Answer:
True
Explanation:
Information hiding involves using private fields within classes and it's a feature found in all object-oriented languages such as Java, Python, C#, Ruby etc.
When you use information hiding by selecting which properties and methods of a class to make public, you are assured that your data will be altered only by the properties and methods you choose and only in ways that you can control.
Consider the following code snippet.a.File inputFile = new File("dataIn.txt");b.Scanner in = new Scanner(inputFile);c.while (in.hasNext()){String input = in.next();}Which of the following statements about this code is correct?
Answer:
a) This code will read in a word at a time from the input file.
Explanation:
Below are the statements we are expected to choose the correct one from:
a) This code will read in a word at a time from the input file.
b) This code will read in the entire input file in one operation.
c) This code will read in a line at a time from the input file.
d) This code will read in a character at a time from the input file.
Further Explanation:
The statements have been coded in Java. File inputFile = new File("dataIn.txt"); is used to construct a file object with the name of the input file. The the file object is used to construct a Scanner object. Scanner in = new Scanner(inputFile);
Scanner provides methods like hasNextLine() to read data from the input file, this is what was used in the while loop process, to read the word at a time from the input file. So that the code will read in a word at a time from the input file.
Travel agents are market intermediaries who make their living by gathering, organizing, and dispensing information about travel-related services that is not readily available to most consumers. Through new information technologies, such as the Internet, much of this information can now be made directly available to consumers. Therefore, as more consumers gain access to these new technologies, demand for the services of travel agents will be drastically reduced. Which of the following, if true, most seriously weakens the argument?A. Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers.B. The amount of information available through the internet and other new information technologies is increasingfaster than the capabilities of most consumers to process itC. Many people use travel-related services, such as airlines and hotels without consulting a travel agent.D. The people who currently use the services of travel agents are also those most likely to gain access to newinformation technologiesE. The internet and other new information technologies are currently used by a relatively small proportion of thepopulation
Answer:
A. Travel agents routinely use the internet and other new information technologies as sources for the information they obtain for their customers
Explanation:
These travel agents also have access to this information on the Internet and because of it, they know the prices these airlines and hotels put up on their website and regulate their own prices, making it cheaper, so as to remain in business.
The travel agents can also gather, organise and dispense travel related information at a more affordable rate. These travel agents will access the travel and booking information from the airlines, hotels, etc and go ahead to make logistics that will make the journey easier, cheaper and more enjoyable to their customers.
The advent of travel information on the internet that is also accessed by the travel agents will not necessarily reduce the importance of the travel agents, it will merely make them offer better services because they now have a serious competitor which is ease of information on the internet.
What is the value of routeNumber after the following statement is executed if the value of zipCode is 93705? switch (zipCode) { case 93705: case 93706: routeNumber = 1; break; case 93710: case 93720: routeNumber = 2; break; default: routeNumber = 0; break; }
Answer:
The output of the given code is "1".
Explanation:
In the given switch case code, a switch is used in which a variable routeNumber is defined that accepts an integer value, inside the switch statement inner case is used, which can be described as follows:
In the first case, two case value is check that is "93705 and 93706", in which any of the value is found it will routeNumber value to 1 then break the statement. If the above case value does not match then it will go to the next case, in this case, we also check two values that are "93710 and 93720", if any of the value is found it will routeNumber value to 2 then break the statement. If both of the above condition is false it will go to default then it will routeNumber value to 0 then break the statement, but in this ZipCode value is "93705", so it will found in case 1 then it will return a value that is equal to 1."The effectiveness of memory retrieval is directly related to the similarity of cues present when the memory was encoded to the cues present when the memory is retrieved."

You have found that the network cable runs across high-traffic areas on the floor, causing the cables to wear through and break. You have replaces the cable with a plenum rated, shielded, twisted pair cable. You would like to minimize the problem and prevent it from happening again. What should you do?
Answer:
The answer is "Pass the cable into the ceiling instead of over the floor".
Explanation:
Network access explains the complex process of link different parts of the network with each other, e.g. while using switches, routers, and access points, and whether, that system works.
To replace the cable with a pair cable graded in plenum, covered, twisted. We use the cable to pass through the ceiling rather than through the concrete, eliminating the issue and stopping it from occurring again.An interface on a Windows network print client that works with a local software application, such as Microsoft Word, and a local printer driver to format a file to be sent to a local printer or a network print server.

}
}
You write a class, FrozenYogurt, which extends FrozenDesert. Which of the following is a correct implementation of the constructor for FrozenYogurt?
I. public FrozenYogurt() { System.out.println("I'm the new ice cream"); super(); }
II. public FrozenYogurt() { super(); System.out.println("I'm the new ice cream"); super(); }
III. public FrozenYogurt() { super(); System.out.println("I'm the new ice cream"); }
a. I only
b. II only
c. III only
d. I and II
e. I, II and III
Answer:
Option c is the correct answer for the above question.
Explanation:
The super is a keyword in java which is used to call the parent class constructor from the child class constructor, but the only one thing is important to write the super is the constructor that the super keyword needs to be written as a first-line where it is used.The above question has three option which holds the constructor, in which option 1 and 2 holds the super keyword as the last line. So this option is not to hold the correct constructor.But option 3 will hold the Super as the first line, Hence this is the correct use of the constructor.And Only option c states about option 3 while the other is states about the other option. Hence option c is the correct answer.The correct implementation of the constructor for FrozenYogurt is (c)
The definition of the FrozenDeser is given as:
public class FrozenDesert{
public FrozenDesert(){
System.out.println("Yum");} }
To implement the constructor of the class, we make use of the following syntax
public FrozenYogurt() { super();
//Operation
}
Using the above syntax, we can conclude that the correct implementation of the constructor for FrozenYogurt is (c)

Answer:
Higher voice
Explanation:
A soprano singer has a higher pitched voice than other female vocal ranges such as alto. The soprano voice range is the highest for females, capable of singing above middle C.
A soprano singer will have a higher pitched voice compared to an alto, who has a lower pitched female vocal range. In Western music, voice ranges are categorized into four main types: soprano and alto for females, and tenor and bass for males, with soprano being the highest female voice type and bass being the lowest male voice type.
The human voice functions as a wind instrument, with the vocal cords creating vibrations that vary in tension to produce different pitches, making the soprano voice range capable of singing almost exclusively above middle C, which results in higher pitches.

In this exercise, you will write some code that reads n unique (no duplicates!) non-negative integers, each one less than fifty (50). Your code will print them in sorted order without using any nested loops-- potentially very efficient! We'll walk you through this: First, assume you are given an int variable n, that contains the number of integers to read from standard input. Also assume you are given an array, named wasReadIn, of fifty (50) bool elements and initialize all the elements to false. Third, read in the n integers from the input, and each time you read an integer, use it as an index into the bool array, and assign that element to be true-- thus "marking" in the array which numbers have been read. Lastly the "punchline": write a loop that traverses the bool array: every time it finds an element that is true it prints out the element's INDEX -- which was one of the integers read in. Place all the numbers on a single line, separated by a single spaces. Note: this technique is not limited to 50 elements-- it works just as well for larger values. Thus, for example you could have an array of 1,000,000 elements (that's right-- one million!) and use it to sort numbers up to 1,000,000 in value!
Answer:
// This program is written in C++

Complete the second clause of the following Prolog program for member/2 where member(X, Y) checks whether X is an element (a member) of a list Y. member(X,[X|R]). member(X,[Y|R]) :- ____________.A. member(X,R).
B. member(X,Y).
C. member(_,R).
D. member(Y,R).
E. member(X,Y).
Answer:
The answer is "Option A"
Explanation:
In the given program code, two-member "X, Y" is used, in which X is an element of the list and Y is the list. In this another variable R declares, that store a number for the match, in this question choice "A" is correct because it uses an element and variable "R" for check and wrong choices can be described as follows:
In option B, in this two-parameter is used, in which one is an element and one is the list, that's why it is incorrect. In option C, It is wrong because there is no underscore variable. Option D and Option E both were wrong because in this list is passed as the parameter.Option A.To complete the second clause of a Prolog program for member/2, use 'member(X, [Y|R]) :- member(X, R).'
The question asks how to complete the second clause of a Prolog program for member/2. The member/2 predicate checks whether an element is part of a list. The correct completion of the clause is:
member(X, [Y|R]) :- member(X, R).
This means that if X is not the head of the list (Y), Prolog will recursively check if X is a member of the rest of the list (R).

A user makes a request to implement a patch management service for a company. As part of the requisition the user needs to provide justification for the request. What three reasons can the user use to justify the request?
Answer:
1. The ability to control when updates occur
2. The ability to obtain reports on systems
3. No opportunities for users to circumvent updates
Explanation:
To understand patch management, one needs to understand first what a patch is. A patch is simply a piece of code that improves a program already installed into your system. They are created to correct issues in an already-released program when a bug is discovered without the need to re-create the program altogether. Patch management is therefore the process of installing (and managing) the latest patches - code changes which improve the system or fix security vulnerabilities — on various systems within a network.
Based on the objective of the patch management as defined above, the user can streamline his justification for the request with the below three reasons:
1. The ability to control when updates occur
2. The ability to obtain reports on systems
3. No opportunities for users to circumvent updates
Final answer:
Implementing a patch management service enhances security, maintains system reliability and uptime, and reflects employee support for proactive IT maintenance.
Explanation:
A key part of any business's cybersecurity strategy is the implementation of a patch management service. The first reason for this request is that patch management ensures that software is up to date and protected from known vulnerabilities, thereby enhancing security. This is particularly critical to protect against data breaches which can have significant financial and reputational impact on a company.
Secondly, maintaining system reliability and uptime is essential for business operations. Patch management helps in pre-empting software issues that could lead to system downtime or performance problems, ensuring that business activities can continue without interruption.
Lastly, the fact that the majority of employees are in favor of adopting this solution adds a layer of internal support for the initiative, showcasing a proactive stance towards IT maintenance which can foster a culture of security-mindedness throughout the organization.
