Question

How to construct a grocery list using arrays that prints out the price, and quanity of the item? I am really stuck, I am in Java 1.

Answer 1

Program:

package HomeworkLib.answers;

import java.util.Scanner;
public class GroceryList {
    public static void main(String args[]){
        // arrays to store the item name, price and quantity
        String[] item;
        float[] price, quantity;
        int n;
        
        // creating scanner object to get input from user
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the number of items: ");
        // storing number of items
        n = sc.nextInt();
        // creating arrays of specified size
        item = new String[n];
        price = new float[n];
        quantity = new float[n];
        
        // loop to enter values in the arrays
        for(int i = 0; i < n; i++){
            System.out.println("Enter the item its price and quantity: ");
            item[i] = sc.next();
            price[i] = sc.nextFloat();
            quantity[i] = sc.nextFloat();
        }
        
        System.out.println("GROCERY LIST: ");
        System.out.println("Item:\t\tPrice:\t\tQuantity:");
        
        // printing the arrays
        for(int i = 0; i < n; i++){
            System.out.println(item[i] + "\t\t" + price[i] + "\t\t" + quantity[i]);
        }
    }
}

Output:

Enter the number of items:
3
Enter the item its price and quantity:
Milk
10.2
6
Enter the item its price and quantity:
Eggs
7
12
Enter the item its price and quantity:
