Answer:
Here is some code that works for me:
import java.util.Scanner;
public class badsubscriptcaught {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String[] names = {"Jake", "Jack", "Jacob", "Ben", "Liam", "Noah", "Oliver", "William", "Elijah", "James"};
int number = Integer.parseInt(scanner.nextLine());
try{
System.out.println(names[number]);
}catch (ArrayIndexOutOfBoundsException exception){
System.out.println(exception + " isn't a vailid value.");
}
}
}
Exceptions are used to prevent a program from crashing, by managing the error or bugs.
The program in Java where comments are used to explain each line is as follows:
import java.util.Scanner;
public class badsubscriptcaught{
public static void main(String[] args) {
//This creates a scanner object
Scanner input = new Scanner(System.in);
//This gets input for the index to print
int arrayIndex = input.nextInt();
//This initializes the array.
//Note that, the names can be replaced
String[] nameArray = {"Liam", "Olivia" , "Noah", "Emma", "Oliver","Ava","Elijah","Charlotte","Michael","David"};
//This creates a try-catch exception
try{
//This prints the array element at the corresponding index, if the index is between 0 and 9
System.out.println(nameArray[arrayIndex]);
}
//This catches the exception
catch (ArrayIndexOutOfBoundsException exception){
//This prints the exception
System.out.println(exception);
}
}
}
At the end of the program, the exception is printed, if any.

It's common to print a rotating, increasing list of single-digit numbers at the start of a program's output as a visual guide to number the columns of the output to follow. With this in mind, write nested for loops to produce the following output, with each line 60 characters wide: | | | | | | 123456789012345678901234567890123456789012345678901234567890

Explanation:
See attachment for program output format
The next two instructions create a nested for loop
for i in range(0,6):
for i in range(0,9):
This prints 9 spaces
print(" ",end='')
This prints a vertical line at the top of the end of the spaces printed
print("|",end='')
This prints a new line

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send an packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure. a = IP() a.dst = ’1.2.3.4’ a.ttl = 3 b = ICMP() send(a/b) If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result.

The following code will not display the results expected by the programmer. Can you find the error? Declare Real lowest, highest, average Display "Enter the lowest score." Input lowest Display "Enter the highest score." Input highest Set average = low + high / 2 Display "The average is ", average, "."
Based on the information given, the first error in the code is that the Variable name is lowest, NOT low, and Set average = low + high / 2.
How to find the error in the code.For Error 2: Variable name is highest, NOT high and Set average = low + high / 2
For Error 3 : Set average = low + high / 2. Thus, you will need to add the lowest and highest, then perform the division by 2
Set average = (lowest + highest) / 2 is the the correct statement.

Exercise 3.7.1: Proving statements about odd and even integers with direct proofs. info About Each statement below involves odd and even integers. An odd integer is an integer that can be expressed as 2k 1, where k is an integer. An even integer is an integer that can be expressed as 2k, where k is an integer.
The question is incomplete. The complete question is :
Each statement below involves odd and even integers. An odd integer is an integer that can be expressed as 2k+1, where k is an integer. An even integer is an integer that can be expressed as 2k, where k is an integer. Prove each of the following statements using a direct proof. (a) The sum of an odd and an even integer is odd. (b) The product of two odd integers is an odd integer.
Solution :
Odd number integers = 2k + 1, where k is integer
Even number integer = 2k
a). Odd integer + even integer
= 2k + 1 + 2k
= 4k + 1
= 2(2k) + 1
Let 2k = t, where t is integer
= 2t + 1
= Odd integer by definition
If number is 2t + 1 where t belongs to integer, then it is odd integer.
Hence proved.
b). Product of two odd integers : [tex]$2k_1 + 1,\ \ 2k_2 +1 $[/tex] where [tex]$k_1, k_2 $[/tex] belongs to integer.
[tex]$(2k_1+1)(2k_2+1)= 4k_1k_2+2k_1+2k_2+1$[/tex]
[tex]$2(2k_1k_2)+2(k_1+k_2)+1$[/tex]
Let [tex]$2k_1k_2 = a$[/tex] and [tex]$k_1+k_2 = b $[/tex]
here, a and b belongs to integers since [tex]$k_1$[/tex] and [tex]$k_2$[/tex] are integers.
We get:
2a+2b+1
= 2(a+b)+1
= 2l + 1, Let (a+b)=l and l belongs to integers.
It is odd integer by definition.
Hence proved.

Answer:
If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.
One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.
In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.
Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.
IP address network
For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.
Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.
To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.
To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.
For example, 01110100 in binary is 116 in decimal:
A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:
Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.
Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.
Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.
Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.
With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.
Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported
Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1
End address: 192.168.58.16 – 2 = 192.168.58.14
Broadcast address: 192.168.58.16 – 1 = 192.168.58.15

In the given scenario, if we use "InputStream" class object that inputs value from the user-end, in which we use "readInt" keyword. In Java, this function of the DataInputStream class reads 4 input bytes and returns an integer value. This method takes the next 4 bits from the input stream, transforms them to integers, and would then returns.
And the wrong choice can be defined as follows:
For choice 1, it use the "readLine" method which inputs the string value.For choice 2, it use the "println" method which prints value.For choice 4, the "nextInt" method is the part of "Scanner" class.Therefore, the answer is "Option 3", which is "var applesToBuy - readInt("How many apples would you like?");".
