Design a RomanNumerals class that takes a number within 1 to 10 and display the Roman numeral version of that number (I, II, III, IV, V … X). If the number entered by the user is outside the range of 1-10, the program should display an error message. Code a driver class RomanNumeralsApp to test the class by asking user to enter a number, creating an object of RomanNumerals and calling its methods getNumber, setNumber, convertNum, and displayResult to perform the described task.
Answer:
Explanation:
The following code is written in Java. It creates a RomanNumberals class with all of the requested methods, including a convertNum method and displayResults method. The user is then asked to input a number within the main method. A RomanNumeral object is created, passed the userInput and all of it's methods are called for testing. A test output can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter a number: ");
int number = in.nextInt();
RomanNumerals romanNumeral1 = new RomanNumerals();
romanNumeral1.setNumber(number);
System.out.println("Test getNumber Method: " + romanNumeral1.getNumber());
romanNumeral1.convertNumber();
romanNumeral1.displayResult();
}
}
class RomanNumerals {
int number;
String romanNumeral;
public RomanNumerals() {
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public void convertNumber() {
switch (this.number) {
case 1: romanNumeral = "I"; break;
case 2: romanNumeral = "II"; break;
case 3: romanNumeral = "III"; break;
case 4: romanNumeral = "IV"; break;
case 5: romanNumeral = "V"; break;
case 6: romanNumeral = "VI"; break;
case 7: romanNumeral = "VII"; break;
case 8: romanNumeral = "VIII"; break;
case 9: romanNumeral = "IX"; break;
case 10: romanNumeral = "X"; break;
default: System.out.println("Not a valid number"); break;
}
}
public void displayResult() {
System.out.println("Number " + this.number + " is represented as " + this.romanNumeral);
}
}

Unchecked exceptions require you surround the code that might throw such an exception with a try block or you must use a throws statement at the end of the method signature. Failure to do one of these two things will result in a compile error.
a. True
b. False
Answer:
b. False
Explanation:
False, unchecked exceptions do not cause compilation errors and do not require try/catch blocks or throws statements. However, although they are not required it is good programming to include them in order to handle any exceptions that may arise. If you do not include a proper way to handle such an exception the program will still run but may run into an exception during runtime. If this occurs then the entire program will crash because it does not know how to handle the exception since you did not provide instructions for such a scenario.

Abstract art may be - and may seem like - almost anything. This because, unlike the painter or artist who can consider how best they can convey their mind using colour or sculptural materials and techniques. The conceptual artist uses whatever materials and whatever form is most suited to putting their mind across - that would be anything from the presentation to a written statement. Although there is no one kind or structure employed by abstract artists, from the late 1960s specific tendencies emerged.
Which orientation style has more height than width?
Answer:
"Portrait orientation" would be the correct answer.
Explanation:
The vertical picture, communication as well as gadget architecture would be considered as Portrait orientation. A webpage featuring portrait orientation seems to be usually larger than large containing lettering, memo abases as well as numerous types of content publications.One such volume fraction also becomes perfect for impressionism depicting an individual from either the top.Thus the above is the correct answer.
write the sql code to generate the total hours worked and the total charges made by all employees . the results are shown in fig.P7.8
Answer:
Select SUM(HOURS), SUM(CHARGES) from employees
Explanation:
The table structure is not given. So, I will assume that the table name is "employees", the columns to retrieve are "hours" and "charges"
Having said that, the function to retrieve the total of column is the sum() function.
So, the query is as follows:
Select ----> This means that the query is to retrieve from the table
SUM(HOURS), SUM(CHARGES) --- This represent the records to retrieve
from employees ---- This represents the table to retrieve from.
what's the difference between pseudo code and natural language
Answer:
The pseudo-code describes steps in an algorithm or another system in plain language. Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming.
Natural languages consist of phrases, usually declarative phrases, with a sequence of information.
Explanation:
Pseudo-Code is often designed for human reading rather than machine reading with structural conventions of a normal language of programming. It usually omits information that is essential to the understanding of the algorithm by the machine, for example, variable declarations and language code.Easily human, but not machines, use the natural languages (like English).Natural languages also are creative. Poetry, metaphor, and other interpretations are permitted. Programming permits certain style differences, but the significance is not flexible.The aim of using pseudo-code is to make it easier for people to comprehensibly than standard programming language code and to describe the key principles of an algorithm efficiently and environmentally independently. It is usually used for documenting software and other algorithms in textbooks and scientific publications.What intangible benefits might an organization obtain from the development of an
information system?
Answer:
The immaterial benefits stem from the development of an information system and cannot easily be measured in dollars or with confidence. Potential intangible advantages include a competitive need, timely information, improved planning and increased flexibility in organisation.
Explanation:
Intangible advantages
Take faster decisionsCompetitive needMore information timelyNew, better or more information availability.Lower productivity and the lack of 'think outside' employees and managers as well as greater sales include the intangible costs of such an operational environment. All these factors improve when employees spend less of their time in addressing current methods of operation and are concerned about whether they will have a job or an employer in six months or a year. The automation level envisaged in this new system should enhance the overall efficiency of management. The operative controls and design functions should be simplified by tight system integrations with accessible automated database sources. However, it is difficult to describe the exact form of these simplifications.
Tangible costs of the new system include costs of analysis, design and construction of the system, such as the recruitment of contractors or new employees, and the assignment of existing staff. Also consideration shall be given to hardware, software purchased and operating costs. Intangible costs include disturbances to the current activities caused by development and deployment and potential adverse effects on the morals of employees.
While the new system may feel good in the long term, short-term stress and other negative consequences will still be present. In the way that Reliable does virtually everything, the system is the focus of a major change. An organisation's monumental change has widespread negative effects on operations and employees.
Compute the approximate acceleration of gravity for an object above the earth's surface, assigning accel_gravity with the result.
The expression for the acceleration of gravity is: (G*M)/(d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of
the earth 5.98 x 1024 (in kg), and d is the distance in meters from the Earth's center (stored in variable dist_center)
Sample output with input: 6.3782e6 (100 m above the Earth's surface at the equator)
Acceleration of gravity: 9.81
Answer:
The summary of the given query would be summarized throughout the below segment. The output of the question is attached below.
Explanation:
Given values are:
[tex]G = 6.673e-11[/tex][tex]M = 5.98e24[/tex][tex]accel \ gravity = 0[/tex][tex]dist\ center=float(inp())[/tex]here,
inp = input
By utilizing the below formula, we get
⇒ [tex]\frac{GM}{d^2}[/tex]
Now,
⇒ [tex]accel \ gravity=\frac{G\times M}{dist \ center**2}[/tex]
⇒ print("Acceleration of gravity: {:.2f}".format(accel_gravity))
Consider the following program in which the statements are in the incorrect order. Rearrange the statements so that the program prompts the user to input the height an the radius of the base of a cylinder and outputs the volume and surface area of the cylinder. Format the output to two decimal places.
#include
#include
int main()
{}
double height;
cout << "Volume of the cylinder = "
<< PI * pow(radius, 2.0)* height << endl;
cout << "Enter the height of the cylinder: ";
cin >> radius;
cout << endl;
return 0;
double radius;
cout << "Surface area: "
<< 2 * radius * + 2 * PI * pow(radius, 2.0) << endl;
cout << fixed << showpoint << setprecision(2);
cout << "Enter the radius of the base of the cylinder: ";
cin >> height;
cout << endl;
#include
const double PI = 3.14159;
using namespace std;
Answer:
The arrange code is as follows:
#include<iomanip>
#include<iostream>
#include<math.h>
using namespace std;
const double PI = 3.14159;
int main(){
double height;
double radius;
cout << "Enter the height of the cylinder: ";
cout << endl;
cin >> height;
cout << "Enter the radius of the base of the cylinder: ";
cout << endl;
cin >> radius;
cout << fixed << showpoint << setprecision(2);
cout << "Volume of the cylinder = "<< PI * pow(radius, 2.0)* height << endl;
cout << "Surface area: "<< 2 * radius * + 2 * PI * pow(radius, 2.0) << endl;
return 0;
}
Explanation:
Required
Rearrange the program
There are no one way to solve questions like this. However, a simple guide is as follows:
All header files must be called first (i.e #include....)
Followed by the namespaces (std)
if the program uses constant, the constant must be declared and initialized.
e.g. const double PI = 3.14159;
Next, all variables and must be declared (e.g. double radius)
Next, all inputs must be taken before the values of the variables can be used (e.g. cin >> height;)
If the inputs used prompts, the prompt must be before the inputs.
Next, perform all computations then output the results

For minimization problems, the optimal objective function value to the LP relaxation provides what for the optimal objective function value of the ILP problem?
Answer:
A lower bound on the optimal integer value.
Explanation:
The question is poorly typed. The original question requires the optimal solution of the objective function of a minimization problem
I will answer this question base on the above illustration.
When an objective function is to be minimized, it means that the objective function will take the feasible solution with the least value.
The least value are often referred to as the lower bound.
Ten examples of an interpreter
Answer:
Some popular examples of today's interpreters are:
Interpreter of PythonInterpreter for RubyPerl performerInterpreter for PHPMATLAB UCSD PascalExplanation:
An interpreter executes the commands directly in an object code or a machine code, written in a program or a scripting language.
The Interpreter can be referred to as system software that can read and execute the programme instead of interpreting programmes. This interpretation includes high-level source code, pre-compiled programmes and scripts.
It is important to note that the interpreter translates programme by programme line, meaning that one statement is translated on one go. This feature makes it easy for programmers to check any line on debugging but slows the whole programme running time.
which feature of organisations to manage needs to know about to build and use information system successfully
The correct answer to this open question is the following.
The feature of organizations to manage needs to know about to build and use information system successful is the following.
Managers of successful organizations should know that companies have hierarchies and different structures in which these companies are organized.
Every company use systems and procedures that could be specialized to the degree the company requires. For that system to function, they have to be perfectly interconnected to all the areas of the company. The goal: to maximize efficiency and accomplish the goals.
Systems and procedures should take into consideration the culture and diversity of the workplace. There are interest groups in every organization that have special characteristics and requirements that have to be taken into consideration to create a much better system.
Good managers must be aware of these elements, and the different roles, goals, management styles, tasks, incentives, and departmental structure of the company so the system can better serve the purpose of the entire organization.
(Ramanujan's Taxi) Srinivasa Ramanujan indian mathematician who became famous for his intuition for numbers. When the English mathemematician G.H. Hardy came ot visit him in the hospital one day, Hardy remarked that the number if his taxi was 1729, a rather dull number. To which Ramanujan replied, "No, Hardy! It is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways." Verify this claim by writing a program Ramanujan.java that takes a command-line argument N and prints out all integers less than or equal to N that can be expressed as the sum of two cubes in two different ways. In other words, find distinct positive integers a, b, c, and d such that а3 + b3 = c3 - d3. Hint: Use four nested for loops, with these bounds on the loop variables: 0 < a < 3√N, a < b < 3√N - a3, a < c < 3√N and c < d < 3√N - C3; do not explicitly compute cube roots, and instead use x . x *x < y in place of х < Math.cbrt (y).
$ javac Ramanujan.java
$ java Ramanujan 40000
1729 = 1"3 + 12^3 = 9^3 + 10"3
4104 = 2^3 + 16^3 = 9^3 + 15^3
13832 = 2^3 + 24^3 = 18^3 + 20^3
39312 = 2^3 + 34^3 = 15^3 + 33^3
32832 = 4^3 + 32^3 = 18^3 + 30^3
20683 = 10^3 + 27^3 = 19^3 + 24^3
Answer:
Here the code is given as follows,
Explanation:
Code:
public class Ramanujan {
public static void main(String[] args) {
// check cmd argument
int n = Integer.parseInt(args[0]);
// checking a^3 + b^3 = c^3 + d^3
// outer loop
for (int a = 1; (a*a*a) <= n; a++) {
int a3 = a*a*a;
// no solution is possible, since upcoming a values are more
if (a3 > n)
break;
// avoid duplicate
for (int b = a; (b * b * b) <= (n - a3); b++) {
int b3 = b*b*b;
if (a3 + b3 > n)
break;
// avoid duplicates
for (int c = a + 1; (c*c*c) <= n; c++) {
int c3 = c*c*c;
if (c3 > a3 + b3)
break;
// avoid duplicates
for (int d = c; (d * d * d) <= (n - c3); d++) {
int d3 = d*d*d;

Several families are planning a shared car trip on scenic drives in New Hampshire's White Mountains. To minimize the possibility of any quarrels, they want to assign individuals to cars so that no two members of a family are in the same car. Explain how to formulate this problem as a network flow problem.
Answer:
Following are the response to the given question:
Explanation:
Build a spring, sink, vertices, and vertices for each car for a household. Every unit in the stream is a human. Attach the source from each vertical of a family with such a capacity line equivalent to the family size; this sets the number of members in each household. Attach every car vertices to the sink with the edge of the car's passenger belt; this assures the correct number of people for every vehicle. Connecting every vertex in your household to any vertex in your vehicle with a capacity 1 border guarantees that one family member joins a single car. The link between both the acceptable allocation of people to vehicles as well as the maximum flow inside the graph seems clear to notice.
