=ps.executeQuery();
            if(rs.next()){
                comments = rs.getInt(1);
            }
        } finally {
            if(ps != null)
                ps.close();
            if(rs != null)
                rs.close();
            if(con != null)
                con.close();
        }
