e5_2:关于继承和重载：

编写一个Java应用程序，设计一个运输工具类Transport，包含的成员属性有：速度(pace)、载重量(load)；汽车类Vehicle是Transport的子类，其中包含的属性有：车轮的个数(wheels)和车重(weight)；飞机Airplane类是Transport类的子类，其中包含的属性有：机型(enginetype)和发动机的数量(engines)，每个类都有相关数据的输出方法。如对Transport类，就有getload()和getpace()方法获得对象的速度和载重量，有show()方法可以在屏幕上输出对象的速度和载重量，有构造方法（带参数）可以初始化某运输工具对象的速度和载重量。请定义汽车类和飞机类的构造方法和get方法，再用一个主类的main()分别定义这三个类的对象，设置其属性，并输出相应的属性值。 -e5_2: About inheritance and overloading:

Write a Java application, to design a vehicle class Transport, including members of the attributes are: speed (pace), load (load)　Automotive Transport Vehicle is a subclass, which contains the attributes: the number of wheels (wheels) and weight (weight)　Aircraft Transport Airplane class is a subclass, which contains attributes: type (enginetype) and the number of engine (engines), each class has a data output method. Such as the Transport category, there getload () and getpace () method to obtain the object s speed and load, a show () method of the object on the screen output speed and load, a constructor (with parameters) to the initial The object of a vehicle speed and load. Define auto and aircraft constructor classes and get methods, then a main class main () are defined three classes of objects, setting its properties, and output the corresponding property value.
