简单的棋盘

课程的理解

在这几次的使用类，构建类间的关系实践中，已经懂得一部分类的概念，也能构建相对规范实用的类。类图的画法也基本上可以分辨得出来，但是有几种自己实践中没用到的，印象不深，还得翻一翻书才能分辨。使用类可以使得整个代码的结构清晰，哪一部分的功能调用哪一个类，这样在出现问题的时候，能够精准快速地找到问题和改正问题。当然不仅如此，还有要添加新功能，还是修改一些方法，直接在类中修改，而不需要每个传递到的地方都要修改，很大地提高了效率。在开始作业前，我考虑了Map类需要有哪些方法什么变量，进而将Map类分割成由Zone类组成，再将两者关系结构考虑清楚，还有游戏者Role的实现。

设计实现

如图所示的各类间关系，MapGui调用了Dice类，Role类，Map类，Map类调用Zone类。各类间所带方法和参数如图所示。

代码说明

1.Dice.java

//骰子类的实现
public class Dice {
    private  int faceValue;  //定义骰子面值
    
    public Dice(){
        faceValue = (int)(Math.random() * 6) + 1;  //获得一    个1-6的随机数
    }
    public void roll(){  //摇骰子
        faceValue = (int)(Math.random() * 6) + 1;
    }

    public  void unnormalroll(){  //摇不出4的骰子
        while(faceValue==4){
            faceValue = (int)(Math.random() * 6) + 1;
        }
    }

    public int getValue(){  //获得骰子数值
        return faceValue;
    }
}

2.Role.java

public class Role {
    private String name;
    private int money = 0;
    private int location = 0;
    
    public Role(String name,int money) {
        this.name = name;
        this.money = money;
    }
    
    public String getName() {
        return this.name;
    }
    public void changMoney(int money) {
        this.money += money;
    }
    
    public int getMoney() {
        return this.money;
    }
    
    public void move(int i,int limit) {
        this.location = this.location +i;
        if(this.location > limit-1 ) {
            this.location = this.location-limit+1;
        }
    }
    
    public int getlocation() {
        return this.location;
    }
}

3.Zone.java

public class Zone {
    private int price = 0;
    private int fee = 0;
    private String owner = null;
    
    public Zone(int price) {
        this.price = price;
        this.fee = (int)(price * 0.1);
    }
    
    public String showOwner() {
        return this.owner;
    }
    
    public int showPrice() {
        return this.price;
    }
    
    public int showFee() {
        return this.fee;
    }
    
    public void changOwner(String owner) {
        this.owner = owner;
    }
}

4.Map.java

public class Map {
    private int num;
    private Zone zone[]; 
    
    public Map(int num){ 
        this.num = num;
        zone = new Zone[num];
    }
    
    public void modul1() {
        int i;
        zone[0] = new Zone(0);
        for(i=1;i<num;i++) {
            switch(i%5) {
                case 0: zone[i] = new Zone(1000);break;
                case 1: zone[i] = new Zone(2000);break;
                case 2: zone[i] = new Zone(3000);break;
                case 3: zone[i] = new Zone(4000);break;
                case 4: zone[i] = new Zone(5000);break;
            }
        }
    }
    
    public int zoneValue(int i) {
        return zone[i].showPrice();
    }
    
    public int zoneFee(int i) {
        return zone[i].showFee();
    }
    
    public String zoneOwner(int i) {
        return zone[i].showOwner();
    }
    
    public void zoneOwe(int i,String owner) {
        zone[i].changOwner(owner);
    }
}

测试运行

由MapGui设置setting数组来决定游戏的初始参数（在这里，游戏人数4，名称分别为丁丁，迪西，拉拉，小波，初始金币为50000，回合数为20）

小结

个人在GUI界面方面有所缺漏，难以独立完成，通过参照子琦大佬的模式，模仿其中运行的方式，从而适配自己的结构，也改进了其中一些方式，缩减一半代码量。基本上还是在图形界面消耗的时间最多。
