ImmutableAddress에서 value를 final로 설정했는데

MemberV2에서 setAddress를 쓸 수 있는 건가요?

final로 선언하면 setter를 못 쓴다고 알고 있어서 질문합니다.

(불변 객체 - 값 변경 강의입니다.)

package immutable.address;

public class ImmutableAddress {

    private final String value;

    public ImmutableAddress(String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }

    @Override
    public String toString() {
        return "Address{" +
                "value='" + value + '\'' +
                '}';
    }
}

package immutable.address;

public class MemberV2 {

    private String name;
    private ImmutableAddress address;

    public MemberV2(String name, ImmutableAddress address) {
        this.name = name;
        this.address = address;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public ImmutableAddress getAddress() {
        return address;
    }

    public void setAddress(ImmutableAddress address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "MemberV1{" +
                "name='" + name + '\'' +
                ", address=" + address +
                '}';
    }
}
