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:
offline backup solution
Explanation:
In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.
Answer:
int i = 0; i < names.size(); i++
Explanation:
The ArrayList must be read in the forward direction, and it is going to start from 0 certainly. Also, the iteration is going to end when i is exactly one less than the size of the ArrayList. And this is possible only if we choose the option mentioned in the Answer section. In this, i starts from 0 and iterates till i is one less than name.size() which is the size of the ArrayList.
They would all work as they can all run on servers and be set up as networks. Microsoft is not an operating system it is a company that rights the windows operating system.
