  • 第四次作業(yè) 1、 創(chuàng)建一個Animal(動物)類

    第四次作業(yè) 1、 創(chuàng)建一個Animal(動物)類,讓Horse(馬),Dog(狗),Cat(貓)等動物繼承Animal類。在Animal類中定義一些方法,讓其子類重寫這些方法,編寫一個運(yùn)行時多態(tài)的程序。 創(chuàng)建一個Animal類型的數(shù)組,在其中填充不同子類,然后調(diào)用自己的父類中的方法,看看會有什么情況發(fā)生。 2、 修改練習(xí)3.3,使Animal成為一個接口。 3、 在面向?qū)ο蟮睦L圖應(yīng)用應(yīng)用程序中,可以繪制圓形、矩形、直線等很多其他的圖形對象。這些對象都具有相同的特定狀態(tài)(例如位置、方向、線條顏色和填充顏色)和行為(例如移動、旋轉(zhuǎn)、改變大小和繪制)。一些狀態(tài)和行為對所有圖形是相同的,例如位置、填充顏色和移動。另一些狀態(tài)和行為需要不同的實現(xiàn),例如改變大小和繪制。所有GraphicObject都知道如何繪制自己和如何改變自己的大?。恢徊贿^完成的操作不同。 請設(shè)計GraphicObject類和所有子類的方法,其中用到抽象類和抽象方法、抽象方法、方法的重寫和多態(tài)、super關(guān)鍵字等概念。并測試其正確性。他們之間的關(guān)系用類圖表示。 4 用策略模式實現(xiàn)網(wǎng)上書城不同類型的圖書折扣策略,計算出每種類型的圖書的價格。并編程測試之。

  • SDN Software Defined Networks

    The first question most readers of an O’Reilly book might ask is about the choice of the cover Animal. In this case, “why a duck?” Well, for the record, our first choice was a unicorn decked out in glitter and a rainbow sash. That response always gets a laugh (we are sure you just giggled a little), but it also brings to the surface a common perception of software-defined networks among many expe‐ rienced network professionals. Although we think there is some truth to this perception, there is certainly more meat than myth to this unicorn.

  • RFID AND SENSOR NETWORKS Architectures

    Radio frequency identification (RFID) technology is witnessing a recent explosion of development in both industry and academia. A number of applications include supply chain management, electronic payments, RFID passports, environmental monitoring and control, office access control, intelligent labels, target detection and tracking, port management, food production control, Animal identification, and so on. RFID is also an indispensable foundation to realize the pervasive computing paradigm—“Internet of things.” It is strongly believed that many more scenarios will be identified when the principles of RFID are thoroughly understood, cheap components available, and when RFID security is guaranteed.

  • Wireless Identification

    We are in the era of ubiquitous computing in which the use and development of Radio Frequency Iden- tification (RFID) is becoming more widespread. RFID systems have three main components: readers, tags, and database. An RFID tag is composed of a small microchip, limited logical functionality, and an antenna. Most common tags are passive and harvest energy from a nearby RFID reader. This energy is used both to energize the chip and send the answer back to the reader request. The tag provides a unique identifier (or an anonymized version of that), which allows the unequivocal identification of the tag holder (i.e. person, Animal, or items).
