       // Sets the value of the property "name" to "Yoda"
       property("name").ofType(String.class).in(person).set("Yoda");
    
       // Retrieves the value of the static property "count"
       int count = staticField("count").ofType(int.class).in(Person.class).get();
    
       // Sets the value of the static property "count" to 3
       property("count").ofType(int.class).in(Person.class).set(3);
