If a property has no annotation, but only a getter, it should be read-only.

[beyond-seunghyun]

If a property has no annotation, but only a getter, it should be read-only.

For example.

public class Cap {

    public String getBrand() {
        return "no brand";
    }
}

A Cap's property "brand" should be read-only. Because there's no way to write "brand".
