用个骰子

课程理解

  再次翻阅

  1. 深入理解Java面向对象三大特性 封装 继承 多态
  2. UML类图(上):类、继承和实现
  3. UML类图几种关系的总结

    大致理解:泛化,实现,依赖,关联,聚合,组合,之间的关系。以及类图的画法。理清关系,画好类图,这样会起到事半功倍的效果,对写程序的效率也有提高。

设计实现

如图所示的各类间关系,当Test1(图形化)直接使用两个Dice类的方法;当Test2(控制台)通过使用骰盅Cup类调用Dice类的方法来随机选择学生,直接用Dice类随机选择奖品。

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.Cup.java

//骰盅类的实现:可以放入多个骰子。
public class Cup {
	private int num=1;// num记录骰子的个数,默认为一个
	private Dice dice[]; //声明骰子数组

	public Cup(){ //往骰盅放入一个骰子
		dice = new Dice[num]; 
	}
	public Cup(int num){ //往骰盅放入多个骰子
		this.num = num;
		dice = new Dice[num];
	}
	public void roll(){ //摇动骰盅
		int i;
		for(i=0;i<num;i++){
			dice[i] = new Dice();	
		}
	}

	public int getValue(){  //一个骰子开盅看大小,并返回该数值
		return (dice[0].getValue());
	}
	
	public void getValues(int a[]){  //多个骰子开盅看大小。并将每个骰子的数值通过整型数组传出
			int i;
			for(i = 0;i < num;i++)
				a[i]=dice[i].getValue();
		}		
		public int getTotal(){ //返回多个骰子的总数值
			int sum=0,i;
			for(i=0;i<num;i++){
				sum += dice[i].getValue();
			}
			return sum;				
		}
	}

3.Reward.java


public class Reward {
	private int r =0;
	private int max = 6;
	String[] rewards ={"橡皮檫","作业本","钢笔","尺子","计算器","订书机"};
	
	public Reward(){
        r = (int)(Math.random() * (max-1) ) ;  //获得一个0-(max-1)的随机数
    }
	
	public void change(){
		r = (int)(Math.random() * (max-1) ) ;
	}
	
	public String getReward(){
		return rewards[r];
	}
	
	public int getr(){
		return r;
	}
	
	public String getReward(int num) {  
		return rewards[num];
	}
}

测试运行

1.图形化界面




2.控制界面

总结

  对于的图形化的界面接触较少,预估完成控制台界面30分,而图形化界面只能一脸懵懂的状态,最后参照@稽美大学小学生 大佬的程序,模仿着弄出一个小成品。总的来说,大致一个下午的时间,在模仿着弄出的时间比较多。
