여기에서 실행 결과가 ImmutableAddress로 나오는데 왜 그런건가요??

선생님것을 보면 Address 클래스로 나오는데...

다시 삭제했다가 다시 만들어도 실행 결과에서 ImmutableAddress클래스로 나오는 이유를 모르겠습니다.

package lang.immutable.address;

public class MemberMainV1 {

    public static void main(String[] args) {
        Address address = new Address("서울"); // x005

        MemberV1 memberA = new MemberV1("회원A", address); // x002
        MemberV1 memberB = new MemberV1("회원B", address); // x003

        // 회원A, 회원B의 처음 주소는 모두 서울
        System.out.println("memberA = " + memberA);
        System.out.println("memberB = " + memberB);

        memberB.getAddress().setValue("부산");
        System.out.println("부산 -> memberB.address");
        System.out.println("memberA = " + memberA);
        System.out.println("memberB = " + memberB);

        -실행결과

        memberA = MemberV1{name='회원A', address=ImmutableAddress{value='서울'}}
        memberB = MemberV1{name='회원B', address=ImmutableAddress{value='서울'}}
        부산 -> memberB.address
        memberA = MemberV1{name='회원A', address=ImmutableAddress{value='부산'}}
        memberB = MemberV1{name='회원B', address=ImmutableAddress{value='부산'}}

    }
}
