Case development of landlord fighting game

Landlords game case development

---

Business needs analysis :

Playing cards against landlords , Shuffle , Licensing , Sort （ Expand knowledge ）, Look at cards .
Business : All in all 54 card .
points : "3","4","5","6","7","8","9","10","J","Q","K","A","2"
Design and color : "", "", "", ""
Big and small king : "" , ""
The points should be combined separately 4 Plant designs , One for each king .
fight against landlords ： issue 51 card , be left over 3 As a card .

Function realization ：

1. Make cards .
2. Shuffle .
3. Definition 3 Players
4. Licensing .
5. Sort （ expand ）
6. Look at cards

Code section ：

Card class and its attribute method ：

public class Card {
    private String size;
    private String color;
    private int index; //  The real size of the card 

    public Card(){
    }

    public Card(String size, String color, int index) {
        this.size = size;
        this.color = color;
        this.index = index;
    }

    public String getSize() {
        return size;
    }

    public void setSize(String size) {
        this.size = size;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public int getIndex() {
        return index;
    }

    public void setIndex(int index) {
        this.index = index;
    }

    @Override
    public String toString() {
        return size + color;
    }
}

game Implementation class :

public class GameDemo {
    /**
      1、 Define a static collection storage 54 Card object 
     */
     public static List<Card> allCards = new ArrayList<>();

    /**

     */

        String[] sizes = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
        // 4、 Define decor ： The number is determined , Type determination , Using arrays 
        String[] colors = {"", "", "", ""};
        // 5、 Combine points and decors 
        int index = 0; //  The size of the record board 
        for (String size : sizes) {
            index++;
            for (String color : colors) {
                // 6、 Encapsulated into a card object .

    public static void main(String[] args) {

        // 9. Shuffle 
        Collections.shuffle(allCards);
        System.out.println(" After the shuffle " + allCards);

        // 10. Licensing  （ Define three players , Each player's card is also a collection container ）

        for (int i = 0; i < allCards.size() - 3; i++) {
            // Get the current card object first

}

summary ：

First, define a static collection storage 54 Card object , Then initialize the card with a static code block , Combine the decor size of the card and package it into an object , Stored in a static collection container , Use Collections Tools to shuffle , And define three player objects , Send the disordered cards to three objects in order , Rewrite the comparison rules , According to the rules , Press the cards of three objects Descending Sort and output .
