Explanation:
Sum of Primes JAVA project
read 2 strings from the command line; each string will contain an integer. let's call those integers, num1 and num2. write a loop that goes from num1 and num2 looking for prime numbers. if a number if prime then store it in an array of integers, pass this array to a method that returns the sum of all the numbers in the array; you will also need to tell this method how many numbers are in the array. output only the sum of primes. you may assume a maximum of not more than 1000 numbers in the array.
*CODE*
import java.util.*;
class SumPrimes {
// go thru the array primes which has size elements
// total the integer values in primes
// return this total
// the first argument is the array of prime numbers
// the second argument is the number of primes in this array
public static int sumArray(first argument, second argument) {
}
// this method takes an integer, n, and determines if it is prime
// returns true if it is and false if it isn't
// a number is prime if it is only evenly divisible by 1 and itself
// 1 is NOT considered prime
static boolean isPrime(int n) {
// Corner case
if (n <= 1)
return false;
// Check from 2 to n-1
for (int i = 2; i < n; i++)
if (n % i == 0)
return false;
return true;
}
public static void main(String[] args) {
// define the constant MAX which represents the largest size of the primes array
int num1, num2, numPrime = 0;
// declare an array of the proper data type and size
// convert 1st command line argument from a string to an integer
num1 = Integer.parseInt(args[0]);
// get num2 from the command line
// loop through all integers from num1 to num2
// store those that are prime in the primes array
// keep track of the number of primes - numPrime
// output the sum of all the primes
System.out.println(sumArray(primes, numPrime));
}
}
Answer:
Explanation:
The following code is written in Java and creates the necessary code so that two int inputs are read and looped through all the numbers between them to find all the primes. These primes are counted and summed. Finally, printing out the sum and the number of primes found to the console.
import java.util.ArrayList;
import java.util.Scanner;
class SumPrimes{
public static void main(final String[] args) {
Scanner in = new Scanner(System.in);
ArrayList<Integer> primes = new ArrayList<>();
int num1, num2, numPrime = 0;
System.out.println("Enter number 1:");
num1 = in.nextInt();
System.out.println("Enter number 2:");
num2 = in.nextInt();
for (int x = num1; x <= num2; x++) {
if (isPrime(x) == true) {
primes.add(x);
numPrime += 1;
}
}
System.out.println("There are " + numPrime + " primes in the array.");
System.out.println("Their sum is " + sumArray(primes));
}
public static int sumArray(ArrayList<Integer> arr) {
int sum = 0;
for (int x: arr) {
sum += x;
}
return sum;
}
static boolean isPrime(int n) {
if (n <= 1)
return false;
for (int i = 2; i < n; i++)
if (n % i == 0)
return false;
return true;
}
}

Write a program in which will use some of the built-in METHODS as it relates to the use of Strings. 1) The program will ask the user the following prompts: Please enter your first name and their last name, separated by a space. This program will then read-in the user's response using Scanner. You must separate the string input entered by the user into two strings via substrings. Substring one will store the first name and Substring two will store the last name respectively. ***hint this can be accomplish using the indexOf() to find the position of the space. Your program must display/output the number of characters in each name, as well as the user's initials that was entered. You must check and trim all extra white spaces before and after the string entered by the user. Incorporate and loop to have this program ask this user if they would like to execute the program again by prompting and requesting a Y for Yes and a N for No. This prompt should ignore upper or lower case entries. The initials are the first letter of the first name together with the first letter of the last name. Hello their Louis I have your first name as Louis, which has 5 characters Hello again Louis I have your last name as Henry, which has 5 characters Did you know that your initials are LH Do you wish to continue (Y)Yes or (N)No
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
char cont = 'Y';
while(cont == 'Y'){
System.out.print("Name: ");
String name =input.nextLine();
String names [] = name.split(" ");
names[0] = names[0].replaceAll("\\s", "");
names[1] = names[1].replaceAll("\\s", "");
System.out.println("Hello their "+names[0]+", I have your first name as "+names[0]+", which has "+names[0].length()+" characters ");
System.out.println("Hello again "+names[0]+", I have your last name as "+names[1]+", which has "+names[1].length()+" characters ");
System.out.println("Did you know that your initials are "+names[0].charAt(0)+names[1].charAt(0));
System.out.print("Continue (Y)Yes or (N)No: ");
cont = Character.toUpperCase(input.next().charAt(0));
input.nextLine();} }}
Explanation:
This initializes a character variable cont to Y
char cont = 'Y';
This is repeated as long as cont is Y
while(cont == 'Y'){
This prompts the user for name
System.out.print("Name: ");
This gets the name from the user
String name =input.nextLine();
This splits the name into the array of two elements (first name and last name)
String names [] = name.split(" ");
This remove all whitespace from the first name
names[0] = names[0].replaceAll("\\s", "");
This remove all whitespace from the last name
names[1] = names[1].replaceAll("\\s", "");
This prints the details of the first name
System.out.println("Hello their "+names[0]+", I have your first name as "+names[0]+", which has "+names[0].length()+" characters ");
This prints the details of the last name
System.out.println("Hello again "+names[0]+", I have your last name as "+names[1]+", which has "+names[1].length()+" characters ");
This prints the initials
System.out.println("Did you know that your initials are "+names[0].charAt(0)+names[1].charAt(0));
This prompts the user to continue or not
System.out.print("Continue (Y)Yes or (N)No: ");
This gets the user response
cont = Character.toUpperCase(input.next().charAt(0));
input.nextLine();} }

The different between Del key and BKSE key
Answer and Explanation:
I believe you are referring to Backspace and Del keys, which are the keys of a computer keyboard. In this case, the difference between them is quite simple and easy to understand. These two keys are used to delete characters, however, the Backspace key is capable of deleting characters that are to the left of the cursor (the dash that appears blinking when you are typing). Del Key, in turn, is able to delete the characters to the right of the cursor.
What are Render Modes? How different render modes can be used in different contexts?
Answer:
Rendering is the process that allows obtaining digital images taken from the three-dimensional model, through dedicated software. These images are intended to photorealistically simulate environments, materials, lights, objects in a project and a 3D model. In Computer Graphics Imagery , this process is developed in order to imitate a 3D space formed by polygonal structures, light behavior, textures, materials (water, wood, metal, plastic, cloth, etc.) and animation, simulating environments and credible physical structures. One of the most important parts of the programs dedicated to Computer Graphics Imagery are the rendering engines, which are capable of performing complex techniques or algorithms such as radiosity, raytrace (ray tracer), alpha channel, reflection, refraction or global illumination.
Explanation:
Rendering is a complex calculation process developed by a computer equipment designed to generate a 2D image from a 3D scene. Real-time rendering is preferably used in games and interactive graphics, it is made up of images or animations rendered at a speed that makes the fact that the computer takes time to calculate them imperceptible to the end user, therefore there will be graphic hardware dedicated to ensure rapid image processing. Offline rendering is used in those cases in which a very high speed of use of the images created is not so important, as it happens in animation works or those whose complexity and level of photorealism are much higher. Another of the applications of 3D rendering is in the world of graphic design, since it gives the designer an almost unlimited range of perspectives on the object he is designing. In addition to this, it allows a complete redesign from an initial image. Thus, designers have a tool that allows them to unleash their imagination.

Write a Python programs to do frequency counting of the sum of two dice. Your function should accept an integer n parameter to run n trials (i.e., multiple rollings of the two dice); You can use the Python function randrange(1, 7) to simulate the roll of one die; After running the n trials, your function should return the sum of two dice that occurs most frequently.
Answer:
Explanation:
The following program uses Numpy import to detect the frequency of all the elements in an array and ouput the one that appears the most. The function creates random dice rolls and adds them to the array, looping the number of times that the trials parameter states. Then finally printing out the original array and the sum that appeared the most frequently.
from random import randrange
import numpy as np
def highestFrequency(trials):
products = []
for x in range(trials):
product = randrange(1, 7) * randrange(1, 7)
products.append(product)
x = np.array(products)
print("Original Array: " + str(list(products)))
print("Most frequent value in the above array:")
print(np.bincount(x).argmax())
highestFrequency(7)
Pendant Publishing edits multi-volume manuscripts for many authors. For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work.

Write a program that asks the user for an integer between 0 and 100 that represents a number of cents. Convert that number of cents to the equivalent number of quarters, dimes, nickels, and pennies. Then output the maximum number of quarters that will fit the amount, then the maximum number of dimes that will fit into what then remains, and so on. If the amount entered is negative, write an error message and quit. Amounts greater than 100 are OK (the user will get many quarters.) Use extended assembly instructions and exception handler services. Enter number of cents: 67 Number of quarters:2 Number of dimes :1 Number of nickels :1 Number of pennies :2
Solution :
import [tex]$\text{math}$[/tex]
#First we need to define the value of each coin
[tex]$\text{penny=1}$[/tex]
[tex]$\text{nickel}$[/tex] = 5
[tex]$\text{dime}$[/tex] = 10
[tex]$\text{quarter}$[/tex] = 25
#Here we define [tex]$\text{the variables}$[/tex] to hold the [tex]$\text{max}$[/tex] number of each coin

if [tex]$\text{cents}$[/tex] >= 10:
dimes = cents/dime
[tex]$\text{cents}$[/tex] =[tex]$\text{cents}$[/tex] % dime
if [tex]$\text{cents}$[/tex] >= 5:
nickels =[tex]$\text{cents}$[/tex] /nickel

Suppose that the following statement is included in a program. import static
java.lang. Math.*; After this statement, a static method of the class Math can be called
using just the method name.
A. True
B. False
Answer:
True
Explanation:
The class Math include mathematical functions such as sin(), cos(), tan(), abs(), etc
If the given statement is not written, each of the math function will be written as (take for instance, the sin() function):
Math.sin()
But after the statement has been written (it implies that the Math library has been imported into the program) and as such each of the mathematical function can be used directly.
So instead of Math.sin(), you write sin()
