Using reflection to know fields and the relative values

I'm trying to use reflection to know fields and relative values of a Class (MyClass).

So far I did this, but this allow me to know just the fields of a "standard" Class, not a class filled with values by me:

MyClass filledMyclass = // I put here an object got from the DB with Hibernate.
I want to get the values got from the DB ///////////////

Class <?> class = MyClass.class;        
Field [] fields = class.getClass().getDeclaredFields(); 
for(Field singleField: fields ){
    System.out.println(singleField.getName());              
}

How can I get the values of the object filledMyclass, that is filled by making a query?

I tried some code (that I didn't post here), but I didn't get what I wanted.
