Question

In Java with comments.

Write a program that computes the cost of flowers sold at a flower stand. Five kinds of flowers—petunia, pansy, rose, violet, and carnation— are stocked and cost, respectively, 50¢, 75¢, $1.50, 50¢, and 80¢ per flower. Create an array of strings that holds the names of these flowers. Create another array that holds the cost of each corresponding flower. Your program should read the name of a flower and the quantity desired by a customer. Locate the flower in the name array and use that index to find the cost per stem in the cost array. Compute and print the total cost of the sale.

Expected output: "The cost of 10 pansys is $7.5" or "The cost of 6 roses is $9.0" or "The cost of 2 violets is $1.0"

Answer 1

Program:

import java.util.*;

class ComputeCost
{
public static void main(String args[])
{
String flowers[]={"petunia", "pansy", "rose", "violet", "carnation"};
double cost[]={50,75,1.50,50,80};
String nameFlower;
int quantity;
double totalCost;
Scanner input=new Scanner(System.in);

System.out.println("\nThe Five Flowers and their costs: ");
System.out.println("\nFlowers\t\tCost");
System.out.println("-------------------------------");

for(int i=0;i<flowers.length;i++)
{
if(i==4)
{
System.out.println(flowers[i]+"\t"+cost[i]);
}
else
{
System.out.println(flowers[i]+"\t\t"+cost[i]);
}
}

System.out.println("\n");
System.out.print("Enter the name of a flower: ");
nameFlower=input.next();

int index=-1;

for(int i=0;i<flowers.length;i++)
{
if(flowers[i].equalsIgnoreCase(nameFlower))
{
index=i;
}
}
if(index==-1)
{
System.out.println("\n"+nameFlower+" is not in the list!!\n");
}
else
{

System.out.print("\nEnter the quantity: ");
quantity=input.nextInt();

if(index==2) //The cost of rose is in dollar
{
totalCost=quantity * cost[index];
System.out.println("\nThe cost of "+quantity+" "+nameFlower+"s is $"+totalCost+"\n");
}
else //Cost is in Cents
{
totalCost=quantity * cost[index];

System.out.println("\nThe cost of "+quantity+" "+nameFlower+"s is $"+totalCost/100+"\n");
}
}
}
}

Output:
