Using generic getter methods in Java SE 7

So far in this chapter, I have been describing how to retrieve data from ResultSet using specifically-typed Getter methods. For example, in this version of my project, GenericGetters, in my Tours class, I have calls to the methods getInt, getString, and getDouble, and I'm selecting the method to match the data type of the column. So, the tour ID is an integer, so I call getInt, tour name is a string column, so I'll call getString, and so on. In Java 7, there is a new approach, a Generic Getter method called getObject that you can use on every column of ResultSet, and you explicitly data type the return value using a different syntax.

Now again, this new Generic Getter method is only available in Java 7. So if you're using an older version of Java, you should stick with these explicitly data typed method calls. But if you are working with Java 7 and therefore JDBC 4.1, this new approach is just another option, another tool in your toolkit. I'll start this exercise by re-factoring th...
