Answer:
The code will give an error that is "At least one public class is required in main file".
Explanation:
In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:
Program:
import java.util.HashSet; //import package
public class A //define class as public.
{
public static void main(String[ ] args) //define main method.
{
HashSet set = new HashSet(); //creating hashset object.
set.add("A"); //add alphabet in hashset
set.add("B"); //add alphabet in hashset
set.add("C"); //add alphabet in hashset
System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.
}
}
Output:
Size of HashSet is : 3
Explanation of the program:
- In the above program, we define a public class that is "A" and inside the class, we define the main method.
- Inside the main method, we create a HashSet class object that is "set".
- To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
The engineer will need to set the distance to 130 for the static link so that it becomes a floating static route.
<h3>What is Floating static routes?</h3>
This is known to be a static routes that is said to have a kind of administrative distance that is also known to be bigger than the administrative distance of any other static route or dynamic routes.
Note that the value 130 stands for the next most logical value, nd as such it is to know that the right route comes first in the steps for administrative distance.

Group Policy, change the setting "Turn off the upgrade to the latest version of Windows through Windows Update," which can be found in Computer Configuration / Administrative Templates / Windows Components / Windows Update.
Doing so sets the registry value described in the rest of this step. Note that for Home versions of Windows 7 and 8.1, where the Group Policy editor is not available, editing the registry is the only option.
To make this change with Regedit, navigate to the following key.
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
Important: If that key doesn't exist, you'll need to create it.
Create a DWORD value called DisableOSUpgrade and set it to 1. (If that sentence makes no sense, you probably shouldn't be using Regedit.)
