To write a java program that display inputs of an integer, n, from the command line and displays the string "1 + 2 + 3 + 4 + ... + n = sum." For example, if the command-line argument is 7, the output should be: The sum of (1 + 2 + 3 + 4 + 5 + 6 + 7) = 28 Make sure the number entered on the command line is positive.

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 } }
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
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!!
A number (or a word) is called palindrome if it may be read in the same way from left toright as right to left (e.g. 131 and 56965).Write a Java application that reads from the user a positive integer consists of exactly 5 digits.Then separates the integer into its individual digits and prints a message indicating if thisinteger is palindrome or not.The program should print an error message if the number is not positive and not composed of 5digits.Hint: Use % 10 in order to extract the last digit of an integer and / 10 in order to eliminatethe last digit of an integer. For example, 942 % 10 = 2 and 942 / 10 =94.Sample run1:Enter a positive integer (5 digits): -12345The number should be positive and of 5 digitsSample run2:Enter a positive integer (5 digits): 123The number should be positive and of 5 digitsSample run3:Enter a positive integer (5 digits): 1232112321 is a palindromeSample run4:Enter a positive integer (5 digits): 1234512345 is not palindrome
Write a java program that prompts the user to enter two integers, intLeft and intRight, taking into consideration that intRight should be greater than intLeft. The program should display all the numbers divisible by 5 and all the numbers divisible by 7 between intLeft and intRight exactly as displayed in the sample runs below: Sample Run 1:Enter First Integer: 1Enter Second Integer: 20Numbers Divisible by 5 : 5, 10, 15, 20, Numbers Divisible by 7 : 7, 14, Sample Run 2:Enter First Integer: 10Enter Second Integer: 50Numbers Divisible by 5 : 10, 15, 20, 25, 30, 35, 40, 45, 50, Numbers Divisible by 7 : 14, 21, 28, 42, 49, Sample Run 3:Enter First Integer: 10Enter Second Integer: 5intRight should be greater than intLeft
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.

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…
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
Write a program to compute the sum of the first N Fibonacci numbers, where N is an integer that is input by the user. Once it computes the sum, the program will prompt the user for a new value of N. The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer. Language: Java Additionally: The first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Must use For loops, can use while loops. Sample Output: Welcome to the Fibonacci AdderTo quit, end a non-integer number or string How many Fibonacci numbers should be summed? >> 10The sum of the first 10 Fibonacci numbers is: 88 How many Fibonacci numbers should be summed? >> xxx Thank You for Using the Fibonacci Adder
Write a java program that accepts a 5 integer number (from the user) and calculates the sum of all its digits. For example, integer 12345 must display 15 (i.e. 1 + 2 + 3 + 4 + 5)
