【问题描述】 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。 【输入形式】 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） 【输出形式】 分别输出电动汽车、电脑充电、放电信息 【样例输入】 Dongfeng 36 100 HP 65 9.5 【样例输出】 name:Dongfeng vehicle,I am charging... input voltage:220V charging voltage:36.0V name:Dongfeng vehicle,I will discharge 100 degrees,I am discharging... name:HP notebook,I am charging... input voltage:220V charging power:65W name:HP notebook,I will discharge. Discharge voltage:9.5V,I am discharging...

电源接口的代码如下：

public interface PowerInterface {
    int INPUT_VOLTAGE = 220;

    void addPower();

    void discharge();
}

电动汽车类的代码如下：

public class ElectricVehicle implements PowerInterface {
    private String name;
    private double chargingVoltage;
    private int dischargeAmount;

    public ElectricVehicle(String name, double chargingVoltage, int dischargeAmount) {
        this.name = name;
        this.chargingVoltage = chargingVoltage;
        this.dischargeAmount = dischargeAmount;
    }

    public void addPower() {
        System.out.println("name:" + name + " vehicle,I am charging... input voltage:" + INPUT_VOLTAGE + "V charging voltage:" + chargingVoltage + "V");
    }

    public void discharge() {
        System.out.println("name:" + name + " vehicle,I will discharge " + dischargeAmount + " degrees,I am discharging...");
    }

    // 省略基本的输入输出方法
}

电脑类的代码如下：

public class Notebook implements PowerInterface {
    private String name;
    private int chargingPower;
    private double dischargeVoltage;

    public Notebook(String name, int chargingPower, double dischargeVoltage) {
        this.name = name;
        this.chargingPower = chargingPower;
        this.dischargeVoltage = dischargeVoltage;
    }

    public void addPower() {
        System.out.println("name:" + name + " notebook,I am charging... input voltage:" + INPUT_VOLTAGE + "V charging power:" + chargingPower + "W");
    }

    public void discharge() {
        System.out.println("name:" + name + " notebook,will discharge. Discharge voltage:" + dischargeVoltage + "V,I am discharging...");
    }

    // 省略基本的输入输出方法
}

测试类的代码如下：

import java.util.Scanner;

public class Test {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // 创建电动汽车实例并调用充电和放电方法
        String evName = scanner.next();
        double evChargingVoltage = scanner.nextDouble();
        int evDischargeAmount = scanner.nextInt();
        ElectricVehicle electricVehicle = new ElectricVehicle(evName, evChargingVoltage, evDischargeAmount);
        electricVehicle.addPower();
        electricVehicle.discharge();

        // 创建电脑实例并调用充电和放电方法
        String notebookName = scanner.next();
        int notebookChargingPower = scanner.nextInt();
        double notebookDischargeVoltage = scanner.nextDouble();
        Notebook notebook = new Notebook(notebookName, notebookChargingPower, notebookDischargeVoltage);
        notebook.addPower();
        notebook.discharge();
    }
}

输入样例：

Dongfeng 36 100
HP 65 9.5

输出样例：

name:Dongfeng vehicle,I am charging... input voltage:220V charging voltage:36.0V
name:Dongfeng vehicle,I will discharge 100 degrees,I am discharging...
name:HP notebook,I am charging... input voltage:220V charging power:65W
name:HP notebook,will discharge. Discharge voltage:9.5V,I am discharging...
