Question

Modify the program provided so that it can produce the Price and the Total with two digits after the decimal place. (note: Modify given program in a way that a beginner Java programmer would)

Do not use: import java.text.*;    & DecimalFormat f = new DecimalFormat("##.00");

Program Provided:

Expected:

/I Product 1 System.out.println("Enter info for Product 1"); System.out.print ("Product name: ") productNamescnr.next; System.out.print("Quantity:"); quantityProductscnr.nextInt); System.out.print ("Unit Price:") unitPricescnr.nextDouble); totalCost quantityProduct unitPrice; System.out.println(") Product 2 System.out.println("Enter info for Product 1"); System.out.print("Product name: ") productName2scnr.next); System.out-print("Quantity:") quantityProduct2·scnr.next Int(); System.out.print("Unit Price: ") unitPrice2scnr.nextDuble) totalCost quantityProduct2 unitPrice2; System.out.println("); // neccessary adjustments System.out.printf("n); System.out.printf("I %-les l %12s l %12s | %12s l ", "Product. "Qty", "Price", "Total"); System.out.printf(" System out printf(" %-10s X12s X12s %12s ", productName substring(0, 1) toUpperCase() System out printf(" %-10s X12s X12s $12n", productName2. substring(0, 1) tolpperCase() + productName toLoverCase().substring(1), quantityProduct, unitPrice, tota!Cost); + productName2.tolowerCase() substring(1), quantityProduct2, unitPrice2, tot alcost2);

Explanation / Answer

import java.util.*;

class products{

public static double roundOffToTwo(double val){

return (double) Math.round(val * 100) / 100;

}

public static void main(String srgs[]){

String productName,productName2;

int quantityProduct,quantityProduct2;

double unitPrice,unitPrice2,totalCost,totalCost2;

Scanner scnr=new Scanner(System.in);

System.out.println("Enter info for Product 1");

System.out.print("Product name: ");

productName = scnr.next();

System.out.print("Quantity: ");

quantityProduct = scnr.nextInt();

System.out.print("Unit Price: ");

unitPrice = scnr.nextDouble();

totalCost = quantityProduct * unitPrice;

System.out.println(" ");

System.out.println("Enter info for Product 2");

System.out.print("Product name: ");

productName2 = scnr.next();

System.out.print("Quantity: ");

quantityProduct2 = scnr.nextInt();

System.out.print("Unit Price: ");

unitPrice2 = scnr.nextDouble();

totalCost2 = quantityProduct2 * unitPrice2;

System.out.println(" ");

System.out.printf("----------------------------------------------------------- ");

System.out.printf("| %-10s | %12s | %12s | %12s | ","Product","Qty","Price","Total");

System.out.printf("----------------------------------------------------------- ");

System.out.printf("| %-10s | %12s | %12.2f | %12.2f | ",productName.substring(0,1).toUpperCase() + productName.toLowerCase().substring(1),quantityProduct,roundOffToTwo(unitPrice),roundOffToTwo(totalCost));

System.out.printf("| %-10s | %12s | %12.2f | %12.2f | ",productName2.substring(0,1).toUpperCase() + productName2.toLowerCase().substring(1),quantityProduct2,roundOffToTwo(unitPrice2),roundOffToTwo(totalCost2));

System.out.printf("----------------------------------------------------------- ");

}

}
