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. import java.util.*; public class EvenEntryLoop { public static void main (String args[]) { // Write your code here } }
Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.
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): -1
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!!
Java Programming: Write a program that reads five integer values from the user, then analyzes them as if they were a hand of cards. When your program runs it might look like this (user input is in orange for clarity): Enter five numeric cards, no face cards. Use 2 - 9. Card 1: 8 Card 2: 7 Card 3: 8 Card 4: 2 Card 5: 9 Pair! (This is a pair, since there are two eights). You are only required to find the hands Pair and Straight.
Write an application that reads an integer value from the user and prints the sum ofall even integers between 2 and the input value, inclusive. Print an error message ifthe input value is less than 2. Use Java. Sample Run Examples: Example 1:the user enters 14Output: Sum: 56Example 2:the user enters 1Output: Error number must be greater than 1
ISP- Java A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); Your program must define and call a method: public static double stepsToMiles(int userSteps) Ex: Ex: If the input is: 8790 the output is: 4.40
