Create a brief program that demonstrates use of a Java exception. For example, you could use InputMismatchException and ask the user to input an integer and show that the program executes correctly if they enter an integer and also show that the exception is thrown and a proper error message is displayed to the user if they input a string of letters. You may want to try it with and without a try catch block for practice, but either one will be sufficient for credit.
Answers
Answer:
Here is the program that demonstrates the use of JAVA exception:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main method
Scanner input = new java.util.Scanner(System.in); //creates Scanner class object to accept input from user
int number1 = 0; //stores the first integer value
int number2 = 0; //stores the second integer value
while(true) { //keeps looping until user enters integer value
System.out.println("Enter 2 integers to perform addition: "); //prompts user to enter two integer values
try { //defines a chunk of code to check for errors
number1 = input.nextInt(); //reads input integer 1
number2 = input.nextInt(); //reads input integer 2
break; }
catch (java.util.InputMismatchException e) { // defines a code chunk to execute if an error occurs in the try code chunk
System.out.println("Input must be an integer "); //displays this message if user enters anything other than an integer value
input.nextLine(); } } // reads input from user again until user enters both integer type values
System.out.println("The sum is: " + (number1+number2)); } } //if user enters 2 integers then computes and displays the sum of two integer values
Explanation:
The program uses InputMismatchException exception and asks the user to input two integers and computes the sum of two integers if user enters integers otherwise an exception InputMismatchException is thrown and a error message Input must be an integer is displayed to the user if they input a string of letters instead o f integer values. Here while loop is used which keeps executing until user enters both the integer values. After the user enters correct values, the sum of the two integers are computed and result is displayed on output screen. The screenshot of program and its output is attached.
Another program asks the user to input an integer and the program executes correctly if they enter an integer but exception InputMismatchException is thrown with an error message that is is displayed to the user if they input a string of letters. Here is the program:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new java.util.Scanner(System.in);
int number1 = 0;
while(true) {
System.out.println("Enter an integer value: ");
try {
number1 = input.nextInt();
break; }
catch (java.util.InputMismatchException e) {
System.out.println("Input must be an integer ");
input.nextLine(); } }
System.out.println("The program executed correctly!"); } }

You are a Network administrator for a company whose IP address is 199.199.10.0/24. Your company has two departments. Research needs 13 hosts and Marketing needs 31 hosts. Using VLSM; what is the network address of the second subnet?
Answers
Answer:
Explanation:
VLSM is Variable Fixed Length Subnet Mask which creates subnets with varying sizes with a variable number of hosts.
Arrange the different subnets with descending number of hosts required. So the first subnet will be for Marketing and the second will be for Research. The second subnet will have the second higher IP available which is 199.199.10.0/26. It has 64 IP addresses that can be assigned to 13 hosts required by Research.

From the statement, we have the following loop conditions:
h = 1; h <= 12, m = 0; m <= 59 and s = 0; s <= 59
The above means that:
h = 12 --- the outer loop will be executed 12 timesm = 60 --- the middle loop will be executed 60 timess = 60 --- the inner loop will be executed 60 timesSo, the number of times the nested loop will be executed is:

Assignment 5B : Maze Game! 2D Arrays can be used to store and represent information
about video game levels or boards. You will use this knowledge to make an interactive game where players attempt to move through a maze. You will start by creating a pre-defined 2D array with the following values:
{"_","X","_","X","X"}
{"_","X","_","X","W"}
{"_","_","_","X","_"}
{"X","X","_","_","_"}
{"_","_","_","X","X"}
You will then set the player (represented by "O") at index 0, 0 of the array, the top-left
corner of the maze. You will use a loop to repeatedly prompt the user to enter a
direction ("Left", "Right", "Up", or "Down"). Based on these directions, you will try to
move the player.
• If the location is valid (represented by "_"), you will move the player there
• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, you
will inform the player and prompt them to enter another direction
• If the location is a wall (represented by "X"), you will tell the user they hit a wall
and the game is over.
If the player did not lose, you will print out the current state of the map and ask them for
a new direction. You will keep doing this until they lose or they reach the end
(represented by the "W").

Discuss how the use of standard web component layouts and templates influences the visual design of a web page. In your opinion, do these approaches limit creativity and originality in web page design? Support your response by suggesting contexts in which using a standard layout or template may be especially helpful or unhelpful.
Answers
Answer: The standard web component layouts and templates makes the web page seem like many others but could also make it easier for users to interact and use the web page without much trouble. The approaches do limit creativity and originality in web page design but its better to have an easy to use web page that can still look good rather than something that is confusing for the users.
Explanation:
Standard web component layouts and templates make the website look generic, but they may also make it simpler for visitors to engage with and navigate the website.
What is web component?A group of functions known as Web Components offer a common component model for the Web, enabling the encapsulation and interchange of individual HTML components.
A collection of technologies called Web Components enables you to develop reusable bespoke elements for use in web projects that have their functionality isolated from the rest of your code.
Although standard web component layouts and templates give the website a basic appearance, they may also make it easier for visitors to interact with and navigate the site.
The methods do place restrictions on uniqueness and creativity in web page design, but it is preferable to create a web page that is simple for users to navigate while still looking nice.

Suppose Alice, Bob, and Carol want to use secret key technology to authenticate each other. If they all used the same secret key K, then Bob could impersonate Carol to Alicia (actually any of three can impersonate the other to the third). Suppose instead that each had their own secret key, so Alice uses KA, Bob uses KB, and Carol uses KC. This means that each one, to prove his/her identity, responds to a challenge with a function of his/her secret key and the challenge. Is this more secure than having them all use the same secret key K? (Hint: what does Alice need to know in order to verify Carol’s answer to Alice’s challenge?)
Answers
Answer:
No. This is not more secure.
Explanation:
this is not more secure than having all of Carol, bob and Alice having the same key.
alice would be able to know Carol's key for her to be able to verify the answer Carol gave to a challenge by her. she would also have to know bob's key to do the same.
any of these 3 would have to know someone else's secret key to verify answers to any challenge.
the challenge is to know the secret keys if the other two and if done, decryption can easily be done and they can impersonate.
