ReadWriteProperty中的R泛型类型应该如何使用？

public interface ReadWriteProperty<T, R> {
    R getValue(T obj);
    void setValue(T obj, R value);
}

public class Person {
    private String name;
    
    public String getName() {
        return name;
    }
    
    public void setName(String name) {
        this.name = name;
    }
}

public class Main {
    public static void main(String[] args) {
        ReadWriteProperty<Person, String> nameProperty = new ReadWriteProperty<Person, String>() {
            @Override
            public String getValue(Person obj) {
                return obj.getName();
            }
            
            @Override
            public void setValue(Person obj, String value) {
                obj.setName(value);
            }
        };
        
        Person person = new Person();
        nameProperty.setValue(person, "John");
        System.out.println(nameProperty.getValue(person));  // Output: John
    }
}
