Answer:
import java.util.Scanner;
public class HelloIDE
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter your name: ");
String name = input.nextLine();
name = name.trim();
if(name.equals(""))
name = "stranger";
System.out.println("Hello, " + name + "!");
}
}
Explanation:
import the Scanner class to be able to get input from the user
Create an object of the Scanner class called input
Ask the user to enter the name and set it to the name
Trim the name using trim() method, removes the whitespaces from the string
Check the name. If name is equal to "", set the name as stranger. This way if the name is empty, or just contains whitespaces or if name is not given, name will be set as stranger.
Print the name in required format
Answer:
Category 5 (Cat 5) twisted pair is the least quality twisted pair wire that should be used.
Explanation:
The reason is as follows:
- Category 1 twisted pair is not suitable for transmitting data but comes in handy for telephone communications. Hence, it should not be used in a data/voice application.
- Category 2 twisted pair is suitable for data transmission, however, it can only transmit at 4Mbps which is very slow. Hence, it should not be used in a data/voice application.
- Category 3 twisted pair can transmit data with speed reaching 10Mbps which is slow for voice/data communication.
- Category 4 twisted pair can transmit data with speed reaching 16Mbps and is used in token ring networks. It is slow for communicating in a voice/data application.
- Category 5 twisted pair is the least qualified to be used in a voice/data application because it can transmit data at speeds that reach 100Mbps.
Hence, Cat 5 or Category 5 twisted pair is the least quality twisted pair that should be used in a data/voice application.
