In this exercise, you will need to create a static method called findString in the MatchingString class that should iterate over String[] arr looking for the exact match of the String that is passed as a parameter.
Return the index of the array where the String is found; if it does not exist in the array, return -1.
For example, if the word “Karel” is passed in, your method would return 1.
Answers
Answer:
Explanation:
The following code is written in Java. It is a static method that takes in a String parameter and loops through the String array called arr comparing each element in the array with the word parameter that was passed. If it finds a match the method returns the index of that word, otherwise it will return -1
public static int findString(String word){
int index = -1;
for (int x = 0; x < arr.length; x++) {
if (word == arr[x]) {
index = x;
break;
}
}
return index;
}
What is the recommended solution if a computer performs slowly?
Answers
Answer:
Not sure what the class/context is, but here's what I'd do to diagnose a problem like that:
- Check to see what programs have high utilization of system resources in task manager and end them
- Prevent background startup processes from occuring on restart or from running in the background during normal use
- Figure out what hardware component is bottlenecking the system and upgrade it (HDD to SSD would be one example)
- If the issue is malware related, I would "flatten" the PC by wiping the entire system and reinstalling the OS (though some malware can persist even across this)
Source: I've worked as labs support
If a computer is performing slowly, there are several recommended solutions one can try to improve its performance, such as closing unnecessary programs, restarting the computer, etc.
Reviewing the programs that automatically start when the computer boots up and disabling unnecessary startup programs to reduce the time it takes for the computer to start and free up system resources. The specific solution may vary depending on the computer's operating system, hardware, and specific performance issues. It's always a good idea to back up important files before making any changes to your computer's configuration. If the performance issues persist, seeking assistance from a computer technician or IT professional may be necessary.

Answers
Explanation:
A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process. In fact, calculation underlies many activities that are not normally thought of as mathematical. Walking across a room, for instance, requires many complex, albeit subconscious, calculations. Computers, too, have proved capable of solving a vast array of problems, from balancing a checkbook to even—in the form of guidance systems for robots—walking across a room.
Before the true power of computing could be realized, therefore, the naive view of calculation had to be overcome. The inventors who laboured to bring the computer into the world had to learn that the thing they were inventing was not just a number cruncher, not merely a calculator. For example, they had to learn that it was not necessary to invent a new computer for every new calculation and that a computer could be designed to solve numerous problems, even problems not yet imagined when the computer was built. They also had to learn how to tell such a general problem-solving computer what problem to solve. In other words, they had to invent programming.
They had to solve all the heady problems of developing such a device, of implementing the design, of actually building the thing. The history of the solving of these problems is the history of the computer. That history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. In addition, see the articles computer science and supercomputer.
Early history
Computer precursors
The abacus
The earliest known calculating device is probably the abacus. It dates back at least to 1100 BCE and is still in use today, particularly in Asia. Now, as then, it typically consists of a rectangular frame with thin parallel rods strung with beads. Long before any systematic positional notation was adopted for the writing of numbers, the abacus assigned different units, or weights, to each rod. This scheme allowed a wide range of numbers to be represented by just a few beads and, together with the invention of zero in India, may have inspired the invention of the Hindu-Arabic number system. In any case, abacus beads can be readily manipulated to perform the common arithmetical operations—addition, subtraction, multiplication, and division—that are useful for commercial transactions and in bookkeeping.
The abacus is a digital device; that is, it represents values discretely. A bead is either in one predefined position or another, representing unambiguously, say, one or zero.
Analog calculators: from Napier’s logarithms to the slide rule
Calculating devices took a different turn when John Napier, a Scottish mathematician, published his discovery of logarithms in 1614. As any person can attest, adding two 10-digit numbers is much simpler than multiplying them together, and the transformation of a multiplication problem into an addition problem is exactly what logarithms enable. This simplification is possible because of the following logarithmic property: the logarithm of the product of two numbers is equal to the sum of the logarithms of the numbers. By 1624, tables with 14 significant digits were available for the logarithms of numbers from 1 to 20,000, and scientists quickly adopted the new labour-saving tool for tedious astronomical calculations.
Most significant for the development of computing, the transformation of multiplication into addition greatly simplified the possibility of mechanization. Analog calculating devices based on Napier’s logarithms—representing digital values with analogous physical lengths—soon appeared. In 1620 Edmund Gunter, the English mathematician who coined the terms cosine and cotangent, built a device for performing navigational calculations: the Gunter scale, or, as navigators simply called it, the gunter. About 1632 an English clergyman and mathematician named William Oughtred built the first slide rule, drawing on Napier’s ideas. That first slide rule was circular, but Oughtred also built the first rectangular one in 1633. The analog devices of Gunter and Oughtred had various advantages and disadvantages compared with digital devices such as the abacus. What is important is that the consequences of these design decisions were being tested in the real world.
Digital calculators: from the Calculating Clock to the Arithmometer
In 1623 the German astronomer and mathematician Wilhelm Schickard built the first calculator. He described it in a letter to his friend the astronomer Johannes Kepler, and in 1624 . .
A university with remote campuses, which all use different service providers, loses Internet connectivity across all locations. After a few minutes, Internet and VoIP services are restored, only to go offline again at random intervals, typically within four minutes of services being restored. Outages continue throughout the day, impacting all inbound and outbound connections and services. Services that are limited to the local LAN or WiFi network are not impacted, but all WAN and VoIP services are affected. Later that day, the edge-router manufacturer releases a CVE outlining the ability of an attacker to exploit the SIP protocol handling on devices, leading to resource exhaustion and system reloads. Which of the following BEST describe this type of attack?

1. SUM
2. AVERAGE
3. MAx
4. MIN
5. COUNT
Answers
Answer:
1. SUM --- The SUM function is used to sum all the values that are in a given range. Thus, for example, if you want to add the values between cells A1 and A3, you must write the following command: =SUM(A1:A10)
2. AVERAGE --- The AVERAGE function allows you to average a range of values, throwing the average of these values in the cell where the function is typed. For example, if you want to average the values included between B1 and B3, you should write the following function: =AVERAGE (B1: B3).
3. MAX --- The MAX function, for its part, returns the maximum value of the values included in the function. For example, if the maximum value included between the values C1 and C3 is known, the following function must be written: =MAX (C1: C3).
4. MIN --- The MIN function, in turn, allows to identify the minimum value of the range of values included in the function. For example, if the minimum value included between the values D1 and D3 is known, the following function must be written: =MIN (D1: D3).
5. COUNT --- The COUNT function, finally, is used to count all the cells that have numbers, which have been included in the range of the function. For example, if you want to count all cells that contain numbers between the values E1 and E3, you must write the following function: =COUNT (E1: E3).

Answer:
D) 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
Explanation:
The problem here is to use the factorial method to find;
10!
The factorial of any number is given as:
a! = (a - 1) x (a - 2) .........(a - n)
It is the product of any integer from 1 to that number.
So;
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
The solution is therefore 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
When defining a class, it is a best practice to declare ____ as private. constructors mutators nothing should be private accessors variables
Answers
Answer:
The answer is "variables".
Explanation:
It is necessary to declare a variable privately when declaring a class because the private variable 'protects' the code while it is in operation. It may not aim to protect it at this stage from changing the codes themselves for other developers. Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.

System.out.println(s); //Problem 4:
}
public static void myMethod(double floozy, MyClass anObj, int a[ ], String s)

anObj.gravy = 10.001;
a[2] = 100; s = "good bye";

Answers
Answer:
Explanation:
Each of the following println statements will print the following values
ystem.out.println(floozy); // Problem 1: 97.4
System.out.println(theObj.gravy); //Problem 2: 107.43
System.out.println(xray[2]); //Problem 3: 100
System.out.println(s); //Problem 4: Hello
This is because out of all of the variables that the myMethod gives a value to, the only variable that is being saved back to the global variable in the main method is a[2]. The other variables are being saved as instance variables and not being returned. Therefore, when the println statements are called they target the local variables in the main method.

Organizations can use dictionaries to disallow passwords during the reset process and thus guard against easy-to-guess passwords.
a) true
b) false
Answers
Answer:
a) true
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
With cybersecurity theory, security standards, frameworks and best practices we can guard against cyber attacks and easy-to-guess passwords.
An example of best practices in cybersecurity is the use of alphanumeric password with certain composition and strength, such as a minimum of eight (8) characters. This would ensure there's a formidable wall to protect data and an unauthorized access or usage of the system network.
A dictionary attack typically involves accessing a list of commonly used passwords by end users rather than a random guess.
Hence, organizations can use dictionaries to disallow passwords during the reset process and thus guard against easy-to-guess passwords.
