Question

"using eclipse "

Given the structure in Figurefor the Interface and the classes, write ajava program that implements the given structure. Add a driver,create atleast one object of each class and use the Interfaceto reference them. Print all related information for each object bycalling methods GetInfo() and GetValue().

Method Description:

GetInfo(): Will print allrelated data members for any class.

GetValue():

Constructors(): Must setall related data members.

OutputSample:

Object 1

Type: Invoice

Quantity: 10

Price: 550

Calculated Value: 5500

-----------------------------

Object 2

Type: Benz

Production Year: 2005

Used Years: 4

Original Price: 12500

Calculated Value: 10000

Explanation / Answer

/* save the below code in "Driver.java" compile using "javac Driver.java" reun using "java Driver" */ import java.io.*; interface Information{ public void getInfo(); public void getValue(); } class Invoice implements Information {    public int quantity;    public double price;       public Invoice(int quantity, double price)    {        this.quantity = quantity;        this. price = price;    }       public void setQuantity(int quantity)    {        this.quantity = quantity;    }    public void setPrice (double price)    {        this.price = price;    }       public int getQuantity()    {        return quantity;    }          public double getPrice()    {        return price;    }       public void getInfo()    {        System.out.println("Type: " +"Invoice");        System.out.println("Quantity:" + quantity);        System.out.println("Price:" +price);    }       public void getValue()    {        System.out.println("Calculated Value: " + (quantity* price));    } }//end of Invoice class class Vehicle implements Information {    public String type;    public int productionYear;    public int usedYears;    public double originalPrice;       public Vehicle( String type, intproductionYear, int usedYears, double originalPrice)    {        this.type =type;        this.productionYear=productionYear;        this.usedYears =usedYears;        this.originalPrice = originalPrice;    }       public void setType(String type)    {        this.type = type;    }       public void setProductionYear(intproductionYear)    {        this.productionYear =productionYear ;    }       public void setUsedYears(int usedYears)    {        this.usedYears =usedYears ;    }       public void setOriginalPrice (doubleoriginalPrice )    {        this.originalPrice   = originalPrice  ;    }       public String getType()    {        return type;    }       public int getProductionYear()    {        return productionYear;    }    public int getUsedYears()    {        return usedYears ;    }    public double getOriginalPrice()    {        return originalPrice ;    }       public void getInfo()    {        System.out.println("Type: " +type);        System.out.println("productionYear:" + productionYear);        System.out.println("usedYears: " + usedYears);        System.out.println("originalPrice: " + originalPrice);    }       public void getValue()    {        System.out.println("Calculated Value: " + (originalPrice - ( (0.05* originalPrice) * usedYears)));    } }//end of Vehicle class public class Driver { public static void main(String[] args){ Invoice in = new Invoice(10, 550); System.out.println("---------------------------------------------------"); System.out.println("Object 1"); in.getInfo(); in.getValue(); System.out.println("---------------------------------------------------"); Vehicle vh = new Vehicle("Benz" , 2005, 4, 12500); System.out.println("Object 2"); vh.getInfo(); vh.getValue(); }//end of main }//end of class Driver
