Answer:
import java.util.Scanner;
public class Supermarket
{
public static void main (String[] args)
{
String item;
double pounds, ounces, price,
total, unit;
Scanner scn = new Scanner(System.in);
System.out.print("Please enter the name of item ");
item = scn.nextLine();
System.out.print("Please enter the price of " + "the item per pound : ");
price = scn.nextDouble();
System.out.print("Enter the weight of " + "the item in pounds and " + "ounces respectively : ");
pounds = scn.nextDouble();
ounces = scn.nextDouble();
unit = price/16;
total = price * (pounds + ounces/16);
System.out.print("The unit price of " + "the products sold is : " + unit);
System.out.print("\nThe total cost of the " + "amount purchased is : " + total);
}
}
Explanation:
- Ask the user to enter the price of the item and the weight.
- Calculate the unit and the total price.
- Display the unit and the total price.

Answer:
Explanation:
In data communications, a protocol is <em>connectionless </em>if it describes communication between two devices in a network without first establishing or verifying establishment of some link (connection) between the two devices. In a connectionless protocol, data are exchanged between processes or devices without a prior check of whether the processes are ready to transmit data or not. In this type of protocol, there's no verification put in place to remember if these processes were or are in communication. Connectionless protocols are also called stateless protocols. Because connectionless protocol cannot be relied upon due to its lack of delivery-assurance policy, it is sometimes referred to as <em>unreliable protocol</em>. In other words, delivery of data packets is not guaranteed. An example of a connectionless protocol is the UDP (User Datagram Protocol).
However, if the protocol defines some checks to ascertain that there is first a connection between two communicating processes before beginning transmission, then, the protocol is <em>connection-oriented. </em>An example of this is the TCP (Transmission Control Protocol). Connection-oriented protocols are reliable since they ensure connection be made between processes before transmitting data packets.
A typical application of a connectionless/unreliable protocol is in the streaming of real time videos or voice communication where packets of data could be dropped and not resent.
An example of the connection-oriented/reliable protocol is analogous to making a telephone call where data packets (voice messages) are not sent until the receiver on the other end makes a connection.
