英雄类

package LOLDemo;/*** @ClassName: Hero* @Description: *     自定义一个英雄类*    0.英雄类中加入“经验值”，“等级”，“攻击力”等属性变量,加入“击打”方法，击打的目标是怪物，击打的结果是怪物的生命值-英雄攻击力*	  1.英雄的级别最低为0，最高为30级，*	  2.经验值最低为0，最高为30级时的经验值，*	  3.该类中要求有一个含有 参数的构造函数，参数为英雄的经验值,初始化时要保证经验值在要求范围之内，*	  4.通过经验值计算英雄的级别，英雄的级别计算公式如下: N=当前级别，EXP (经验值) =30 (N^3+5N) -80*    5.构建一个无参的构造方法，将经验值设置为0*    6.利用英雄类无参和带有参数的构造函数分别构建英雄对象,并输出英雄的等级和经验值。*            自加：攻击力：0级100，每升一级攻击力加20* @Author: Wanglt   * @CreateDate: 2020年2月27日   **/
