java实验代码

实验任务任务1需求：具有照像功的设备：手机Phone，数码照像机Camera,平板电脑Tabletpc请遵循照像功能Photographable实现takePhoto的功能。实现效果图如下：代码如下：各种设备终端的抽象类packagetakePhoto;publicabstractclassEquipment{privateStringname;publicEquipment(Stringname){super();}publicStringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}}定义一个照相功能的接口packagetakePhoto;publicinterfaceTakePhoto{publicabstractvoidTakePhotos();}定义一个手机的类继承设备类并且实现照相接口packagetakePhoto;publicclassPhoneextendsEquipmentimplementsTakePhoto{publicPhone(Stringname){super(name);System.out.println("---有参---"name);}publicvoidTakePhotos(){System.out.println(getName()":像素低");System.out.println(getName()"有傻瓜照相功能，还能打电话");}}定义一个照相机的类继承设备类并且实现照相接口packagetakePhoto;publicclassCameraextendsEquipmentimplementsTakePhoto{publicCamera(Stringname){super(name);System.out.println("---有参---"name);}@OverridepublicvoidTakePhotos(){System.out.println(getName()":像素很高");System.out.println(getName()"有夜间模式、微距模式等");}}定义一个平板的类继承设备类并且实现照相接口packagetakePhoto;publicclassTabletPCextendsEquipmentimplementsTakePhoto{publicTabletPC(Stringname){super(name);System.out.println("---有参---"name);}@OverridepublicvoidTakePhotos(){System.out.println(getName()":像素还行");System.out.println(getName()"屏幕大，看得爽，还能玩高清游戏");}}测试代码并显示结果packagetakePhoto;publicclassTest{publicstaticvoidmain(String[]args){Phonep1=newPhone("诺基亚");p1.setName("诺基亚");p1.TakePhotos();Phonep2=newPhone("小米");p2.setName("小米");p2.TakePhotos();Camerac=newCamera("索尼数码");c.setName("索尼数码");c.TakePhotos();TabletPCt=newTabletPC("ipad");t.setName("ipad");t.TakePhotos();}}任务2在几何图形中，按图形的几何维数分为平面图和立体图，所有的平面图都能计算周长和面积，所有的立体图都能计算表面积和体积.定义Shape2D和Shape3D接口，分别描述平面图和立体图的特征和行为，在Shape2D中定义计算周长和面积的方法，Shape3D继承Shape2D接口，新增计算体积的方法，定义Circle圆类和Sphere球类，分别实现Shape2D和Shape3D接口。代码如下：定义一个2D图形的接口packageShape;publicinterfaceShape2D{abstractdoubleGrith(doubler);abstractdoubleArea(doubler);}定义一个3D图形的接口packageShape;publicinterfaceShape3DextendsShape2D{abstractdoubleVolume(doubler);}圆的类实现2D接口packageShape;publicclassCircleimplementsShape2D{privatedoubler;publicdoublegetR(){returnr;}publicdoubleGrith(doubler){return3.14*2*r;}publicdoubleArea(doubler){return3.14*r*r;}}圆的球实现3D接口packageShape;publicclassBallimplementsShape3D{doubler;publicdoublegetR(){returnr;}publicdoubleArea(doubler){return4*3.14*r*r;}publicdoubleVolume(doubler){return(4.0/3.0)*r*r*r;}@OverridepublicdoubleGrith(doubler){return2*3.14*r;}}测试类并且输出显示packageShape;importjava.util.Scanner;publicclassTest{publicstaticvoidmain(String[]args){System.out.println("求圆的

请输入1，求球的参数请输入2：");Scannera=newScanner(System.in);inta1=a.nextInt();if(a1==1){Circlec=newCircle();System.out.println("请输入圆的半径：");doubler=a.nextDouble();System.out.println("圆的周长为："c.Grith(r));System.out.println("圆的面积为："c.Area(r));}else{Ballb=newBall();System.out.println("请输入球的半径：");doubler=a.nextDouble();System.out.println("球的周长为："b.Grith(r));System.out.println("球的面积为："b.Area(r));System.out.println("球的体积为："b.Volume(r));}}}3.某公司的雇员分为以下若干类：Employee：这是所有员工总的父类，属性：员工的姓名,员工的生日月份。方法：getSalary(intmonth)根据参数月份来确定工资，如果该月员工过生日，则公司会额外奖励100元。SalariedEmployee：Employee的子类，拿固定工资的员工。属性：月薪HourlyEmployee：Employee的子类，按小时拿工资的员工，每月工作超出160小时的部分按照1.5倍工资发放。属性：每小时的工资、每月工作的小时数SalesEmployee：Employee的子类，销售人员，工资由月销售额和提成率决定。属性：月销售额、提成率BasePlusSalesEmployee：SalesEmployee的子类，有固定底薪的销售人员，工资由底薪加上销售提成部分。属性：底薪。写一个程序，把若干各种类型的员工放在一个Employee数组里，写一个函数，打印出某月每个员工的工资数额。注意：要求把每个类都做成完全封装，不允许非私有化属性。代码如下：员工的基本类packageCompany;publicclassEmployee{Stringname;intmonth;floatsalary;publicEmployee(Stringname,intmonth){this.name=name;this.month=month;}publicfloatgetSalary(intmonth){if(this.month==month){return100;}else{return0;}}}SalariedEmployee：Employee的子类，拿固定工资的员工。属性：月薪packageCompany;publicclassSalariedEmployeeextendsEmployee{floatsalary;publicSalariedEmployee(Stringname,intmonth,floatsalary){super(name,month);this.salary=salary;}publicfloatgetSalary(intmonth) { returnsalarysuper.getSalary(month);  }}HourlyEmployee：Employee的子类，按小时拿工资的员工，每月工作超出160小时的部分按照1.5倍工资发放。属性：每小时的工资、每月工作的小时数packageCompany;publicclassHourlyEmployeeextendsEmployee{inthour;floatsalary;publicHourlyEmployee(Stringname,intmonth,inthour,floatsalary){super(name,month);this.hour=hour;this.salary=salary;}publicfloatgetSalary(intmonth){if(hour>160){return(float)(salary*160(hour-160)*salary*1.5super.getSalary(month));}else{returnsalary*hoursuper.getSalary(month);}}}SalesEmployee：Employee的子类，销售人员，工资由月销售额和提成率决定。属性：月销售额、提成率packageCompany;publicclassSalesEmployeeextendsEmployee{floatsum;floatrate;publicSalesEmployee(Stringname,intmonth,floatsum,floatrate){super(name,month);this.sum=sum;this.rate=rate;}publicfloatgetSalary(intmonth){returnrate*sumsuper.getSalary(month);}}BasePlusSalesEmployee：SalesEmployee的子类，有固定底薪的销售人员，工资由底薪加上销售提成部分。属性：底薪。packageCompany;publicclassBasePlusSalesEmployeeextendsSalesEmployee{floatsalary;publicBasePlusSalesEmployee(Stringname,intmonth,floatsalary,floatsum,floatrate){super(name,month,sum,rate);this.salary=salary;}publicfloatsalary(intmonth){returnsalarysum*ratesuper.getSalary(month);}}测试类输出显示packageCompany;publicclassTest{publicstaticvoidmain(Stringargs[]){Employeea[]=newEmployee[4];a[0]=newSalariedEmployee("张三",4,4440);a[1]=newHourlyEmployee("李四",3,224,30);a[2]=newSalesEmployee("王五",7,50000,0.1f);a[3]=newBasePlusSalesEmployee("周六",12,2500,64500,0.1f);System.out.println("张三的工资为："a[0].getSalary(7));System.out.println("李四的工资为："a[1].getSalary(7));System.out.println("王五的工资为："a[2].getSalary(7));System.out.println("周六的工资为："a[3].getSalary(7));}}
