In Java write a method called wordCount that accepts a String as its parameter and returns the number of words in the String. A word is a sequence of one or more nonspace characters (any character other than ' '). For example, the call wordCount("hello") should return 1, the call wordCount("how are you?") should return 3, the call wordCount(" this string has wide spaces ") should return 5, and the call wordCount(" ") should return 0.
Answer:
// here is code in java.
import java.util.*;
// class definition
class Main
{
// method that return the number of words in the string
public static int wordCount(String st)
{
/* split the string by space " " delimiter
and save them into string array*/
String[] no_words=st.split(" ");
// find the length of array
int len= no_words.length;
//return the length
return len;
}
// driver function
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read input string
Scanner s=new Scanner(System.in);
// string variable
String str;
//ask user to enter string
System.out.print("please enter the string: ");
// read the string from user
str=s.nextLine();
// call the function with string parameter
int tot_words= wordCount(str);
// print the number of word in string
System.out.println("total words in the string is : "+tot_words);
}catch(Exception ex){
return;}
}
}
Explanation:
Read a string from user with the help of scanner class object.Call the function
wordCount() with string parameter.Here split the string by space " " delimiter.
Save the words into a string array.Find the length of the array and return it.
Then in the main print the number of words in the input string.
Output:
please enter the string: this string has wide spaces
total words in the string is : 5
Why is it difficult to tell whether a program is correct? How do you go about finding bugs in your code? What kinds of bugs are revealed by testing? What kinds of bugs are not?
Final answer:
Program correctness is difficult to ascertain due to the many variables and inputs that can affect a software's behavior. Bugs can be identified through methods like unit testing, and adhering to good programming practices can help prevent many common errors. Nevertheless, not all issues can be revealed by testing, especially those outside the test conditions or involving non-functional aspects of the code.
Explanation:
It is difficult to tell whether a program is correct for several reasons. First, a program might work fine for some inputs but fail for others, especially if those inputs were not considered during development. Furthermore, the complexity of modern software and the interactions between different pieces of code can introduce subtle bugs that only emerge under specific conditions. In order to find bugs, a developer engages in testing and debugging processes.
Finding Bugs in Code:
Unit testing is one effective way to find and fix bugs. This involves breaking down your program into small, testable parts and ensuring each part works correctly in isolation. By using small test files and scenarios that you can verify manually, you can more easily identify discrepancies between the expected and actual outcomes. Additionally, rapid cycling between coding and testing can help identify errors early on before they compound and become harder to isolate.
Types of Bugs Revealed by Testing:
Testing can reveal syntax errors, runtime errors, logical errors, and integration issues. However, some bugs might not be uncovered by testing, such as those that occur under rare or untested conditions, or bugs related to non-functional requirements like performance under load or security vulnerabilities.
Good Programming Practices to Avoid Bugs:
To avoid bugs, it is crucial to follow good programming practices such as writing clean, readable code, reviewing code with colleagues, and avoiding writing large chunks of code without testing. Developers should write a small amount of code, test it, and repeat this process instead of trying to develop the entire program at once.
An employee wants to access the network of the organization remotely, in the safest possible way. What network feature would allow an employee to gain secure remote access to a company network?
ACL
IPS
VPN
BYOD
Answer:
VPN
Explanation:
VPN or Virtual Private Network enables an employee to access the network of the organization remotely, in the safest possible way. The user is required to provide an authentication which enables creation of a secure link between employee computer and organization network. The data moving on the channel is encrypted to prevent eavesdropping or other security issues.
An organization is deploying a new system to the production environment. A security analyst discovers the system is not properly hardened or patched. Which of the following BEST describes the scenario?
A. A secure baseline was not established early in the process.
B. User acceptance testing was not completed.
C. Integrity checks were not conducted to ensure it was the correct system.
D. An application code error was introduced during the development phase.
Answer:
The best answer is A) A secure baseline was not established early in the process.
Explanation:
If the organization is deploying to the production environment and the security analyst discovers this risk at this point, then a secure baseline was not established, because it is impossible to successfully pass the coding and peer review instances by programmers and testing instances by the QA team without any warning to correct this problem.

A technician recently fixed a computer with several viruses and spyware programs on it and notices the Internet settings were set to redirect all traffic through an unknown proxy. This type of attack is known as which of the following?A . PhishingB . Social engineeringC . Man-in-the-middleD . Shoulder surfing
Answer:
C . Man-in-the-middle
Explanation:
The man-in-the-middle technique is about the interference of a third party in the communication channel, without any of the extremes being able to notice its existence, in this way, for the user as well as for the destination page the communication will seem normal.
In this case, by redirecting traffic to a PROXY server, the attacker will have the possibility to read all the information that passes through it, being able to obtain all the desired data.
Other Malware can be used to configure the connection of the computer through the PROXY of the attacker and in this way the channel is open, until the PROXY is disabled and the malware that redirects is blocked or uninstalled.

So in this regard IIya would be recommended OAuth technology for her federal system technology.
You also learn in class that one kilobyte of computer memory will hold about 2/3 of a page of typical text (without formatting). A typical book has about 400 pages. How many such books can a 9-gig flash drive hold? _______________
Answer:
The flashdrive can hold 35389 400-pages-books
Explanation:
If [tex]\frac{2}{3}[/tex] of a page occupies 1 kB of memory, we can calculate how much memory a book will take
[tex]2/3kB=1 page\\ x kB=400 pages\\266.67 kB=400 pages[/tex]
Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.
To do the calculation, we have to know how many kilobytes are in 9 gigabytes.
There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:
[tex]Memory_{in _kilobytes}^{} =1024\frac{kilobytes}{megabytes} *1024\frac{megabytes}{gigabytes}*9=9437184 kilobytes[/tex]
Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.
[tex]Books=\frac{Flash drive memory}{Filesize of a book} =\frac{9437184kilobytes}{266.67\frac{kilobytes}{book} } =35389,4 books[/tex]
The flashdrive can hold 35389 400-pages-books, or 14155776 pages of typical text.

How many inputs are included in the following requirement? REQUIREMENT: Write a program that asks the employee for their age. The program must subtract the age from 65, and display the age, followed by the number of years left to retirement.
Answer:
The correct answer for the given question is 1
Explanation:
Following are the program in c language
#include<stdio.h> // header file
#include<conio.h> //header file
void main() // main method
{
int age,retiredAge; // variable
clrscr(); // clear screen
printf("Enter Age : ");
scanf("%d",&age); // input age
printf("************************");
retiredAge = (65-age); // calculating retired age
printf("\nYour Age is %d",age);
if(retiredAge<0) // checking condition
{
printf("\nYou are already cross the retired age. Or Enter Invalid Age.");
}
else
{
printf("\nNo of Years Left to retired is %d",retiredAge); // dsiplay age
}
getch();
}
Output:
Enter Age : 50
************************
Your Age is 50
No of Years Left to retired is 15
Here Age is the only required input to calculate the retirement age of employee. if entered age is greater than 65 then a message is printed " You are already cross the retired age. Or Enter Invalid Age. " if entered age is valid then retiredAge is calculated with the formula retiredAge = (65-age). and finally display the age,followed by the number of years left to retirement.
Therefore 1 input are required for the above program.

Microsoft Xbox operating system provides Xbox programmers with a set of common standards to use to access controllers, the Kinect motion sensor, play sounds, draw graphics, save files, and more. Without this, games would:
a) be more reliable.
b) be a lot easier to write.
c) cost more.
d) look same.
e) not be restricted to just Microsoft's platforms.
The correct answer is: e) not be restricted to just Microsoft's platforms.
The Microsoft X box operating system provides a set of common standards that are specific to Microsoft's platforms, which can limit the portability of games to other platforms.
Here's why the other options are incorrect:
be more reliable: While consistent standards can potentially contribute to reliability, the main benefit of standards is simplifying development, not directly impacting reliability.
cost more: Standardized tools and libraries often reduce development costs by making the process more efficient.
look same: Games built on the same framework might share some similarities, but creative developers can still create diverse visual experiences even within a standardized platform.
not be restricted to just Microsoft's platforms: Standards themselves are platform-agnostic, but Microsoft's specific implementation of those standards would be limited to their platform.
Therefore, the most significant benefit of a common set of standards for X box programmers is that it significantly reduces the complexity and effort involved in writing games for the platform. This makes game development more accessible and allows developers to focus on creative aspects rather than reinventing basic functionalities.
Divided into L1, L2, and L3, the _____________ consists of a small amount of ______________ that serves as a holding area. This provides data to the CPU faster than getting it from regular memory or when RAM is unavailable because of refreshes.
Answer:
Divided into L1, L2, and L3, the cache consists of a small amount of memory that serves as a holding area. This provides data to the CPU faster than getting it from regular memory or when RAM is unavailable because of refreshes.
Explanation:
The cache is the smallest memory (in relation with other types of memory), but the fastest one, due to the proximity of the Central Processing Unit. Indeed its inside the same chip.
There are several levels of cache memory according to the proximity of the CPU, been L1 the closest one and L3 the one that is more "far". The cache memory acts an interchange memory for the register data inside the cpu, and allows to have information ready in short amount of time, avoiding the slow process of reading the disk everytime.
For the following code, how many times would the for loop execute? String str = ("Ben and Jerry's ice cream is great."); String[] tokens = str.split(" "); for (String s : tokens) System.out.println(s);
A. 1
B. 3
C. 5
D. 7
Answer:
D. 7
Explanation:
Given code:
String str = ("Ben and Jerry's ice cream is great.");
String[] tokens = str.split(" ");
for (String s : tokens) System.out.println(s);
Splitting the given sentence on space character yields 7 tokens, namely:
Ben , and , Jerry's , ice , cream , is , great.
So the for loop will execute 7 times, once for each token because the loop variable s is assigned an individual token on each iteration.

Select the term used to describe the process, within the context of Active Directory, that allows a person with higher security privileges to assign authority to a person of lesser security privileges to perform certain tasks.
a) Authority delegation
b) Policy control
c) OU control
d) Delegation of control
Within Active Directory, the process for granting a user with lower privileges the authority to perform certain tasks by someone with higher privileges is known as Delegation of control.
Explanation:The term used to describe the process in Active Directory that allows a person with higher security privileges to assign authority to a person of lesser security privileges to perform certain tasks is d) Delegation of control.
In Active Directory, delegation of control is instrumental for distributing the management of resources, giving limited administrative rights to users without elevating their overall privileges within the network. This helps maintain a secure and structured management environment by ensuring that administrative tasks can be carried out effectively while following the principle of least privilege.
Your boss has purchased a new laptop for business use and has asked you to make sure the data he plans to store on the laptop is secure. Which of the following security measures is the most important to implement to keep the data secure? Second in importance?
a. Use BitLocker Encryption with the TPM chip.
b. Enable Secure boot.
c.Set a supervisor password to BIOS/UEFI.
d.Disable booting from the optical drive.
Answer:
a. Use BitLocker Encryption with the TPM chip.
b. Enable Secure boot.
Explanation:
Bit Locker encryption is a feature included in Microsoft windows that to in pro and enterprise version only.it is full volume encryption.First it was introduced in windows Vista.It is crafted to protect the data by providing encryption.
Secure boot makes sure that the device boots using Operating system or software trusted by the manufacturer.
Final answer:
The most important security measure is to use BitLocker Encryption with the TPM chip, followed by enabling Secure Boot to ensure system integrity during bootup. These provide robust data protection and prevent unauthorized access or booting from potentially malicious software.
Explanation:
To ensure the data on the new laptop for business use is secure, the most important security measure to implement is to use BitLocker Encryption with the TPM chip. BitLocker is a full disk encryption feature included with Windows designed to protect data by providing encryption for entire volumes. By using it with the Trusted Platform Module (TPM) chip, it adds additional security by storing cryptographic keys in a tamper-resistant way.
The second most important security measure would be to enable Secure Boot. Secure Boot is a feature in the UEFI firmware that ensures that the system boots only with software that is trusted by the Original Equipment Manufacturer (OEM). This prevents malware from booting at startup, which is a critical security measure.
Setting a supervisor password to BIOS/UEFI and disabling booting from optical drive are additional security measures, but they are less important compared to the encryption of the hard drive and ensuring that the system boots securely.

Given an int variable k, an int array incompletes that has been declared and initialized, an int variable nIncompletes that contains the number of elements in the array, an int variable studentID that has been initialized, and an int variable numberOfIncompletes, Write code that counts the number of times the value of studentID appears in incompletes and assigns this value to numberOfIncompletes. You may use only k, incompletes, nIncompletes, studentID, and numberOfIncompletes.
Answer:
I will code in Javascript.
Preconditions:
The variables k, incompletes has been declared and initialized.
The variable nIncompletes contains the number of elements of incompletes.
The variable stududentID has been declared and initialized.
The variable numberOfIncompletes has been declared.
Script:
numberOfIncompletes = 0; //initialize numberOfIncompletes
for( k = 0; k < nIncompletes; k++) {
if(incompletes[k] == studentID){ //if the element of array is equal to studentID
numberOfIncompletes++; //adds 1 to numberOfIncompletes
}
}
Explanation:
The script uses a for loop to go through the entire array incompletes, comparing the k variable with nIncompletes and adding 1 on each pass.
Then inside the for, uses an if statement to compare if the actual element is equal to studentID, if equal adds 1 numberOfIncompletes.
