The situation is this:

a bean
public class Student {
int id
String name;
int score;
String classname;

many attributes, to Set attribute can only set up one by one,
Student sd = new Student ()
sd.setId (xx)
sd.setscore (xx)
very troublesome .. and is not universal, if the bean to add a property, as long as you have all the code in place for such an assignment would bean write sd.setXXX (xxx);
I wanted to write such a generic method, Like ResultSet, able to use ResultSet.getString (int x) or Resultset.getString (String fieldname) in such a way you can get the desired properties, such as

StudentHelper.getString ("classname" ) ... Back classname
StudentHelper.getString (1) ... return id
is to get a class all of the variables and the classes in the order defined
