1.机器人类及其子类

设计一个机器人的抽象类，具有质量（double）、名字（String）等属性；具有设置属性值方法和获得并打印属性值的方法，还有一个运动的抽象方法move()。设计电动汽车类和飞行器类，这两个类继承机器人抽象类，实现抽象方法，并在抽象方法中打印输出“我是电动汽车，我在地上跑！”（电动汽车类），以及“我是飞行器，我在天上飞！”（飞行器类）。设计测试类，分别生成电动汽车和飞行器的实例，分别按顺序输入名字和质量，并调用获得名字的方法输出名字，调用抽象方法打印对应信息。
输入描述：分两行输入电动汽车信息和飞行器信息
输出描述：分别输出电动汽车名字、运动信息。

package rotdome;import java.util.Scanner;public class RotDome {public static void main(String[] args) {// TODO Auto-generated method stubScanner in = new Scanner(System.in);String name = in.next();double weight = in.nextDouble();String name1 = in.next();double weight1 = in.nextDouble();Rot car1 = new Car();car1.setName(name);car1.setQuality(weight);System.out.println(car1.toSting());car1.move();Rot plan1 = new Plan();plan1.setName(name1);plan1.setQuality(weight1);System.out.println(plan1.toSting());plan1.move();in.close();}}abstract class Rot {protected double weight;protected String name;public double getQuality() {return weight;}public void setQuality(double quality) {this.weight = quality;}public String getName() {return name;}public void setName(String name) {this.name = name;}abstract public void move();public String toSting() {return "name:" + name + " weight:" + weight + "KG";}
}class Car extends Rot {public void move() {System.out.println("I am automobile,I am running on the ground!");}
}class Plan extends Rot {public void move() {System.out.println("I am aircraft,I am flying in the sky!");}
}

2.创建电源接口及对子类进行充放电

一个电源接口，有一个输入电压的整型常量，值为220；设计两个抽象方法：1）充电方法，addPower()；2）放电方法，discharge()。
设计电动汽车类，设置名字（String）、充电电压（double）和放电量（int）属性，实现构造方法、基本的输入输出方法和电源接口，实现充电方法，输出：
name:XXX vehicle, I am charging…
input voltage:XXX charging voltage:XXX”。
实现放电方法，输出：
name:XXX vehicle, I will discharge XXX degrees, I am discharging…

设计电脑类，设置名字（String）、充电功率（int）和放电电压（double）属性，实现构造方法、基本的输入输出方法和电源接口。实现充电方法，输出：
name:XXX notebook, I am charging…
input voltage:XXXV charging power:XXW
实现放电方法，输出：
name:XXX notebook, will discharge.
Discharge voltage:XXXV,I am discharging…
设计主测试类，输入名字、充电电压和放电量），生成电动汽车的实例，依次调用充电方法和放电方法。输入名字、充电功率和放电电压，生成电脑的实例，依次调用充电方法和放电方法。

输入描述
第一行输入电动汽车信息（名字 充电电压 放电量）
第二行输入电脑信息（名字 充电功率 放电电压）
输出描述
分别输出电动汽车、电脑充电、放电信息

package plugDome;import java.util.Scanner;public class PlugDome {public static void main(String[] args) {// TODO Auto-generated method stubScanner in = new Scanner(System.in);//电动汽车类输入String name = in.next();double avoltage = in.nextDouble();int dvoltage = in.nextInt();//电脑类输入String name1 = in.next();int chargingpower = in.nextInt();double dvoltage1 = in.nextDouble();Plug E1 = new ElectricVehicle(name,avoltage,dvoltage);//new一个ElectricVehicle对象E1Plug C1 = new Computer(name1,chargingpower,dvoltage1);//同理E1.addPower();E1.discharge();C1.addPower();C1.discharge();in.close();}}
interface Plug{int Voltage = 220;public void addPower();//充电——抽象方法public void discharge();//放电——抽象方法
}
class ElectricVehicle implements Plug{private String name;private double avoltage;private int dvoltage;public ElectricVehicle(String name,double avoltage,int dvoltage) {this.name = name;this.avoltage = avoltage;this.dvoltage = dvoltage;}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getAvoltage() {return avoltage;}public void setAvoltage(double avoltage) {this.avoltage = avoltage;}public int getDvoltage() {return dvoltage;}public void setDvoltage(int dvoltage) {this.dvoltage = dvoltage;}//实现接口中的抽象方法public void addPower() {System.out.println("name:"+name+" vehicle,I am charging..."+"\n"+"input voltage:"+Voltage+"V charging voltage:"+avoltage+"V");}public void discharge() {System.out.println("name:"+name+" vehicle,I will discharge "+dvoltage+" degrees,I am discharging...");}
}
class Computer implements Plug{private String name;private int chargingpower;private double dvoltage;public Computer(String name,int chargingpower,double dvoltage) {this.name = name;this.chargingpower = chargingpower;this.dvoltage = dvoltage;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getChargingpower() {return chargingpower;}public void setChargingpower(int chargingpower) {this.chargingpower = chargingpower;}public double getDvoltage() {return dvoltage;}public void setDvoltage(double dvoltage) {this.dvoltage = dvoltage;}//实现接口中的抽象方法public void addPower() {System.out.println("name:"+name+" notebook,I am charging..."+"\n"+"input voltage:"+Voltage+"V charging power:"+chargingpower+"W");}public void discharge() {System.out.println("name:"+name+" notebook,I will discharge."+"\n"+"Discharge voltage:"+dvoltage+"V,I am discharging...");}
}
