Create a main method for the class DatabaseManager that prints out the last name and age of all the people who are under 30 in the database.

{
// c r e a t e the databas e manager f o r an Access databas e
DatabaseManager dbManager =
new DatabaseManager ( "sun . jdbc . odbc . JdbcOdbcDriver " ,
" jdbc : odbc : per son " ) ;
// test a query
dbManager.testQuery ( " S e l e c t LastName , Age From Person " +
"Where Age < 30" , 2 ) ;
}
```
