Can anyone help me figure out why my if statements are not executing properly? When the program executes with 7 as the value for num it should be executing the first line, but instead it goes to the third and displays, " a single digit."
public static String numberInfo(int num){
//TODO student
String numInfo;
if (num == 7) {
numInfo = "lucky sevens!";
}
if (num == 42) {
numInfo = "the answer to life the universe and everything.";
}
if (num < 10) {
numInfo = "a single digit.";
}
else {
numInfo = "a positive number.";
}
return numInfo;
}
Answer:
For the value of 7 of num, there are actually two if statements that are true and their contained code is executed.
So your line numInfo = "lucky sevens!"; is executed for sure, but then numInfo gets overwritten with by numInfo = "a single digit.";
To fix it, you have to decide how you want the program to behave, since technically, both numInfo's are equally correct.
- if you want to execute at most one if condition, chain them together like if (...) { ... } else if(...) { ... } etc.
- if you want to return multiple numInfo's, turn it into a collection where you add strings

6. In terms of a career, the word benefits refers to how much vacation and salary bonuses a person gets. True False
It is false that in terms of a career, the word benefits refers to how much vacation and salary bonuses a person gets.
The term "benefits" in the context of a profession comprises a wider range of offerings supplied by a company to an employee, even if vacation and pay bonuses might be included in the benefits package.
Benefits frequently involve additional remuneration and benefits in addition to vacation time and salary increases.
Health insurance, retirement plans, paid time off, flexible work schedules, tuition reimbursement, employee assistance programmes, wellness programmes, and other benefits are a few examples of these.
The benefits package is intended to draw in new hires, keep them on board, improve job satisfaction, and support workers' health and work-life balance. Therefore, vacation time and incentive pay are just a portion of the total benefits that an employer provides.

This means take in random integer numbers starting with 2 and ending with 4.
Meaning numbers : 2, 3 and 4
Next math.pow(a,2) means a× a = a2
So when we input 2 the function;
math.pow(a,2) returns an integer 4
You do same for input 3 , it returns 9.
For input 4 it returns 16.

The enormous amount of data and information that a company generates and consumes today can become an organizational and logistical nightmare. Storing data, integrating it and protecting it, so that it can be accessed in a fluid, fast and remote way, is one of the fundamental pillars for the successful management of any company, both for productive reasons and for being able to manage and give an effective response to the customers.
Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.
Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse.

James has a USB flash drive that he has used at work. The drive needs to be thrown away, but James wants to make sure that the data is no longer on the drive before he throws it away. What can James use to wipe the data clean?
a. Zero-fill utility
b. Format the drive
c. ATA Secure Erase
d. Smash the USB drive
Answer:
C. ATA Secure Erase
D. Smash the USB drive
Explanation:
Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.
Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.
ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.
Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.
Hi!
i want to ask how to create this matrix A=[-4 2 1;2 -4 1;1 2 -4] using only eye ones and zeros .Thanks in advance!!
The matrix A=[-4 2 1;2 -4 1;1 2 -4] can be created by using the following code in Matlab/Octave:
A = -4*eye(3) + 2*(eye(3,3) - eye(3)) + (eye(3,3) - 2*eye(3))
Here, eye(3) creates an identity matrix of size 3x3 with ones on the diagonal and zeros elsewhere.
eye(3,3) - eye(3) creates a matrix of size 3x3 with ones on the off-diagonal and zeros on the diagonal.
eye(3,3) - 2*eye(3) creates a matrix of size 3x3 with -1 on the off-diagonal and zeros on the diagonal.
The code above uses the properties of the identity matrix and the properties of matrix addition and scalar multiplication to create the desired matrix A.
You can also create the matrix A by using following code:
A = [-4 2 1; 2 -4 1; 1 2 -4]
It is not necessary to create the matrix A using only ones and zeroes but this is one of the way to create this matrix.
