Consider the following method, which is intended to return the index of the first negative integer in a given array of integers. public int positionOfFirstNegative(int[] values) { int index = 0; while (values[index] >= 0) { index++; } return index; } What precondition is needed on the values array so that the method will work as intended?
Answer:
The answer is "The array values must contain at least one negative integer".
Explanation:
In the above-given code, a method "positionOfFirstNegative" is declared, that accepts an array "values" as a parameter, inside the method an integer variable index is declared, that use in the while loop to check array value is greater than equal to 0, if the conditional is true it will increments the index value and return its value, that's why in this question array value include at least one negative value.

Martha has a large data list and wants to sort it quickly and efficiently. Which algorithm should Martha use
Answer:
quicksort
Explanation:
There are many types of asymptotically efficient sorting algorithms that can be used but one of the more commonly used for large data lists would be quicksort. This is a sorting algorithm that focuses on choosing a value from the list and working around that value in order to sort the data piece by piece. For larger data sets this method is widely used due to its speed and efficiency which is exactly what Martha needs in this scenario.

Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a printInfo() method that overrides the Book class' printInfo() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes.
Ex. If the input is:
The Hobbit J. R. R.
Tolkien
George Allen & Unwin
21 September 1937
The Illustrated Encyclopedia of the Universe
James W. Guthrie Watson-Guptill
2001
2nd
the output is:
Book Information:
Book Title: The Hobbit
Author: J. R. R. Tolkien
Publisher: George Allen & Unwin
Publication Date: 21 September 1937
Book Information:
Book Title: The Illustrated Encyclopedia of the Universe
Author: James W. Guthrie
Publisher: Watson-Guptill
Publication Date: 2001
Edition: 2nd
Number of Volumes: 1
The program relating to the encylopedia is illustrated below:
public class Encyclopedia extends Book {
String edition;
int numVolumes;
public String getEdition() {
return edition;
}
public void setEdition(String edition) {
this.edition = edition;
}
print getNumVolumes() {
return numVolumes;
}
public void setNumVolumes(int numVolumes) {
this.numVolumes = numVolumes;
}
public void printInfo() {
System.out.println("Book Information: ");
System.out.println(" Book Title: " + super.title);
System.out.println(" Author: " + author);
System.out.println(" Publisher: " + publisher);
System.out.println(" Publication Date: " + publicationDate);
System.out.println(" Edition: " + getEdition());
System.out.println(" Number of Volumes: " + getNumVolumes());
}
How to illustrate the information?After analyzing both of these classes I have created the following code that grabs and overrides the printInfo() method in order to add and print the edition and number of volumes as well.
In this case, the encylopedia was illustrated above.

a 50.5 force is applied to a golf ball generating an initial acceleration of 15 m/s2 caculate the mass of the golf ball.
Answer:
Mass = 3.37 Kg
Explanation:
Given the following data;
Force = 50.5N
Acceleration = 15m/s²
To find the mass of the golf ball;
Force is given by the multiplication of mass and acceleration.
Mathematically, the formula for force is;
[tex] F = ma[/tex]
Where;
F represents force measured in Newton.m represents the mass of an object measured in kilograms.a represents acceleration measured in meter per seconds square.Making mass (m) the subject of formula, we have;
[tex]Mass (m) = \frac{F}{a}[/tex]
Substituting into the equation;
[tex]Mass (m) = \frac{50.5}{15}[/tex]
Mass = 3.37 Kg
When measuring processor speed,a megahertz is much faster than a gigahertz.true or fals
Answer: False
Explanation:
The statement in the question is wrong. When measuring processor speed, a megahertz is slower than a gigahertz.
We should note that:
1 megahertz = 1 million cycles per second
1 gigahertz = 1 billion cycles per second.
Therefore, we can see that a gigahertz is faster than a megahertz.

Answer:
Explanation:
The following code is written in Python programming language and as requested takes three int/float variables. Then it sums up the three grades and places the result into a variable called sum. Then it creates a variable called average and divides the sum by three to get the actual average. Finally, it prints the value of the average variable to the user.

The definition of network is:
A. the world wide web
B. the internet
C. a special computer that is used to store files and programs
D. two or more computers linked by cable, telephone lines or other communication devices
[tex]\text{Hello there!}[/tex]
Networks were originally used as a government weapon 61 years ago to communicate information such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.
Our internet today is capable of communicating with bilions of computers. This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, the internet is just a large network of networks that are connected through very fast radiowaves. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, B would be incorrect.
The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, A would not be correct.
As described already, the network was a selection of computers used to communicate information to each other. C would not be correct as it states that there is only one computer being used.

Think of an area that interests you: sports, arts, entertainment, international relief efforts, government, careers, or the weather.
Think of a question you would like to answer. Is it better to wait until the battery is low before you recharge your smartphone? How does a streaming service like Netflix or Hulu decide which shows to offer?
Look for a website where someone already collected a large quantity of data to answer that question. While commercial big data sets may have tens of thousands of values, for this project, look for a data set with at least 100 values.
You are not going to write a program to analyze these data because you have not yet covered how to read data files. You can describe how the researcher(s) who collected the data used them to answer your question.
To answer a question through commercial big data sets related to an area of interest, such as the question "How does a streaming service decide which programs to offer" It is essential to understand the definition of big data and what such data is used for.
What is big data?It corresponds to a tool for processing a large volume of data with strategic objectives for collecting, organizing and interpreting the data obtained, to obtain insights and aid in decision making.
