Question by Jaix: Compose a method in Java to get a product sales report system that computes and prints the discount for any product?
I’m new to java but i’m sorta stuck! The plan should choose from four items. Based on the quantity ordered,Office Standard 2010, if the quantity is 20 )

discount = 15 / 100 * itemPrice;
else if( order = 11 )

discount = 10 / 100 * itemPrice;
else if( order = 6 )

discount = 5 / 10 * itemPrice;
else

discount = 0;
return low cost;
}
public double calculateAmount()
double amount;
amount = itemPrice – discount;
return amount;
}
The main method code:
/*

package salesrecord;
import java.util.Scanner;
/**

public class SalesRecordTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
int itemNumber = 0;
int quantity;
String itemName = “”;
double price = 0;
Scanner input = new Scanner( System.in );
System.out.println( “CURRENT ITEMS IN STOCK ARE LISTED BELOW:\n” );
System.out.println( “Item Number\t Item Name” );
System.out.println( “1)\t\t Dell 15\” Laptop\n2)\t\t HP Mini NoteBook\n3)\t\t Sony VIAO 12\” Tablet\n4)\t\t Apple MacBook Air” );
System.out.print( “\nEnter Desired Item Number: ” );
itemNumber = input.nextInt();
if( itemNumber == 1 )

price = 500;
itemName = “Dell Laptop”;
System.out.println( “You selected Dell 15\” Laptop\n” );
else if( itemNumber == 2 )

price = 400;
itemName = “HP NoteBook”;
System.out.println( “You selected HP Mini NoteBook\n” );
else if( itemNumber == 3 )

price = 800;
itemName = “Sony Tablet”;
System.out.println( “You selected Sony VIAO 12\” Tablet\n” );
else if( itemNumber == 4 )

price = 1300;
itemName = “MacBook Air”;
System.out.println( “You selected Apple MacBook Air\n” );
else

System.out.println( “Invalid Item Number Entered!” );
Program.out.print( “Enter Desired Quantity: ” );
quantity = input.nextInt();
SalesRecord mySalesRecord = new SalesRecord( price );
Program.out.println();
Method.out.println( “ITEM NUMBER\tITEM NAME\tQUANTITY\tPRICE ($ )\tDISCOUNT ($ )\tAMOUNT ($ )\n” );
Method.out.printf( “%d\t\t%s\t%d\t\t%.2f\t%.2f\t\t%.2f\n\n”, itemNumber, itemName, quantity, mySalesRecord.getItemPrice(),
mySalesRecord.calculateDiscount( quantity ),Office Pro Plus 2010 Key, mySalesRecord.calculateAmount() );
Technique.out.println( “Thank you for Shopping with us!” );
}
}

Answer by Sayee
First, Thanks for the question,Office Professional Plus 2007! It took about 10 min before I spotted the mistake!
when using double
don’t do low cost = 5 / 10 * itemPrice;
USE low cost = 5.0 / 10.0 * itemPrice;
change all numbers with an extra .0 in all the calculation lines similar to above and it should work fine,Purchase Windows 7!
Hope it helps.
