Solved in 2 steps
- In java Develop a function that takes two integers and returns the sum of the values from the first to the second (the two inputs may be in any order). Call the function at least twice with different arguments Develop a void function PrintLineOfChar that accepts a single character and an integer. The function prints a single line of the character repeated the integer number of times. Call the function at least twice with different arguments.Write a C++ program that will display multiple-choice trivia questions, accept the user's answers, and provide a full key and a score at the end. Design and implement a class called Question. The Question class contains the following information: a stem (the text of the trivia question) an array of 4 multiple choice answers (the text of each possible answer) the letter of the correct answer (A, B, C, or D), called the key. This class will be used to represent trivia questions in a trivia game. The following operations should be available for Question objects (use the provided names). Construct a Question with no values (use empty strings for stem and answers and 'X' for the key). Construct a Question given its 3 components (). setStem: Set the stem question. getStem: Return the stem question. setAnswers: Set the 4 answers given an array. The answers will NOT include the letter (A, B, C, or D). getAnswer(i): Return the single answer at index i. setKey: Set the key letter. getKey:…Java Programming 13: AcctNumsIn.txt has been provided and contains a list of at least 15 six-digit account numbers. Implement the ValidateCheckDigits program to read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file (AcctNumsOut.txt), each on its own line. ValidateChecksDigits.java: import java.nio.file.*; import java.io.*; import java.nio.channels.FileChannel; import java.nio.ByteBuffer; import static java.nio.file.StandardOpenOption.*; public class ValidateCheckDigits { public static void main(String[] args) { Path fileIn = Paths.get("/root/sandbox/AcctNumsIn.txt"); Path fileOut =…
- 1. Suppose you are a student of East West University. You have to design a multithreadedsystem in java for your CSE110 course. So, you are assigned a job with followingdescriptions. You have to design a class NumberComputator which has a functionprintComposite(int n) that can take a parameter N and print the composite numberfrom 1 to nth term. Composite numbers are the number that are not prime number.Again, create two thread class (ThreadOne, ThreadTwo) by extending the Threadclass so that all of the thread should call the method “printComposite(int n)” of theNumberComputator class. Again, write a main java class named“MultiProgrammingDemo” with a main method that instantiate two objects of twothreads(ThreadOne, ThreadTwo).Your task is to process and run two threads simultaneously in the main method byconsidering the fact that when one thread printing with the printComposite(n)function the other threads must be wait for the completion of the work the initial thread.Design a JAVA…Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing. The String class has a lot of functions and continues to grow. See https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create a java program that when give a sentence will replace the first occurrence of NUST with Namibia University of Science and Technology. Sample run 1: --- Input ---Welcome to my NUST --- Expected output (text)---Welcome to my Namibia University of Science and Technology. Sample run 2: --- Input ---The nust is a great institution of high learning. --- Expected output (text)---The Namibia University of Science and Technology is a great institution of high learning. Sample run 3: --- Input ---The NuSt was renamed from Polytechnic Of Namibia under Act No. 7 of 2015. --- Expected output (text)---The Namibia University of Science and…Write a function in Java. output the following things should be output ask for the members from specific faculty output the top 5 scores members Recommend line up of top members OR members with similar interests list of members over a certain age Use arraylists arraylist name: groupName
- Create a java program that uses classes (instance variables, methods, and constructors) and objects to do the following: • accepts three numbers computes the SUM of all three numbers and determines whether the SUM is odd or even • determine which is the highest and lowest number • Sort the three numbers in ascending order.• Sort the three numbers in descending order.Java considers the String data type as non-primitive, because it contains a sequence of characters and hence there is a predefined class called String dedicated to String processing. The String class has a lot of functions and continues to grow. See https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create a java program that when give a sentence will replace the first occurrence of NUST with Namibia University of Science and Technology. Sample run 1: Enter a sentence: Welcome to my NUST. Output: Welcome to my Namibia University of Science and Technology. Sample run 2: Enter a sentence: The nust is a great institution of high learning. Output: The Namibia University of Science and Technology is a great institution of high learning.Java program Implement getName : returns the name of the student in the following format {lastname}, {firstname} increaseAge : increase age by one, this returns nothing toString : returns the details of a student format is lastname,firstname,age,minor or adult
- UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.2. Write a Java program that would resemble a payroll system. An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window. Design your own input/output windows.Write a code in C# that finds the smallest ID of a subject taught by the most teachers without using any Linq Lib's elements, such as OrderBy, OrderByDescending, etc: We know about the teachers at a school, what lessons they have and when. We identify the teachers, the subjects, the days of the week and the time slots in a day with ID numbers. Write a program that determines the subject that is taught by the most teachers.InputThe first line of the standard input contains the count of lessons (1≤L≤800), the count of teachers (1≤N≤100), the count of subjects (1≤M≤100), the ID of a teacher (1≤T≤N) and the ID of a day (1≤D≤5), separated by spaces. The next L lines contain 4 integers separated by spaces: the ID of the teacher (1≤TID≤N), the ID of subject taught (1≤TS≤M), day (1≤Day≤5), and time slot (0≤Time≤8) of a lesson. For example, 3 7 2 1 means that the third teacher teaches the seventh subject on the second day of the week in the first time slot.OutputThe first line of the standard…
