前言
学习了关于集合类的知识，我们可以做一个小项目来加深对集合类知识的学习！
一、项目要求
代码实现，一副扑克牌(不包括大小王)的购买、打乱、发牌。
二、具体实现
2.1 Card类
class Card {
private int rank;//数字
private String suit;//花色
public Card(int rank, String suit) {
this.rank = rank;
this.suit = suit;
}
@Override
public String toString() {
return "[ " + this.suit + ":"+this.rank+" ]";
}
}
2.2 生成扑克牌
private static final String[] suits = {"♥", "♠", "♣", "♦"};
//假设没有大小王：1 2 3............. 11 12 13
public static List<Card> buyCard() {
ArrayList<Card> cards = new ArrayList<>();
for (int i = 0; i < 4; i++) {
for (int j = 1; j <= 13; j++) {
// String suit = suits[i];
// int rank = j;
// Card card = new Card(rank, suit);
// cards.add(card);
cards.add(new Card(j,suits[i]));
}
}
return cards;
}
2.3 打乱顺序
private static void swap(List<Card> cards, int i, int j) {
Card tmp = cards.get(i);
cards.set(i,cards.get(j));
cards.set(j,tmp);
}
//洗牌
public static void shuffle(List<Card> cards) {
int size = cards.size();
for (int i = size-1; i > 0 ; i--) {
Random random = new Random();
int rand = random.nextInt(i);
swap(cards, i, rand);
}
}
2.4 发牌
System.out.println("揭牌：3个人每个人轮流揭牌5张牌");
ArrayList<List<Card>> hand = new ArrayList<>();
List<Card> hand1 = new ArrayList<>();
List<Card> hand2 = new ArrayList<>();
List<Card> hand3 = new ArrayList<>();
hand.add(hand1);
hand.add(hand2);
hand.add(hand3);
//每个人，轮流揭牌
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
Card card = cards.remove(0);
hand.get(j).add(card);
}
}
三、Test.java
import java.util.ArrayList;
import java.util.List;
import java.util.Random;
class Card {
private int rank;//数字
private String suit;//花色
public Card(int rank, String suit) {
this.rank = rank;
this.suit = suit;
}
@Override
public String toString() {
return "[ " + this.suit + ":"+this.rank+" ]";
}
}
public class Test1 {
private static final String[] suits = {"♥", "♠", "♣", "♦"};
//假设没有大小王：1 2 3............. 11 12 13
public static List<Card> buyCard() {
ArrayList<Card> cards = new ArrayList<>();
for (int i = 0; i < 4; i++) {
for (int j = 1; j <= 13; j++) {
// String suit = suits[i];
// int rank = j;
// Card card = new Card(rank, suit);
// cards.add(card);
cards.add(new Card(j,suits[i]));
}
}
return cards;
}
private static void swap(List<Card> cards, int i, int j) {
Card tmp = cards.get(i);
cards.set(i,cards.get(j));
cards.set(j,tmp);
}
//洗牌
public static void shuffle(List<Card> cards) {
int size = cards.size();
for (int i = size-1; i > 0 ; i--) {
Random random = new Random();
int rand = random.nextInt(i);
swap(cards, i, rand);
}
}
public static void main(String[] args) {
List<Card> cards = buyCard();
System.out.println("买牌：" + cards);
shuffle(cards);
System.out.println("洗牌：" + cards);
System.out.println("揭牌：3个人每个人轮流揭牌5张牌");
ArrayList<List<Card>> hand = new ArrayList<>();
List<Card> hand1 = new ArrayList<>();
List<Card> hand2 = new ArrayList<>();
List<Card> hand3 = new ArrayList<>();
hand.add(hand1);
hand.add(hand2);
hand.add(hand3);
//每个人，轮流揭牌
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
Card card = cards.remove(0);
hand.get(j).add(card);
}
}
System.out.println("第一个人的牌："+ hand1);
System.out.println("第二个人的牌："+ hand2);
System.out.println("第三个人的牌："+ hand3);
System.out.println("剩下的牌："+cards);
}
public static void main1(String[] args) {
// 1. 构造一副扑克牌
// 2. 揭牌
Card card = new Card(3,"♥");
System.out.println(card);
}
