Is the a name for practise of avoiding using programing langue types?

I try to convince coworkers to stop writing code like this (example in java):

class Person {
    Long id;
    String name;
    String surname;
}

and write code like this:

class Person {
    PersonId id;
    PersonName name;
    PersonSurname surname;
}

Basically, I want to avoid overusing Strings', Longs' and use dedicated types that correspond to a domain. This is not a new concept, methodology or practise (however you call it), so it probably already have a name. There probably are many people who have already written pros and cons of such approach, but I cannot find any, because I do not know what to look for.
