What is the best way to store data for this project?

Question

hey everyone,
I have been subscribed to this for a while, not sure if I have ever actually asked anything though.
I have a project on the go for myself/portfolio
It is a booking sheet, where by I have a GUI that has a diary system of a day followed by time slots. This also has a date picker that can change the date of the booking sheet
I want to be able to store mainly strings and ints,
I need to be able to store, retrieve and on occasion change some data.
I was looking at using something called JExcelAPI but I cant get that to work at all, I asked for assistance but was refered to here.
what would be the best way to implement this data storage?

Hey everyone,
Back again,
I got this this little snippet of code working but want to ask you guys for a little bit of help on it. if thats ok?
try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     String dataSourceName = "mdbTEST";
     String dbURL = "jdbc:odbc:" + dataSourceName;
     Connection con = DriverManager.getConnection(dbURL, "","");
     // try and create a java.sql.Statement so we can run queries
     Statement s = con.createStatement();
     s.execute("create table TEST1234567 ( column_1 char(27), column_2 char(150), column_3 char(150), column_4 char(150), column_5 char(150), column_6 char(150))"); // create a table
     s.execute("insert into TEST1234567 values('"+date+"','"+a+"','"+b+"','"+c+"','"+d+"','"+e+"',)"); // insert some data into the table
     s.execute("select column_7 from TEST1234567"); // select the data from the table
     ResultSet rs = s.getResultSet(); // get any ResultSet that came from our query
     if (rs != null) // if rs == null, then there is no ResultSet to view
                while ( rs.next() ) // this will step through our data row-by-row
          /* the next line will get the first column in our current row's ResultSet
          as a String ( getString( columnNumber) ) and output it to the screen */
               System.out.println("Data from column_2: " + rs.getString(1) );
     s.execute("drop table TEST1234567");
     s.close(); // close the Statement to let the database know we're done with it
     con.close(); // close the Connection to let the database know we're done with it
catch (Exception err)
     System.out.println("ERROR: " + err);
     err.printStackTrace();
}there are more columns, but i cut this code down.
my question is:
I think I want a method with an if statement to see whether the table is created or not, if not create it, but how do I go about this? I have searched the API and google, but my brain is fried.
Also do I always have to do the try/catch and have the code of Class.forname to Statement s in all methods that want to deal with the table?
