import com.sun.org.apache.xalan.internal.xsltc.compiler.sym;


class Item {

	public Item() {
	}


	public Item(String name, double price) {
		this.name = name;
		this.price = price;
	}


	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}


	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}


	/**
	 * @return the price
	 */
	public double getPrice() {
		return price;
	}


	/**
	 * @param price the price to set
	 */
	public void setPrice(double price) {
		this.price = price;
	}


}


class App {


	public static void main(String[] args) {
		Scanner keyBoard = new Scanner(System.in);
		Item items[] = new Item[5];
		double totalPrice = 0;
		// 1. Read the name and price of five items as input.
		for (int i = 0; i < 5; i++) {
			System.out.print("Enter the name of the item " + (i + 1) + ": ");
			String name = keyBoard.nextLine();
			System.out.print("Enter the price of the item " + (i + 1) + ": ");
			double price = keyBoard.nextDouble();
			// 2. Calculate the total price for the items.
			totalPrice += price;
			items[i] = new Item(name, price);
			keyBoard.nextLine();
		}
		// 3. Display all the item names and prices.
		System.out.printf("%-15s%-10s\n", "Name", "Price");
		for (int i = 0; i < 5; i++) {
			System.out.printf("%-15s%-10.2f\n", items[i].getName(), items[i].getPrice());
		}
		// 4. Display the total due for all items.


		System.out.println("The total due for all items: " + totalPrice);
		keyBoard.close();
