Given an array of 10 names, complete the main method that outputs the name specified by the array index entered by the user. Use a try block to output the name and a catch block to catch any ArrayIndexOutOfBoundsException. Output the message from the exception object if an ArrayIndexOutOfBoundsException is caught. Output the first element in the array if the index is negative or the last element if the index is greater than the size of the array.
Hint: Format the exception outputs using the getMessage() method from the exception object. Do not hard code the exception messages.
Ex: If the input of the program is:
5
the program outputs:
Name: Jane
Ex: If the input of the program is:
12
the program outputs:
Exception! Index 12 out of bounds for length 10
The closest name is: Johnny
Ex: If the input of the program is:
-2
the program outputs:
Exception! Index -2 out of bounds for length 10
The closest name is: Ryley
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
String[] names = { "Ryley", "Edan", "Reagan", "Henry", "Caius", "Jane", "Guto", "Sonya", "Tyrese", "Johnny" };
int index;
index = scnr.nextInt();
try {
}
}
}
Answers
The program illustrates the use of catching exceptions using try and catch.
Exceptions are simply errors that can crash a programTry and catch are used to prevent errors from crashing a programThe required try and catch block is as follows:
try {
System.out.print(names[index]);
}
catch (ArrayIndexOutOfBoundsException e) {
System.out.println(e.getMessage());
}
The flow of the above code segment is as follows:
First, we begin with the try block
try {
Then the program prints the element at the index
System.out.print(names[index]); }
If the index does not exist in the array (e.g. -1 or 11), then the catch block is executed
catch (ArrayIndexOutOfBoundsException e) {
This prints the appropriate exception
System.out.println(e.getMessage()); }

Computational problem solving: Developing strategies: Given a string, S, of n digits in the range from 0 to 9, describe an efficient strategy for converting S into the integer it represents.
Answers
Given a string S of n digits in the range from 0 to 9, an efficient strategy for converting S into the integer it represents is computational problem-solving.
This process requires the following steps:
Step 1: Start by defining a variable, let's call it num, to 0, which will hold the integer representation of the string.
Step 2: Iterate through each digit in the string from left to right.
Step 3: For each digit, multiply the current value of num by 10 and then add the integer value of the digit to it.
Step 4: After iterating through all digits, the final value of num will be the integer representation of the string. For example, suppose we have the string "12345".
Using the above strategy, we would do the following:
Step 1: Define num as 0.
Step 2: Iterate through each digit in the string from left to right. For the first digit, 1, we would multiply num by 10 and then add 1, giving us num = 1. For the second digit, 2, we would multiply num by 10 again and then add 2, giving us num = 12. And so on, until we have iterated through all digits.
Step 3: After iterating through all digits, the final value of num will be the integer representation of the string, in this case, 12345.

Overview Deep in the jungles of Africa, a rare bat virus was transmitted to a group of people causing them to live forever without needing food or water. The minor side effect of this virus is that the infected people live with a continual desire to bite humans and drink their blood. Those bitten then join the world’s new biting force (also known as vampires). This program is to simulate a vampire takeover and report on the findings. Specifications We will be simulating the infection of humans by vampires on a 2D map of a size of your choosing. The simulation will show a scatter plot containing humans, vampires, food, water and garlic. On each timestep, the vampires and humans will move and interact with each other as well as with the food, water and garlic. Timesteps (5%) The heart of your program will be a loop that controls how many timesteps the program runs for. This loop will control all the other functionality (such as movement). Your program should accept 3 command line parameters but default to reasonable options in the case of their absence. The command line parameters are as follows: Initial number of humans Initial number of vampires Number of timesteps in the simulation Objects (10%) Both humans and vampires should be represented in the code as objects. Humans should have health and age variables and vampires only a health variable. They should also have methods for their various actions, such as moving, attacking, biting etc. The methods you have are up to you. 3 Humans start with a health of 100 at the beginning of the simulation and lose 1 health point for every step they move (see the movement section). Humans also start with a random age between 10 and 50 and at every timestep they age by 1. Humans don’t live past 70 timesteps. Vampires start with the health that they had as a human before becoming infected. They don’t have an age and only lose health by being bitten by other vampires (see the interaction section). Food, water and garlic could also be represented using objects but don’t have to be. The initial locations of food, water and garlic are up to you.
Answers
This program is designed to simulate a vampire takeover in the jungles of Africa. It takes place on a 2D map and displays a scatter plot showing humans, vampires, food, water, and garlic. The simulation runs for a specified number of timesteps, and during each timestep, vampires and humans move and interact with each other as well as with the objects on the map.
The core of the program is a loop that controls the duration of the simulation. It accepts three command line parameters: initial number of humans, initial number of vampires, and the number of timesteps. If no values are provided, reasonable defaults are used.
The program represents humans and vampires as objects. Humans have health and age variables, while vampires only have a health variable. They have various methods for actions like moving, attacking, and biting.
Humans start with a health of 100 and lose 1 health point for every step they take. They also have a random age between 10 and 50, increasing by 1 at each timestep. Humans cannot survive beyond 70 timesteps. Vampires begin with the same health they had as humans before turning, and they don't age. Their health decreases only if they are bitten by other vampires.
Food, water, and garlic can be represented as objects on the map, but it's not mandatory. The initial locations of these objects can be determined as desired.
In conclusion, this program simulates the spread of vampires on a 2D map in the African jungles. Humans are the primary targets of the vampires, who attempt to bite them and turn them into vampires. Vampire health decreases if they are bitten by other vampires. The presence of food, water, and garlic adds further interactions. The simulation runs for a specified number of timesteps, allowing humans, vampires, and objects to interact with each other.

Which transmission medium transmits data the fastest?
A) Twisted-pair cable
B) Coaxial cable
C) Wireless
D) Fiber-optic cable
Answers
Fiber optics: These connections are wired. It offers the quickest method of data transmission.
Why would a fibre optic cable be used?A fiber-optic cable, sometimes referred to as an optical-fiber cable, is an arrangement that resembles an electrical cable but has one or more optical fibres that are used to convey light instead of electricity. A fiber-optic cable is made up of several to hundreds of optical fibres enclosed in a plastic sheath. These are also known as optical cables or optical fibre cables, because they transmit data messages in the form of light, which travels hundreds of miles far more quickly than the electrical signals used in conventional cables. Fiber optic cables offer faster data transmission than wireless networks when the speed of the two networks is taken into account. Fiber optic cables maintain their strength even during busy times, whereas wireless networks can become slower.To learn more about Fiber-optic cable, refer to:
https://brainly.com/question/29990631
The transmission medium that transmits data the fastest is Fiber-optic cable.
Fiber-optic cables transmit data through light pulses, allowing for faster speeds and greater bandwidth compared to other transmission mediums such as twisted-pair cable, coaxial cable, and wireless.
A twisted-pair cable consists of two or more wires twisted together to reduce interference from other devices. It is often used to transmit data over short distances, such as within a building or across a campus.
However, twisted-pair cable does not transmit data as quickly as other transmission media. A coaxial cable consists of a center conductor and an outer conductor, with a layer of insulation between them. Coaxial cable is commonly used to transmit data over long distances, such as between buildings or across a city.
However, it is not as fast as fiber-optic cable. Wireless transmission refers to the use of radio waves or other electromagnetic signals to transmit data without the need for wires or cables. Wireless transmission is commonly used for mobile communication devices, such as cell phones and tablets.
However, it is not as fast as fiber-optic cable. Fiber-optic cable is a transmission medium that uses glass or plastic fibers to transmit data at high speeds over long distances. Fiber-optic cable is the fastest transmission medium, and it is often used to transmit data across continents or even across the ocean.

What is contained in the trailer of a data-link frame?
Answers
Answer:
Trailer: It contains the error detection and error correction bits. It is also called a Frame Check Sequence (FCS).
Explanation:
In the context of data-link frames, the trailer is the final part of the frame structure. It typically contains two important components:
Frame Check Sequence (FCS): The FCS is a field in the trailer that is used for error detection. It is a checksum or a cyclic redundancy check (CRC) value calculated based on the contents of the entire frame, including the header, data, and sometimes the trailer itself.
End Delimiter: The end delimiter is a specific bit pattern or sequence of bits that marks the end of the frame. It helps the receiving device recognize the end of the frame and differentiate it from subsequent frames.
Thus, the trailer, along with the header and data, forms a complete data-link frame. It is used for reliable transmission of data across a network by incorporating error detection mechanisms and frame boundaries.

A co-worker has suggested speeding up access during failed searching by keeping track of recent unsuccessful searches in a cache, or store. She suggests implementing the cache as an unsorted linked-list.
Select the best analysis for this scenario from the list below:
A. In some circumstances this may help, especially if the missing key is frequently search for.
B. An external cache will always speed up the search for previously failed searches, but only if an array-based implementation is used.
C. This is a good idea as the the linked-list implementation of the cache provides a mechanism to access the first item in O(1) steps.
D. This is always a bad idea.
Answers
The option A is the correct answer.Option A is the best analysis for this scenario from the list below. Here's why:Explanation:The binary search algorithm is used to find a particular key in a sorted array. In the case of a failed search, it takes log2 n comparisons to determine that the key is not present in the array.
If the application frequently searches for the missing key, the time required to access the array can be reduced by storing recent unsuccessful searches in a cache or store.In certain scenarios, such as when the absent key is often looked for, this might help.
An unsorted linked-list can be used to implement the cache. In such a case, the linked-list implementation of the cache provides a way to access the first item in O(1) steps. It is preferable to keep an external cache. However, it will only speed up previously unsuccessful searches if an array-based implementation is employed.

1. How many lines would be required to display a circle of diameter 200 mm within a display tolerance of 0.1 mm? What would the actual display tolerance be for this number of lines?
Answers
The number of lines required to display a circle of diameter 200 mm within a display tolerance of 0.1 mm, we can calculate the circumference of the circle and divide it by the desired display tolerance.
Circumference of the circle = π * diameter
= π * 200 mm
Number of lines required = Circumference of the circle / Display tolerance
= (π * 200 mm) / 0.1 mm
To find the actual display tolerance for this number of lines, we divide the circumference of the circle by the number of lines:
Actual display tolerance = Circumference of the circle / Number of lines
= (π * 200 mm) / (Circumference of the circle / Display tolerance)
= Display tolerance
Therefore, the actual display tolerance for the calculated number of lines will be equal to the desired display tolerance of 0.1 mm. In summary, the number of lines required to display a circle of diameter 200 mm within a display tolerance of 0.1 mm is determined by dividing the circumference of the circle by the display tolerance. The actual display tolerance for this number of lines remains at 0.1 mm.
