- java Write an application that asks a user to type an even number or the sentinel value 999 to stop. When the user types an even number, display the message “Good job!” and then ask for another input. When the user types an odd number, display an error message, "x is not an even number", and then ask for another input. When the user types the sentinel value 999, end the program. The EvenEntryLoop program displays the proper message for each input. Checks Test CaseIncomplete Single even number input 2, 999, test 1 Test CaseIncomplete Single even number input 5, 999, test 2 Test CaseIncomplete Multiple mixed number input 13, 3487, 987, 1234, 999 import java.util.*; public class EvenEntryLoop { public static void main (String args[]) { // Write your code here } }Write an java application that allows a user to enter any number of student quiz scores, as integers, until the user enters 99. If the score entered is less than 0 or more than 10, display Score must be between 10 and 0 and do not use the score. After all the scores have been entered, display the number of valid scores entered, the highest score, the lowest score, and the arithmetic average. import java.util.*; public class QuizScoreStatistics { public static void main (String args[]) { // Write your code here } }JAVA Write a program that allows a user to enter a series of numbers and displays frequency of each number. Implement the following: 1. The user can enter a maximum of 20 numbers or enter-1 to end the series (i.e. they can enter less than 20 numbers by entering -1) 2. Only numbers between 0-9 is allowed (or -1 ); if the user enters a number outside the valid input, inform the user and ask them to enter a valid number; keep repeating till a valid input is entered. Implement reading and validation of user input in a class "UserInput" - it should have a static method getNextNumber() that returns a valid integer. In your main program, use UserInput.getNextNumber() to read a valid input. 3. Display the frequency of each number in the output, in the following format Number: Frequency For example, if the user input is 0,0,1,2,2,4,5,8,8,8,9,9, -1 the output will be: 0: 2 1; 1 2: 2 3: 0 4: 1 5: 1 6: 0 7: 0 8: 3 9: 2
- For Java Write an application that prompts a user for two integers and displays every integer between them. Display There are no integers between X and Y if there are no integers between the entered values. Make sure the program works regardless of which entered value is larger. An example of the program is shown below: Enter an integer >> 12 Enter another integer >> 20 The numbers between 12 and 20 include: 13 14 15This needs to be done in Java! A palindrome is a sequence of characters that reads the same backward as forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 4554, and 11611. Write an application that reads in a five-digit integer and determines whether it’s a palindrome. If the number is not five digits long, display an error message and allow the user to enter a new value. Algorithm: Create two variables number and digits Capture the 5 digit number. Check If the number is not 5 characters long, display a message Use: while (digits != 5) Use if else statements: if (number < 100000) Set digits to 5 if > 9999 If not display statement letting the user know to enter correct 5 digit number Separate each digit: int digit1 = number / 10000; int digit2 = number % 10000 / 1000; int digit4 = number % 10000 % 1000 % 100 / 10; int digit5 = number % 10000 % 1000 % 100…Write a java program to create a "Calculator Quiz-Test" application to perform addition of three random questions. When the program starts your application should display 2 random numbers ranging from 1-100 and ask the user to enter the addition of these 2 numbers (similarly you have to create 2 more sets of questions) and finally you should display the number of correct and incorrect questions and display the total marks as well. A correct answer will earn 10 marks and an incorrect answer will get - 5 (negative mark). When the program ends you should display the following, ) Number of correct and incorrect questions 2) Total marks obtained 3) The answer for all generated questions.
- in java pls: You have been asked to produce a report for a hardware store The name for each item is widget with the word designating the number of the widget. There are ten widgets in all. Your program will ask the user for the range of the cost for items, range of the price of the items in doubles. The range for the quantity in stock will be between 0 and 9999 as an int. Your program will randomly generate the cost of the items, price of the items the number in stock for this sample report based upon the ranges entered. Make sure the price of the item is greater than the cost. Profit is calculated as (price- cost) * in stock. Any time quantity falls below 25 the reorder column will display Yes, otherwise it will display No. Your chart will generate data for ten items and the chart will look like the one below. Part QuantityName Cost Price in Stock…In Java code Write a program that takes in an integer in the range 11-100 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical.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 =…
- A Newton number is a 4-digit integer number for which the sum of its digits to power 4 is equal to the number itself. Example of a Newton number is 1634 since: 1634 1*1*1*1+6*6*6*6+3*3*3*3+4*4*4*4 which is: 1+ 1296+256+81. Write a Java program that checks whether or not a number is a Newton number. Sample Run1: Enter an integer number of 4 digits: 3712 3712 is not a Newton number Sample Run2: Enter an integer number of 4 digits: 1634 1634 is not a Newton number Sample Run2: Enter an integer number of 4 digits: 234 Invalid input!!write a java program A twin prime is a prime number that is either 2 less or 2 more than another prime number. For example (41, 43) are both primes and are twin primes because 41 + 2 = 43. Write a program that asks the user to enter a positive number and checks if this number is prime. If the number is prime then the program must check if it has a twin prime. So if n is prime, then n - 2 or n + 2 should be checked. The program repeats until the user enters -1. Sample Run: Enter a positive integer (-1 to end): -5 Invalid Number Enter a positive integer (-1 to end): 61 61 is prime 59 and 61 are twin prime Enter a positive integer (-1 to end): 137 137 is prime 137 and 139 are twin prime Enter a positive integer (-1 to end): 30 30 is not prime Enter a positive integer (-1 to end): 23 23 is prime 23 does not have a twin prime Enter a positive integer (-1 to end): -1Write a C# program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average. An example of how the results should be output is as follows: Test # 0: 89 From average: 6 Test # 1: 78 From average: -5 Also like: Test # 0: 74 From average: 13.375 Test # 1: 65 From average: 4.375
