How get method with List<SomeObject> as parameter using Reflection

I have 

public void setContacts(List<PersonContact> contacts) {
    this.contacts = contacts;
}

A need get this method using Reflection, I have tried

  clazz.getMethod("setContacts", ArrayList.class);

show the erro : 

java.lang.NoSuchMethodException: model.person.Person.setContacts(java.util.ArrayList)

That's correct, the method signature is 

    setContacts(List<PersonContact> contacts)

So, how can I pass correct signature in getMethod?

the parameter type is java.util.List and not java.util.ArrayList

clazz.getMethod("setContacts", List.class);

It is important that you uses the actual class because you could also have the method overloaded with an ArrayList parameter
