Explanation:
The following code is written in Java, it prompts the user to enter 10 integers and saves them to an ArrayList. Then it prompts for 5 strings and saves them to another ArrayList. Then, it calls the sort method and adds the lists as parameters. Finally, it prints out both lists completely sorted in ascending order.
import java.util.ArrayList;
import java.util.Scanner;
class Division{
public static double division(double a, double b) throws Exception {
if(b == 0)
//throw new Exception("Invalid number.");
return (a / b);
return a / b;
}
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
ArrayList<Integer> mylist2 = new ArrayList<>();
for (int x = 0; x < 10; x++) {
System.out.println("Please Enter a Number: ");
int number = in.nextInt();
mylist2.add(number);
}
ArrayList<String> mylist = new ArrayList<>();
for (int x = 0; x < 5; x++) {
System.out.println("Please Enter a Word: ");
String word = in.nextLine();
mylist.add(word);
}
sort(mylist);
sort(mylist2);
for (String x: mylist) {
System.out.print(x + ", ");
}
System.out.println("");
for (int x: mylist2) {
System.out.print(x + ", ");
}
}
public static <E extends Comparable<E>> ArrayList<E> sort(ArrayList<E> list) {
E temp;
if (list.size()>1) // check if the number of orders is larger than 1
{
for (int x=0; x<list.size(); x++) // bubble sort outer loop
{
for (int i=0; i < list.size() - x - 1; i++) {
if (list.get(i).compareTo(list.get(i+1)) > 0)
{
temp = list.get(i);
list.set(i,list.get(i+1) );
list.set(i+1, temp);
}
}
}
}
return list;
}}
In the network constructed, we need to use 3 switches to be able to connect a single client PC to the single server. Therefore:
- Connect server to switch 1 (225 m)
- Connect switch 1 to switch 2 (225 m)
- Connect switch 2 to switch 3 (225 m)
- Connect switch 3 to client PC (225 m)
The maximum distance for ethernet connection is known to be about 100 meters and it is one that is often used in the transmission speeds.
Note that when one has added to the network switches, the distance need to be increased to about 200 meters and thus about 900 meters of distance need to exist between the client PC and the server.
The Ethernet network need to be designed as:
Connect server to switch 1 (225 m)
Connect switch 1 to switch 2 (225 m)
Connect switch 2 to switch 3 (225 m)
Connect switch 3 to client PC (225 m)
Note that Total distance covered = 225 + 225 + 225 + 225
= 900 meters
Therefore, In the network constructed, we need to use 3 switches to be able to connect a single client PC to the single server.
