骰子修改

 

经过对Java中面向对象的理解，重新对骰子进行修改，仅保留了一般功能！

 

Test类：

import java.util.Scanner;

public class Test 
{
    public static void main(String[] args) 
    {
        int num;
        System.out.println("请输入骰子的个数:");
        @SuppressWarnings("resource")
        Scanner sc = new Scanner(System.in);
        num = sc.nextInt();
        
        Cup cup = new Cup(num);
        cup.rollPrint();
    }

}

Cup类：

public class Cup 
{
    private int num;
    @SuppressWarnings("unused")
    private Dice[] dice;
    
    public Cup(int num)
    {
        this.num = num; 
        dice = new Dice [num];
        for(int i = 0; i < num; i++)
        {
            dice[i] = new Dice();
            
        }
    }
    
    public void setNum(int num)
    {
        this.num = num;
    }
    
    public int getNum()
    {
        return num;
    }
    
    public void rollPrint()
    {
        
        for(int i = 0; i < num; i++)
        {
            System.out.print("第" + (i+1) + "个骰子的面值:" + dice[i].getFaceValue());
            System.out.println();
        }
    }
}

Dice类：

public class Dice 
{
    private int faceValue;
    
    public Dice()
    {
        faceValue = (int)(Math.random() * 6) + 1;
    }
    
    public int getFaceValue() 
    {
         return faceValue;
    }
}

运行结果：
