3) Write a Java application that asks the user to enter the scores in 3 different tests (test1, test2, test3) for 5 students into a 2D array of doubles. The program should calculate the average score in the 3 tests for each student, as well as the average of all students for test1, test2 and test3.
Answer:
import java.util.Scanner;
public class TestScores {
public static void main(String[] args) {
// create a 2D array of doubles to hold the test scores
double[][] scores = new double[5][3];
// use a Scanner to get input from the user
Scanner input = new Scanner(System.in);
// loop through each student and each test to get the scores
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
System.out.print("Enter score for student " + (i+1) + " on test " + (j+1) + ": ");
scores[i][j] = input.nextDouble();
}
}
// calculate the average score for each student and print it out
for (int i = 0; i < 5; i++) {
double totalScore = 0;
for (int j = 0; j < 3; j++) {
totalScore += scores[i][j];
}
double averageScore = totalScore / 3;
System.out.println("Average score for student " + (i+1) + ": " + averageScore);
}
// calculate the average score for each test and print it out
for (int j = 0; j < 3; j++) {
double totalScore = 0;
for (int i = 0; i < 5; i++) {
totalScore += scores[i][j];
}
double averageScore = totalScore / 5;
System.out.println("Average score for test " + (j+1) + ": " + averageScore);
}
}
}
Explanation:
Here's how the program works:
It creates a 2D array of doubles with 5 rows (one for each student) and 3 columns (one for each test).
It uses a Scanner to get input from the user for each test score for each student. It prompts the user with the student number and test number for each score.
It loops through each student and calculates the average score for each student by adding up all the test scores for that student and dividing by 3 (the number of tests).
It prints out the average score for each student.
It loops through each test and calculates the average score for each test by adding up all the test scores for that test and dividing by 5 (the number of students).
It prints out the average score for each test.
Note that this program assumes that the user will input valid numbers for the test scores. If the user inputs non-numeric data or numbers outside the expected range, the program will throw an exception. To handle this, you could add input validation code to ensure that the user inputs valid data.
Discuss the importance of the topic of your choice to a fingerprint case investigation.
The topic of fingerprint analysis is of critical importance to a fingerprint case investigation due to several key reasons:
Identifying Individuals: Fingerprints are unique to each individual and can serve as a reliable and conclusive means of identification. By analyzing fingerprints found at a crime scene, forensic experts can link them to known individuals, helping to establish their presence or involvement in the crime. This can be crucial in solving cases and bringing perpetrators to justice.
What is the use of fingerprint?Others are:
Evidence Admissibility: Fingerprint evidence is widely accepted in courts of law as reliable and credible evidence. It has a long-established history of admissibility and has been used successfully in countless criminal cases. Properly collected, preserved, and analyzed fingerprint evidence can greatly strengthen the prosecution's case and contribute to the conviction of the guilty party.
Forensic Expertise: Fingerprint analysis requires specialized training, expertise, and meticulous attention to detail. Forensic fingerprint experts are trained to identify, classify, and compare fingerprints using various methods, such as visual examination, chemical processing, and digital imaging. Their skills and knowledge are crucial in determining the presence of fingerprints, recovering latent prints, and analyzing them to draw conclusions about the individuals involved in a crime.
Lastly, Exclusionary Capability: Fingerprints can also serve as an exclusionary tool in criminal investigations. By eliminating suspects or individuals who do not match the fingerprints found at a crime scene, fingerprint analysis can help narrow down the pool of potential suspects and focus investigative efforts on the most relevant individuals.

They have at least two components, "if" and "then." However, for more complicated if expressions, there are alternative choices like "else" and "else if." The if statement can be thought of as a true or false inquiry.
It is applied to develop a decision structure that enables more than one execution path for a programme. Only when a "boolean" expression is "true" does the "if" statement cause one or more statements to be executed. to predict what would occur if an if statement were untrue. Code must be written to determine whether the value of the variable text1 is larger than 15. The IF function lets you test for a condition and returns a result if True or False, allowing you to compare a value logically to what you anticipate. Thus, an IF statement can have two outcomes.

It also does not account for the case where the input array is a jagged array with different number of columns in each row.
Therefore, The for loop in the reverse method only goes through the elements up to arr.length-1 which means it does not reach the last element of the array. This means that the last element of the array will not be reversed.

Many documents use a specific format for a person's name. Write a program whose input is:
firstName middleName lastName
and whose output is:
lastName, firstInitial.middleInitial.
Ex: If the input is:
Pat Silly Doe
the output is:
Doe, P.S.
If the input has the form:
firstName lastName
the output is:
lastName, firstInitial.
Ex: If the input is:
Julia Clark
the output is:
Clark, J.
Answer:
Explanation:
import java.util.Scanner;
public class NameFormat {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a name: ");
String firstName = input.next();
String middleName = input.next();
String lastName = input.next();
if (middleName.equals("")) {
System.out.println(lastName + ", " + firstName.charAt(0) + ".");
} else {
System.out.println(lastName + ", " + firstName.charAt(0) + "." + middleName.charAt(0) + ".");
}
}
}
In this program, we use Scanner to read the input name consisting of the first name, middle name, and last name. Based on the presence or absence of the middle name, we format the output accordingly using if-else statements and string concatenation.
Make sure to save the program with the filename "NameFormat.java" and compile and run it using a Java compiler or IDE.

EDIT: I think I realized my mistake, I need to convert 10Mbs to bits per second, so I think its actually 16000 / 10^7 = 0.0016
which is 1.6 milliseconds?
The time taken to transmit a packet from the host to the transmission medium is called Transmission delay.
Transmission delay formula = Data size / bandwidth = (L / B) second
What is Transmission delay?Transmission delay, sometimes referred to as store-and-forward delay or packetization delay, is the time needed to push every bit of a packet into the cable in a network that uses packet switching. In other words, this is the delay brought on by the link's data rate. The length of the packet determines how long the transmission will take, not the distance between the two nodes. The bit length of the packet determines how long this delay is. At the link's input, the majority of packet switching networks employ store-and-forward transmission. Before delivering the first bit of the packet into the outgoing connection, a switch implementing store-and-forward transmission will receive (save) the complete packet to the buffer and check it for CRC errors or other issues.

As a computer science student, how do you assess your vulnerability to information theft in comparison to a famous celebrity?
Answer:
Explanation:
As a computer science student, you should assess your vulnerability to information theft by analyzing the types of information you have and where you store it, as well as the security measures you have in place to protect that information. This includes things like passwords, two-factor authentication, and encryption.
A famous celebrity, on the other hand, may have a higher level of vulnerability to information theft due to their high-profile status and the fact that they may have more sensitive information such as financial information, personal contacts, and private photos and videos. They may also be targeted more frequently by hackers and scammers who are looking to exploit their fame and popularity.
It is important to note that everyone's vulnerability to information theft is different and it is important to take the necessary steps to protect your personal information, regardless of whether you are a computer science student or a famous celebrity. This includes keeping your software and operating system updated, being cautious when clicking on links or opening email attachments from unknown sources, and not sharing personal information online.
