作业 1. 抽象类Expression（表达式）既可以表达算术运算，⼜又可以表达逻辑运算，但两种运算不不能 混合。Expression还有两个抽象⼦子类BinOp（⼆二元运算）和UnOp（⼀一元运算）。还有另⼀一 个⾮非抽象⼦子类Const（常量量）可以表达Integer和Boolean。Expression要有两个抽象⽅方法 evaluate（）和toString（）。 算术运算处理理的都是Integer，⽽而逻辑运算处理理的都是Boolean。因为Expression这两类都可 以处理理，所以请声明类型参数。然后给这四个类都添⼊入构造函数。 为BinOp（⼆二元运算）加上6个⼦子类，四个算术运算：+，-，*，/，和两个逻辑运算：∧ 与， ∨ 或。 为UnOp（⼀一元运算）加上两个⼦子类，⼀一个算术运算：-(既是⼆二元运算⼜又是⼀一元运算)，和⼀一 个逻辑运算：¬ 否。尽可能让这8个⼦子类的构造函数简单。 evaluate（）的⼯工作就是运算输⼊入的表达式然后输出结果。 如：(new MulOp(new Const(3), new AddOp(new Const(1), new Const(2)))).evaluate() 输出的结果应该是9 (new AndOp(new Const(true),new OrOp(new Const(false), new Const(true)))).evaluate() 输出的结果则是true toString（）的⼯工作是将算术表达式都正确地print出来 如：(new MulOp(new Const(3), new AddOp(new Const(1), new Const(2)))).toString（） 结果是3*（1+2） 在⼀一个新的ATest类中的main中⽤用三个包含⾄至少5个Expression的object的表达式测试 evaluate和toString 结束时应有的⽂文件：Expression.java, Const.java, BinOp.java, UnOp.java, AddOp.java, MulOp.java, DivOp.java, SubOp.java,

### function.arity > Functions which manipulate the way functions work with their arguments. ——————————————————————————– #### arity **Signature:** `_.arity(numberOfArgs:Number, fun:Function)` Returns a new function which is equivalent to `fun`, except that the new function’s `length` property is equal to `numberOfArgs`. This does **not** limit the function to using that number of arguments. It’s only effect is
