大家好，我是Ziph！
游戏角色题目：
在之前的游戏角色Role程序上进行修改
游戏角色（封装、继承、多态版）
-
创建Role接口，包含两个方法：
1）int attack(); 表示攻击，返回值表示对敌人的伤害
2）void practise(); 表示练习。练习之后对敌人的伤害会增加 -
创建NamedRole类，该类为一个抽象类，实现了Role 接口，并有两个属性：
1）name：角色的名字
2）age：角色的年龄 -
增加MagicStick接口。该接口表示法师使用的法杖。接口中包含一个方法：
1）int fire() -
为MagicStick类增加两个实现类，分别为GreenStick和BlackStick。其中，对于这两个类的fire方法：
1）GreenStick 平时返回1，夏天（6~8月）使用时返回2
2）BlackStic奇数月返回1，偶数月返回2 -
修改Magicer类
1）为法师类增加MagicStick类的属性stick，表示法师使用的法杖
2）让其继承自NamedRole类，并实现attack和practise 功能
3）int attack()返回值为法师的魔法等级(level)*每一级的固定伤害(5)
4）void practise()方法：- 当法师的stick属性为null时，调用 practise则level++
- 当法师的stick不为null时，调用practise 方法时，法师的等级level满足：level = level + 1 + stick.fire()；即：法师的等级增加为1+stick 属性的fire方法的返回值
-
增加Weapon接口，表示战士使用的武器。Weapon接口中定义了两个方法：
1）void setSoldier(Soldier s); 该方法表示设置武器的使用者
2）int fire(); 该方法的返回值表示战士使用该武器时，对敌人的伤害值 -
为 Weapon 增加两个实现了，Bolo，表示大刀，Pike，表示长矛
1）当 soldier 的年龄大于等于 18 岁时，fire 方法返回 100
2）当 soldier 年龄小于 18 岁时，fire 方法返回 50 -
Pike：Pike 类有一个属性：name，表示长矛的名字
1）当长矛的名字和战士的名字一致时，fire 方法返回 1000
2）当长矛的名字和战士的名字不一致时，fire 方法返回 25 -
修改 Soldier 类
1）为 Soldier 类增加一个 Weapon 属性，表示战士的武器
2）让其继承自 NamedRole 类，并实现 attack 和 practise 功能。其中- Soldier 的 attack() 返回值为战士的 hurt 值与武器的 fire()返回值的 和，即：总攻击输出 = 战士的徒手伤害值 + 武器的伤害值
- practise()方法：每调用一次则战士的 hurt 值+10
-
编写相应的测试代码
这次我是分包写的，如图：（而且途中还偶遇一个空指针，卡了我一会。。。）
