Answer to Question #239036 in Java | JSP | JSF for Jaden

Question

1. In your solution, you must create a class called Products, which will contain all your working
methods.
2. This class will, as a minimum, contain the following methods, but you are encouraged to
add more methods:
• SearchProduct();
• SaveProduct();
• UpdateProduct();
• DeleteProduct();
• DisplayMenu();
• CaptureProduct();
• ExitApplication();
3. Finally, create a main class to run your application

Answer 1

import java.util.ArrayList;


public class Products {
	private int price;
	private String productsId;
	private ArrayList<Products> products;


	public Products() {


	}


	public Products(int price, String productsId) {
		this.price = price;
		this.productsId = productsId;
	}


	public int getPrice() {
		return price;
	}


	public void setPrice(int price) {
		this.price = price;
	}


	public String getProductsId() {
		return productsId;
	}


	public void setProductsId(String productsId) {
		this.productsId = productsId;
	}


	public ArrayList<Products> getProducts() {
		return products;
	}


	public void setProducts(ArrayList<Products> products) {
		this.products = products;
	}


	@Override
	public String toString() {
		return "Products [price=" + price + ", productsId=" + productsId + ", products=" + products + "]";
	}


	public void searchProduct(Products product) {
		for (Products pr : products) {
			if (product.productsId.equals(pr.productsId)) {
				System.out.println(product.toString());
			} else if (!(product.productsId.equals(pr.productsId))) {
				System.out.println("No such product!");
			}
		}
	}


	public void saveProduct(Products product) {
		for (Products pr : products) {
			if (product.productsId.equals(pr.productsId)) {
				System.out.println("Product with id: " + product.productsId + " already consist!");
			} else if (!(product.productsId.equals(pr.productsId))) {
				products.add(product);
				System.out.println("Product added.");
			}
		}
	}


	public void updateProduct(Products product, int price) {
		for (Products pr : products) {
			if (product.productsId.equals(pr.productsId)) {
				pr.setPrice(price);
				System.out.println("Product with id: " + product.productsId + " changed pice to: " + price);
			}
		}
	}


	public void deleteProduct(Products product) {
		for (Products pr : products) {
			if (product.productsId.equals(pr.productsId)) {
				products.remove(product);
				System.out.println("Product with id: " + product.productsId + " delated.");
			} else if (!(product.productsId.equals(pr.productsId))) {
				System.out.println("No such product!");
			}
		}
	}


	public void displayMenu() {
		for (Products pr : products) {
			System.out.println(pr.toString());
		}
	}


	public void captureProduct(Products product) {
		for (Products pr : products) {
			if (product.productsId.equals(pr.productsId)) {
				products.remove(product);
				System.out.println("Product with id: " + product.productsId + " captured.");
			} else if (!(product.productsId.equals(pr.productsId))) {
				System.out.println("No such product!");
			}
		}
	}
	public void exitAplication() {
		System.out.println("Exit.");
	}
}

public class Main {


	public static void main(String[] args) {
		Products products = new Products();
		products.searchProduct(products);
		products.saveProduct(products);
		products.updateProduct(products, 23);
		products.deleteProduct(products);
		products.displayMenu();
		products.captureProduct(products);
		products.exitAplication();


	}
