Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class myClass, the constructor(s) should also have the name myClass.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
public void myClass(){...}
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations: Volume
Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations:
Volume = base area x height x 1/3
Base area = base length x base width.
(Watch out for integer division)
import java.util.Scanner;
public class CalcPyramidVolume {
/* Your solution goes here */
public static void main (String [] args) {
System.out.println("Volume for 1.0, 1.0, 1.0 is: " + pyramidVolume(1.0, 1.0, 1.0));
return;
}
}
Answer:
import java.util.Scanner;
public class CalcPyramidVolume {
/* Your solution goes here */
public static void main (String [] args) {
System.out.println("Volume for 1.0, 1.0, 1.0 is: " + pyramidVolume(1.0, 1.0, 1.0));
return;
}
//Begin method definition
public static double pyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
//First, calculate the base area of the pyramid
//store the result in a double variable
double baseArea = baseLength * baseWidth;
//Then, calculate the volume of the pyramid
//using the base area and the base width
double volume = 1 / 3.0 * baseArea * pyramidHeight;
//return the volume
return volume;
}
}
Output:Volume for 1.0, 1.0, 1.0 is: 0.3333333333333333
Explanation:The code above contains comments explaining the important lines of the code. The output of the code has also been provided above.
The parts of the code that are worth noting are:
(i) The return type of the method pyramidVolume should be a double since calculations are done using double values. i.e the method header should be written as
public static double pyramidVolume(){
}
(ii) The method requires three(3) parameters of type double: baseLength, baseWidth and pyramidHeight. These should be included in the method. Therefore, the complete header definition should be:
public static double pyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
}
(iii) The formula for calculating the volume of the pyramid should be:
volume = 1 / 3.0 * baseArea * baseWidth;
Rather than;
volume = 1 / 3 * baseArea * baseWidth;
This is because integer division yields integer result. If 1 / 3 is evaluated, the result will be 0 since the decimal part will be truncated thereby making the result of the volume = 1 / 3 * baseArea * baseWidth will be 0.
Therefore, the work around for that should be to write 1 / 3.0 or 1.0 / 3.0 or 1.0 / 3.
(iv) After the calculation, the result of volume should be returned by the method. This will enable a proper call by the main method for execution.

A program developed for a Web store represents customer account balances using a format that approximates real numbers. While testing the program, a software developer discovers that some values appear to be mathematically imprecise. Which of the following is the most likely cause of the imprecision?
A. The account balances are represented using a fixed number of bits, resulting in overflow errors.
B. The account balances are represented using a fixed number of bits, resulting in round-off errors.
C. The account balances are represented using an unlimited number of bits, resulting in overflow errors.
D. The account balances are represented using an unlimited number of bits, resulting in round-off errors.
Answer:
B.
Explanation:
The most likely reason for this would be that the account balances are represented using a fixed number of bits, resulting in round-off errors. Since all of the numbers being used are real numbers they would have a fixed 32 bits of data. When these values are multiplied or divided they can be irrational numbers that never end, and therefore are cut off in order to fit the available data. This would cause the numbers to be rounded and can lead to the answer being imprecise.
Which of the following passes an int argument into a method named print? Chose one option and explain why.
o print();
o print()+5;
o print("5");
o print(5);
Answer:
print(5)
Explanation:
Passing an int argument into the method named print ;
print() ; Here, the print method has no argument as it is empty
print()+5; Here also, the print method has no argument and adding +5 is an invalid syntax.
print("5") ; Here, print takes in an argument, however, the argument is a string due to the fact that 5 is enclosed by quotation marks.
print(5) ; Here, the integer is 5 is passed to the print method.

You are the IT administrator for a small corporate network. The employee in Office 1 occasionally needs a previous version of her report files. You need to configure her computer so that you can restore the computer to a point in time if needed. In this lab, your task is to complete the following:
Turn on system protection on the C: volume and set a maximum of 5% of disk space for system protection. Turn on system protection on the D: volume and set a maximum of 5% of disk space for system protection. Create a manual restore point. When naming the restore point, choose your own name for the restore point.
Answer:
Explanation:
Assuming you have Windows 8 or 10 as the operating system, you would need to do the following. In the search input in the taskbar search for "Create a System Restore Point". In this window, navigate to the System Protection tab. Here, you need to click on the drive you want, we can do C first, and click on the button that says "configure". Here you want to turn on System Protection and set the disk space to 5%. Now click apply and ok and repeat for drive D.
Once that is done you will need to create a manual restore point by clicking the button that says create and giving it the name of your choice.
Let L be the set of exactly those strings over the alphabet \Sigma = {a, b, c, g}, that satisfy all of the following properties: the length of the string is equal to 5n+3, for some natural number n greater or equal than 0; all of the first (leftmost) 2n symbols are elements of the set {b, c, g}; all of the last (rightmost) 3n symbols are elements of the set {a, b}; the symbols at position 2n+1, 2n+2, and 2n+3 (from the left, i.e., after the first 2n symbols but before the last 3n symbols) are elements of the set {c, g}; Write a complete formal definition of a context free grammar that generates L. If such a context free grammar does not exist, state that the context free grammar does not exist, and prove it.
Answer:
S -> LSR
S -> M
M -> YYY
Y -> c | g
L -> XX
X -> b | c | g
R -> ZZZ
Z -> a | b
Explanation:
This is a long time ago, but I think this does what you want.
Start symbol S expands to LSR and allows you to grow L and R on either side as much as you want. Ultimately S must be replaced by M. Then you have a pattern like LLLLLMRRRRR.
We can then further break down L into 2 times b, c or g, and similar for M and R.
The following are three possible logon scenarios. Explain why option (c) below is preferable in terms of system security. a. Welcome to XYZ computing Enter username: jones Invalid username Enter username: b. Welcome to XYZ computing Enter username: smith Enter password: password Invalid access Enter username: c. Enter username: smith Enter password: password Invalid access Enter username: smith Enter password: FpQr56 Welcome to XYZ computing
Answer:
because the password being used is of high quality
Explanation:
Option C is the most preferable in terms of system security because the password being used is of high quality. Meaning that it contains lower case and capital case letters as well as numbers. It is also a random mix of all three and is not a common word or name. The length of the password is normal but could be longer for better safety. These things make it very difficult and time-consuming for a software program to guess the password, and nearly impossible for an individual to guess.

write a java program to input two double type numbers and by using suitable mathematical functions print the maximum and minimum numbers out of the two numbers.
[tex]java \: me \: likhna \: ok[/tex]
Answer:
The program in Java is as follows:
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
double n1, n2;
n1 = input.nextDouble();
n2 = input.nextDouble();
double Max = Math.max(n1,n2);
double Min = Math.min(n1,n2);
System.out.println("Max: "+Max);
System.out.println("Min: "+Min); }}
Explanation:
This declares the numbers
double n1, n2;
This gets input for n1
n1 = input.nextDouble();
This gets input for n2
n2 = input.nextDouble();
This gets the max of both using the max function
double Max = Math.max(n1,n2);
This gets the min of both using the min function
double Min = Math.min(n1,n2);
This prints the max
System.out.println("Max: "+Max);
This prints the min
System.out.println("Min: "+Min);

What is not an advantage of a computer network?
Select one:
A.Remote Information Access
B.Interaction among cooperative application programs
C.Social Engineering
D.User Communication
E.Resource Sharing
Answer:
C. Social Engineering
Explanation:
Social engineering can be defined as an art of manipulating people, especially the vulnerable to divulge confidential information or performing actions that compromises their security.
Basically, it is a manipulative strategy or technique that involves the use of deceptive and malicious activities on unsuspecting victims in order to gain unauthorized access to their confidential or private information for fraud-related purposes. Some examples of social engineering attacks include quid pro quo, spear phishing, baiting, tailgating, water-holing, vishing, pretexting, phishing, etc.
Phishing is an attempt to obtain sensitive information such as usernames, passwords and credit card details or bank account details by disguising oneself as a trustworthy entity in an electronic communication usually over the internet.
Furthermore, phishing is a type of fraudulent or social engineering attack used to lure unsuspecting individuals to click on a link that looks like that of a genuine website and then taken to a fraudulent web site which asks for personal information.
In conclusion, social engineering being a form of cyber attack is not an advantage of a computer network.
When running on its 11.4 V battery, a laptop computer uses 8.3 W. The computer can run on battery power for 7.5 h before the battery is depleted. Part A What is the current delivered by the battery to the computer
Answer:
The correct answer is "0.73 A".
Explanation:
Given that:
Power,
P = 8.3 W
Voltage,
ΔV = 11.4 V
The current will be:
⇒ [tex]I = \frac{P}{\Delta V}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{8.3}{11.4}[/tex]
⇒ [tex]=0.73 \ A[/tex]
