How To Sort Collections Using commons-beanutils?

Hi everybody,

Following is another simple way of sorting collections using commons-beanutils package:

Assume that we have an object as below:

public class User {
private long userId;
private String userName;
private String password;
}

And we want to sort based on userName field. We can use BeanComparator class of commons-beanutils package as below to sort the list:

ArrayList list = new ArrayList();

//...

//add User object inside the list.

//...

Collections.sort(list, new BeanComparator("userName"));

Notice that, we passed the name of the field to be sorted, as the parameter, to BeanComparator class constructor. We accomplished sorting of a collection using just one line of code:).
