Programmer - Is it better to create a new object and return it or create the new object in the return statement?

Programmer Question

For example:

public Person newPerson() {
  Person p = new Person("Bob", "Smith", 1112223333);
  return p;
}

as opposed to:

public Person newPerson() {
  return new Person("Bob", "Smith", 1112223333);
}

Is one more efficient than the other?
