Question

35 POINTS
In Java PLS
This program is the beginning of an automated order machine. You are programming the piece that gets the number of the order from the label sent to you by the ordering machine.

The ordering machine is simulated with user input. It sends a full label, such as “3. Veggie Burger”.



Fill in the missing code
Your task is to get the number out of the string. To do this, you need to isolate the number by using substring. Then use Integer.valueOf, a static method of Integer that takes a String and returns the integer value contained in the String.

The final program should look something like this

1. Hamburger
2. Cheeseburger
3. Veggie Burger
4. Nachos
5. Hot Dog

Enter label:
5. Hot Dog
Customer ordered number 5

This is the code given:
import java.util.Scanner;

public class PickupWindow
{
public static void main(String[] args)
{
// Create scanner object
Scanner input = new Scanner(System.in);

// Display menu
String menu = "1. Hamburger\n2. Cheeseburger\n3. Veggie Burger\n4. Nachos\n5. Hot Dog\n";

System.out.println(menu);

// Get customer order
System.out.println("Enter label: ");
String customerOrder = input.nextLine();

// Use substring to get the first character (the number)
String combo =

// Create an Integer object by using the static
// method Integer.valueOf(someString)
// to turn the string into an Integer

Integer comboNumber =

// Print out what the customer ordered
System.out.println("Customer ordered number "


}
}

Answer 1

Answer:

Complete the program as follows:

1. Replace

String combo =

with

String combo = customerOrder.substring(0);

2. Replace

Integer comboNumber =

with

Integer comboNumber = Integer.parseInt(combo);

Explanation:

Required

Fill in the missing codes

From the code given, there are only two gaps to be filled and they are:

1. String combo =

2. Integer comboNumber =

1. String combo =

The first is to get the first index of customerOrder using substring.

The syntax of this is:

variable.substring(0);

In this case, the syntax will be replaced with:

String combo = customerOrder.substring(0);

Where customerOrder represents the string variables

2. Integer comboNumber =

This is to convert combo from string to integer using parseInt

This is done as follows:

Integer comboNumber = Integer.parseInt(combo);
