- Integer userValue is read from input. Assume userValue is greater than 10000 and less than 99999. Assign ten Thousands Digit with userValue's ten thousands place value. Ex: If the input is 17598, then the output is: The value in the ten thousands place is: 1 1 import java.util.Scanner; 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 14 15} public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int userValue; int tenThousandsDigit; } userValue = scnr.nextInt(); *Your code goes here */ System.out.println("The value in the ten thousands place is: " + tenThousands Digit);Print "userNum1 is negative." if userNum1 is less than 0. End with newline. Assign userNum2 with 4 if userNum2 is greater than 9. Otherwise, print "userNum2 is less than or equal to 9.". End with newline. 1 import java.util.Scanner; 2 public class UserNums { public static void main (String [] args) { int userNum1; int userNum2; 4 6. 7 Scanner input userNum1 = 8. = new Scanner(System.in); input.nextInt(); input.nextInt(); 9. 10 userNum2 11 12 V* Your code goes here */ 13 System.out.println("userNum2 is " } 14 + userNum2); 15 16 17 }Write an application that prompts a user for the number of years the user has until retirement and then the amount of money the user can save annually. If the user enters 0 or a negative number for either value, reprompt the user until valid entries are made. Assume that no interest is earned on the money. Display the amount of money the user will have at retirement. import java.util.Scanner; public class RetirementGoal { public static void main (String[] args) { // your code here } }

- This is the question - Write an application that prompts a user for a month, day, and year. Then display the appropriate message: Y is not this year M was a month earlier this year M is a month later this year M is this month This is the code I have for it so far - import java.util.*; import java.time.*; public class PastPresentFuture { public static void main (String args[]) { LocalDate today = LocalDate.now(); LocalDate enteredDate; int mo, da, yr; int todayMo, todayDa, todayYr; Scanner input = new Scanner(System.in); System.out.print("Enter a month >> "); mo = input.nextInt(); System.out.print("Enter a day >> "); da = input.nextInt(); System.out.print("Enter a year (four digits) >> "); yr = input.nextInt(); } }Write an java application that allows a user to enter any number of student quiz scores, as integers, until the user enters 99.

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 } }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. import java.util.Scanner; public class LabProgram {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);String userString;// Add more variables as needed userString = scnr.next();
