Java统计数据库表中记录数

public static int count(String txyl_table) {// 获取用户数量
    int i = 0;// Store_Information
    Connection con = DB.getConnnection();
    try {
        Statement stmt = con.createStatement();
        ResultSet rset = stmt.executeQuery("select count(*)as totalCount from "+ txyl_table);
        if(rset.next()) {
           i=rset .getInt("totalCount");
        }
    } catch (Exception e) {
        System.err.println("你确定你没有输错表明么？？？");
         e.printStackTrace();
    } finally {
        DB.closeConn(con);
    }
    System.out.println(i);
    return i;
}
