Connecting a Table with Java and be able to add and delete users in the table

here is some code that will work for you:
Just change the word database to the path of your database:
(ie. C:/data/database)
change the password to your password (only nessecary if the DB is password protected;

Modify the query to reflect the query you want.
This will display you the users in the DB
try{
                        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //load the Jdbc driver
                        Connection con1 = DriverManager.getConnection("jdbc:odbc:Driver={MicroSoft Access Driver (*.mdb)};DBQ=Database","dba","sql"); //get a connection
                        Statement stmt = con1.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
 String query ="select f_name,l_name from users";
                        ResultSet rs1 = stmt.executeQuery(query); //execute query
                        while(rs1.next()){
                        System.out.println( rs1.getString("f_name")+" "rs1.getString("l_name")+" is is the database");
                                         
                                               
                                               
                        }


To insert records use this query :

String deletequery="insert into users (f_name, l_name) values ("'+firstname+"','"+lastname+"')";
then call:
 stmt.executeQuery(query); //execute query



where firstname and lastname are strings containing the new names to insert.

to delete from database use this query:

String query ="delete from users where l_name='"+lastname+"' and f_name ='"+firstname;

then call:
stmt.executeQuery(query); //execute query


where firstname and lastname are strings containing the names to delete.

obviously you will need a application to insert this code into. that will dictate how users actually interact.

A suggestion would by an application that displays all records in database in a combobox, then have to 2 textboxes, and 2 buttons. one button would delete the record associated with the name currently selected in the combo box. the other button would insert the text in the text areas to the database.
just a suggestion though... if you need more help just ask

hope it helps
