Invoking all setters within a class using reflection

Question

Answer 1

I think you could use a library, the Apache Commons BeanUtils. If you have a map that contains field and value pairs, the class PropertyUtils can help you:

Person person = new Person();
for(Map.Entry entry : map.entrySet())
    PropertyUtils.setProperty(person, entry.getKey(), entry.getValue());
