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.)

说明：  编写一个复数类，可以进行复数加法和减法运算。编写一个包含main方法的类（应用程序）测试该复数类。要求该复数类至少包含一个无参的构造方法和一个带参的构造方法；数据成员包括复数的实部和虚部，为double类型；包括两个方法，分别实现复数的加法和减法运算。(Write a complex class, which can add and subtract complex numbers. Write a class (application) containing the main method to test the complex class. The complex class is required to include at least one parametric construction method and one parametric construction method; the data members include the real and imaginary parts of the complex, which are of double type; and two methods are included to realize the addition and subtraction operations of the complex respectively.)
