Question

我编写了Java程序，它从xml中提取数据并提供以下输出。提取完成后，数据必须存储在SQL数据库中。请帮我在SQL数据库中添加数据，

以下输出必须存储在数据库中，

输出： -

Root element of the doc is geodata
Total no of people : 2
Address : 2344 States Drive, MA 01213, USA
Phone Number : 333-222-2222
Salary : $3000
Pension : $3000
Address : 2345 Gates Drive, PA 11213, USA
Phone Number : 444-222-2222
Salary : $3500
Pension : $3500

创建一个方法说插入（root，noOfPeople，Address，phNo，salary）并将所有想要插入数据库的数据逐个传递给参数值，以便它按行插入

数据库中的第1行将是 -

   Address : 2344 States Drive, MA 01213, USA
   Phone Number : 333-222-2222
   Salary : $3000
   Pension : $3000

数据中的第2行将是 -

Address : 2345 Gates Drive, PA 11213, USA
Phone Number : 444-222-2222
Salary : $3500
Pension : $3500

如果你不知道如何存储数据，那么在java中读取JDBC。你也可以试试 1. How to store data in Java? Database? 2. http://www.tutorialspoint.com/jdbc/jdbc-db-connections.htm 3。http://www.tutorialspoint.com/jdbc/jdbc-insert-records.htm
