승연님 안녕하세요!
블랙잭 미션 잘 구현해주셨네요 :)

몇가지 코멘트를 남겼으니 확인부탁드리겠습니다!

vsh123 · 2022-02-18T08:41:48Z

README.md

-# java-blackjack
+# java-blackjack
+
+# 연료주입


기능 구현 목록 작성 👍

vsh123 · 2022-02-18T08:42:08Z

src/main/java/fuel/domain/Sonata.java

+    private static final int FUEL_EFFICIENCY = 10;
+
+    public Sonata(final double distance) {
+       super(distance, "Sonata");


매직넘버를 상수화 해주면 어떨까요?! 다른 객체들도 한번씩 살펴봐주시면 좋을 것 같아요 :)

vsh123 · 2022-02-18T08:43:45Z

src/main/java/fuel/domain/RentCompany.java

+public class RentCompany {
+    private static final String NEWLINE = System.getProperty("line.separator");
+
+    private final List<Car> carLists = new ArrayList<>();


List라는 특정 Collection명은 제거해주는게 어떨까요? cars로도 의미가 충분해보여요!

Suggested change

private final List<Car> carLists = new ArrayList<>();

private final List<Car> cars = new ArrayList<>();

vsh123 · 2022-02-18T08:44:34Z

src/main/java/fuel/domain/RentCompany.java

+    private final List<Car> carLists = new ArrayList<>();
+
+    public static RentCompany create() {
+        return new RentCompany();


create()를 통해서만 생성이 가능하게하려면, 기본 생성자의 접근제한자를 private으로 선언해보면 어떨까요?

vsh123 · 2022-02-18T08:45:50Z

src/main/java/fuel/domain/Car.java

+    }
+
+    protected double getChargeQuantity() {
+        return getTripDistance() / getDistancePerLiter();


getTripDistance()메서드를 호춣하는 것보다 distance를 바로 호출해보면 어떨까요?

vsh123 · 2022-02-18T08:53:01Z

src/main/java/blackjack/controller/GameLauncher.java

+
+    private static final int BLACK_JACK_SUM_LIMIT = 21;
+
+    public void start() {


메서드가 10 line을 넘어가는 것 같아요!!
아래의 요구사항을 지켜보면 어떨까요?

함수(또는 메서드)의 길이가 10라인을 넘어가지 않도록 구현한다.
함수(또는 메소드)가 한 가지 일만 하도록 최대한 작게 만들어라.

vsh123 · 2022-02-18T08:53:48Z

src/main/java/blackjack/controller/GameLauncher.java

+        OutputView.printDealerCardSum(dealer);
+        OutputView.printPlayerCardSum(players);


두번의 View호출을 한번으로 줄일 수 없을까요?

View호출이 Console이아닌 Network기반이라면 Network비용이 더 소모될 것 같아요!

vsh123 · 2022-02-18T08:55:47Z

src/main/java/blackjack/domain/gamer/Players.java

+public class Players {
+
+    private final List<Player> players = new ArrayList<>();
+    private final String[] playerNames;


해당 필드는 생성 이후 쓰이지 않는데요! 들고있을 필요가 있을까요?

vsh123 · 2022-02-18T08:57:43Z

src/main/java/blackjack/domain/gamer/Players.java

+                Collectors.toMap(player -> player, player -> player.getMatchResult(player, dealer),
+                    (player1, player2) -> player1, LinkedHashMap::new)));


이 경우에는 동일한 Player가 있을 경우 mergeFunction을 수행하는 것이 아닌, 에러를 발생시켜야할 것 같은데요! 어떻게 생각하시나요?(동일한 Player가 존재할 수 있나요?)

아래와 같이 작성이 가능합니다!

Suggested change

Collectors.toMap(player -> player, player -> player.getMatchResult(player, dealer),

(player1, player2) -> player1, LinkedHashMap::new)));

Collectors.toMap(Function.identity(), player -> player.getMatchResult(player, dealer),

(player1, player2) -> player1, LinkedHashMap::new)));

vsh123 · 2022-02-18T08:59:03Z

+        for(Card card : cards) {
+            this.cards.add(card);
+        }


addAll을 이용해보면 어떨까요?

Suggested change

for(Card card : cards) {

this.cards.add(card);

}

this.cards.addAll(cards);
