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 u

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 } }
IN JAVA. Write a program that takes in an integer in the range 20-98 as input. The output is a countdown starting from the integer, and stopping when both output digits are identical. Ex: If the input is: 93 the output is: 93 92 91 90 89 88 Ex: If the input is: 77 the output is: 77 Ex: If the input is: 15 or any number not between 20 and 98 (inclusive), the output is: Input must be 20-98
in Java Write a program that establishes two savings accounts with saver1 having account number10002 with an initial balance of $2,000, and saver2 having account 10003 with an initialbalance of $3,000. Set a common rate of interest at 5% per year. At the end of each month,update the balance by adding one month’s interest to the balance, so that the balancecompounds monthly. Print an output that displays the month number and the account numberand the balance for each of the two accounts. Use month 0 to display the initial balances, month1 to display the balances after the first month’s interest, and so on. At the end of the year,display the total balance for both accounts combined, like this:Output:Monthly balances for one year with 0.05 annual interest:Month Account # Balance Account # Balance----- --------- ------- --------- ------- 0 10002 2000.00 10003 3000.00 1 10002 2008.33 10003 3012.50 2 10002 2016.70 10003 3025.05 3 10002 2025.10 10003 3037.66 4 10002 2033.54 10003 3050.31 5…
In Java for zybooks ,Lab 3.27, Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name.
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
Write a Java program that prompts user for a positive integer ranging between 0-99999. The program shallread the input as int; compute and print the sum of all its digits. Your program needs to perform inputvalidation and exit the program if the input data type is incorrect. For example,Enter a positive integer: 12345The sum of all digits is: 15
Java Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. For coding simplicity, output a space after every integer, including the last. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first.
Write a program CheckDigit.java that takes a 12 or 13-digit long as a command-line argument and displays the digit computed as follows: Take for an example the number 048231312622 Sum every other digit of the code, starting from the right. In the example, that is 2 + 6 + 1 + 1 + 2 + 4 = 16. Discard the tens digit and keep the ones digit, 6. Start with the second to last digit and do the same thing. Sum the digits, discard the tens digit and keep the ones digit. In this example this is 2 + 2 + 3 + 3 + 8 + 0=18. Discarding the 10 leaves 8. Multiply this number by 3 and again discard the tens digit. 8×3 = 24, leaving 4. Add the numbers from steps 1 and 2. Again drop the tens digit. 6 + 4 = 10, leaving the digit 0 (zero). Hint 1: the maximum value that can be stored in an integer variable is 2147483647 which is only 10 digits long. To read a 12 or 13-digit integer from command line argument you will need to store it in a long variable. Use: long number =…
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 } }
