题目
设计一个配备类 Equipment，该类有两个属性，一个是名字 name，类型为字符串类型，另一个是价格 price，类型为 int。而后实例化 3 件具体配备并打印其名字和价格。
剖析
次要考查类的创立以及如何实例化一个对象，并且随同有重写 toString() 办法。
实现

题目
当初王者光荣很火，置信大部分人也玩过，那咱们就来定义一个英雄类，用来作为王者光荣里的各英雄的父类。一般来讲，一个英雄有名字、血量、蓝量、初始挪动速度、攻打值……，咱们须要做的，就是将这些作为类的属性尽可能地增加到类中。
剖析
次要考查如何定义类，以及如何增加类中的属性，而且如何抉择属性的数据类型。

题目
既然王者光荣中的英雄有很多属性，而且也有很多配备，咱们买了配备之后就会给咱们的英雄加血量、加攻打值或则加挪动速度之类。咱们就来定义几个办法，用于购买配备后给咱们的英雄减少属性值。
剖析
次要考查如何给咱们的类定义方法。

题目
设计一个办法，用于计算你的 BMI 值是多少，其中 BMI = 体重（kg）/ 身高（m） * 身高（m）
剖析
输出体重和身高，而后调用办法计算 BMI 即可。
实现

题目
通过输出的月份，判断该月处于哪一个节令。
剖析
次要考查 switch 多分支的判断，而且要留神，要完结一个分支的判断时，须要有 break。要留神 switch 自从 JDK 1.7 及之后是反对 String 类型的。当然也能够应用 if 进行判断。
实现
