一共使用了建造者模式、状态模式、命令模式、策略模式、单件模式这5个设计模式。 本次课程设计是开发一款有多个面板的计算器。不仅有针对日常生活“标准型”面板、针对理工科计算的“科学型”面板、针对于编程人员计算“程序员”面板，还别出心裁地开发了针对中学生的数学学习“特色型”面板，有利于他们检查自己数学作业答案和试卷答案。 本计算器实现了当点下拉菜单中标准型、科学型、程序员和特色型等选项可以切面不同的计算器面板。 本计算器实现了当选中按钮时，按钮呈现如黄水晶般色调渐变的颜色。 本计算器实现了自定义左上角图标的功能。 关键词: 建造者模式 状态模式 命令模式 策略模式 单件模式 计算器 多面板 标准型 科学型 程序员 特色型 初等函数 二进制 八进制 十六进制 分解质因数 最简二次根式 一元二次方程 保留根号 小数转分数 循环小数(We used a total of builder mode, the state mode, command mode, the policy mode, single mode these five design patterns. This course is designed to develop a plurality of panels of a calculator. Not only for everyday life, " standard" panel for science and engineering computing " science-based" panel, for the calculation of " programmer" panel to programmers, even inspired to develop the learning of mathematics for high school students " special type" panel, there are benefit them check their math homework answers and answers to tests. The calculator achieved her point standard drop-down menu, science-based, programmers and characteristics of different type and other options section of the calculator panel. This calculator implements the election of the button, the button showing topaz hue gradient colors. The calculator icon in the top left corner to achieve a custom function. Keywords: Builder mode status Mode Command Mode Strategy Mode single mode )

说明：  利用前面提到的SupplyDepot、Transport和CapableOfBeingRefefuelled类/接口，为Air-plane增加一个main()方法，然后为supplyDepot等增加必要的字段、参数和代码，以便CapableOfBeingRefefuelled能够告诉service（）方法需要加多少油。同时要确保Depot中的油应相应地减少，而实现CapableOfBeingRefefuelledi的类对象应相应地增加。(Using the upplyDepot, Transport and ApableOfBeingRefefuelled classes/interfaces mentioned above, add a main () method to Air-plane, and then add the necessary fields, parameters and codes to supplyDepot, so that CapableOfBeingRefefuelled can tell service () how much fuel the method needs. At the same time, we should ensure that the oil in Depot should be reduced accordingly, and the class objects that implement Capable OfBeingRefefuelledi should be increased accordingly.)
