Answer to Question #237736 in Java | JSP | JSF for Eulanda

Question

The user must have the ability to search for a product. The user will select menu item
two (2), which will prompt the user to enter a product code. If a valid product is found in
the application, then display the product details to the user. If no valid product is found,
display an error message to the user that the product cannot be located.

Answer 1

import java.util.Scanner;
public class Main

    public static void Search(int[] arr, int k){    
        for(int i=0;i<arr.length;i++){

                break;
            }    
        }    
        System.out.println("The product is not found.");    
    }
	public static void main(String[] args) {
	    Scanner in=new Scanner(System.in);
	    System.out.println("Enter number of products: ");
	    int n=in.nextInt();
		Product [] p=new Product[n];
		
		for(int i=0;i<n;i++){
		    p[i].getData();
		}
		for(int i=0;i<n;i++){
