In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.

Write a python application to simulate an Online Book Shop. Notes: Option 1 and Option 2 must display the list of books to the user. The Main function accounts for invalid options. Program displays error message for invalid user option, invalid ISBN number or any invalid title.The programmer can create the book title, price, and ISBN information for the books. Each item consists only one string of comma-separated data: book ISBN number, title, and price. A customer can purchase some books either by ISBN number and/or by title. If the user input an invalid number or book title, the program should display an error message. The user can stop shopping with "checkout" option , which triggers the checkout() function that computes the total cost of the books in the cart. A customer will be provided the following menu option while shopping at the book shop: Option 1. Purchase by ISBN: User can purchase a book by its ISBN number. ISBN stands for International Standard Book Number. This is a...

1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed "Invalid input: you must enter asingle number from 1-6." Example:Enter a...

PrimeAA.java Write a program that will tell a user if their number is prime or not. Your code will need to run in a loop (possibly many loops) so that the user can continue to check numbers. A prime is a number that is only divisible by itself and the number 1. This means your code should loop through each value between 1 and the number entered to see if it’s a divisor. If you only check for a small handful of numbers (such as 2, 3, and 5), you will lose most of the credit for this project. Include a try/catch to catch input mismatches and include a custom exception to catch negative values. If the user enters 0, the program should end. Not only will you tell the user if their number is prime or not, you must also print the divisors to the screen (if they exist) on the same line as shown below AND give a count of how many divisors there are. See examples below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output...

Java Programming: Question 12 Not sure how to do this question. Help of any input and output would be appreciated.

Prime factors of an integer \( n \) are a set of prime numbers that can be multiplied together to obtain \( n \). Write a proHide Transcribed Text Prime factors of an integernare a set of prime numbers that can be multiplied together to obtainn. Write a program that asks the user to enter a number and displays the prime factors ordered from smallest to largest. If the number entered by the user is less than 2 then there are no prime factors and the message "No prime factors" should be displayed. The following algorithm can be used to discover the prime factors: - initialize factor to 2 - while factor is less than or equal tondo: ifnis evenly divisible by factor then - conclude that factor is a factor ofn- dividenby factor using floor division else: - increase factor by 1 Adapt the algorithm so it can be used to print out the prime factors of a number. Notes: - You can assume that the number entered by the user will be an integer number. - The output must be in the format shown in the...

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

In C# code: Write a program that will help an elementary schoolstudent learn multiplication. Use a Random object to produce two positive one-digitintegers. The program should then prompt the user with a question, such asHow much is 6 times 7 The student then inputs the answer. Next, the program checks the student’s answer. Ifit’s correct, display the message "Very good!" and ask another multiplication question.If the answer is wrong, display the message "No. Please try again." and let the studenttry the same question repeatedly until the student gets it right. A separate methodshould be used to generate each new question. This method should be called oncewhen the app begins execution and each time the user answers the question correctly.Program will stop any time students enter -1. One problem in CAI environments is student fatigue. This can be reduced by varyingthe computer’s responses to hold the student’s attention. The program should usevarious comments to be displayed for each...

JAVA PPROGRAM ASAP Please create this program ASAP BECAUSE IT IS MY LAB ASSIGNMENT #2 so it passes all the test cases. The program must pass the test case when uploaded to Hypergrade. Chapter 9. PC #8. 8. Sum of Numbers in a String (page 610) Write a program that asks the user to enter a series of numbers separated by commas. Here are two examples of valid input: 7,9,10,2,18,6 8.777,10.9,11,2.2,-18,6 The program should calculate and display the sum of all the numbers. Input Validation 1. Make sure the string only contains numbers and commas (valid symbols are '0'-'9', '-', '.', and ','). 2. If the string is empty, a messages should be displayed, saying that the string is empty.

Write a program that asks the user to enter 10 numbers, that range from 10-100. Make sure that you do not accept any numbers less than 10, if a user enters a number that is less than 10 then ask him again. Once the user enters all 10 numbers, sort the numbers entered in ascending order and print them out. CSharp
