创建一个类，提供与java .lang.Math同名的所有方法，但每个方法均按度数而非弧度进行运算。具体要求是:在自己编写的类中，对Math类中的每一个方法加一层包装。(Create a class that provides all methods with the same name as java. lang. Math, but each method operates in degrees rather than radians. Specific requirements are: in their own class, each method in the Math class with a layer of packaging.)

泛型是Java SE 1.5的新特性，泛型的本质是参数化类型，也就是说所操作的数据类型被指定为一个参数。这种参数类型可以用在类、接口和方法的创建中，分别称为泛型类、泛型接口、泛型方法。Java语言引入泛型的好处是安全简单。 (Generic is the Java SE 1.5 new features, the nature of generic type parameters, that is operated by the data type is designated as a parameter. This parameter type can be used in class, the creation of interfaces and methods of the respective category as generic, generic interfaces, generic approach. Java language advantages of the introduction of generic security simple.)

XML转换开源包，就是让你配置一个 XML 转到 Java Object 对应的程序, 当一些 XML 中特定的属性将会触发一些被称为 rules 的动作, 有一些属性是已经被定义好了, 当然你也可以建立自己所需要的. 而 Digester 也包含了以下高级的特性 : *能够嵌入你原本的对应方式, 而不会影响你的需求. *自定义(Customized)的 namespace-aware 的执行, 以至于你可以定义 rules 恰当独特的 XML 命名空间. *将所有的 Rules 放入 RuleSets 可以简单方便地重复使用在其它需要相同类型的项目之中(XML conversion open-source package, is to allow you to configure an XML to Java Object corresponding to the procedure, when a number of XML specific attributes will trigger a number of actions called rules, some properties are already defined well, of course, you can also create their own needs. and Digester also includes the following advanced features:* can be embedded in your original correspondence, rather not affect your needs.* Custom (Customized) the implementation of the namespace-aware, so that You can define rules appropriate to the unique XML namespace.* all the Rules into RuleSets can simply and easily re-use in other types of projects require the same among the)
