Javaは集合で簡単な闘地主発札を実現

配列、コレクションの作成、データの保存

public class FightAgainstLandlords {
    /**
     * poker  ，  54  
     */
    private ArrayList poker;

    /**
     * colors        
     */
    private String[] colors;

    /**
     * numbers       
     */
    private String[] numbers;
}

構造方法

public class FightAgainstLandlords {
    public FightAgainstLandlords(ArrayList poker, String[] colors, String[] numbers) {
        this.poker = poker;
        this.colors = colors;
        this.numbers = numbers;
    }
}

トランプの順序を乱す方法の定義

public class FightAgainstLandlords {
    /**
     *   54  
     */
    public ArrayList fiftyFive() {
        for (String color: colors) {
            for (String number: numbers) {
                poker.add(color + number);
            }
        }
        poker.add("  ");
        poker.add("  ");
        //   ，  Collections      shuffle()，               
        Collections.shuffle(poker);
        return poker;
    }
}
