1.Given the below java code

a.Explain what you think the program does.(Hint! Run and test)

This program allows you to calculate the price of coffee based on several information, such as the number of coffee bags and the weight of the bag, and then the total price is displayed with tax.

The sequence of operations in the program is as follows:

First, the user is displayed with a welcome message and asked to enter the number of bags and the weight of each bag by using the Scanner object to read the entry.

Secondly, additional information such as the date and time of the current operation is displayed using the java.time.LocalDateTime library.

Third, the total price of the bags is calculated based on the number of bags, the weight of the bag and the price per kilogram. The tax is then calculated and added to the total price.

Finally, the final total price of the coffee bags with tax is printed

b.Name one object, one parameter, and one local variable

Object: sc (It is an instance of the Scanner class)

Parameter: String ar[] (part of the main method signature)

local variable: total

1.In the main method,

a.Create a new object called store1 of the CoffeeStore class

b.Send object store1 as an argument in System.out.println statement.

import java.time.LocalDateTime;

import java.util.Scanner;

public class CoffeeStoreMain {

public static void main(String ar[])

{

int numOfBags;

float bagWeight;

float tax =15;

int pricePerKg =1;

Scanner sc =new Scanner(System.in);

System.out.print("Welcome to the Coffee Store\nEnter No of Bags:");

numOfBags = sc.nextInt();

System.out.print("Enter Bags Weight kg:");

bagWeight = sc.nextFloat();

System.out.println("-------------------------\n");

System.out.println("\n COFFEE STORE \n\n"

+"Number of Bags: "+ numOfBags

+"\nBag Weight (kg): "+ bagWeight

+"\nTax: S.R. "+tax

+"\n"+(LocalDateTime.now())

+"\n\n==========================\n");

float total = numOfBags * pricePerKg * bagWeight;

total = total+(tax/100*total);

System.out.println("TOTAL with Tax: S.R. " + total+"\n");

}

}
