The while loop makes multiple attempts to read a nonnegative integer from input into userAge. Use multiple exception handlers to: Catch an InputMismatchException, output "Unexpected input: The UserAge program quits", and assign retry with false. • Catch an Exception and output the message of the Exception. End each output with a newline. Ex: If the input is 44, then the output is: Valid input: User's age is 44 Ex: If the input is L, then the output is: Unexpected input: The UserAge program quits Ex: If the input is -65 44, then the output is: User's age must be nonnegative Valid input: User's age is 44 1 import java.util.Scanner; 2 import java.util.InputMismatchException; L234567800 4 public class UserAge { 9 10 AWNHO 11 12 13 14 15 16 17 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int userAge; boolean retry = true; while (retry) { try { userAge = scnr.nextInt (); if (userAge< 0) { throw new Exception ("User's age must be nonnegative"); }

4. Identify the benefits of using both Accessor and Mutator in Java.  PS: Please answer it correctly and less confusing.

import java.util.Scanner ; //This program enables the user enters 10 int between -100 and 100 //then a menu is presented to the user to choose an operation to be //performed on the entered numbers. //operations: add all numbers and display their total //display the average of the numbers //find and display all negative numbers //find and display odd numbers //display all numbers in reverse order //display all 5 multiples public class OPonArrays { public static void main (String [] main) { int SIZE = 10; int [] nums= new int [SIZE]; Scanner KB = new Scanner(System.in); // populate the array for(int i = 0; i < 10; i++) { System.out.println("please enter a number between -100 and 100"); nums[i] = KB.nextInt(); } //display all elments for(int i = 0; i < 10; i++) { System .out.println(nums[i]); } fix the error

Math 130 Java Programming  Does my code pass the requirements? May I have more explanation? Does my code compile correctly? Is my code readable? Is my code well commented? How may I better organize my code? Are there whitespaces to appropriate help separate distinct parts?     My code: import java.util.Scanner; public class TicketSale  { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in);   //Prompt user to input the number of Adult tickets to purchase System.out.print("Please enter number of adults:"); //Prompt user to input the number of Adult tickets to purchase int adults = keyboard.nextInt();   //Prompt user to input the number of Children tickets to purchase System.out.print("Please enter number of children:");    //Prompt user to input the number of Children tickets to purchase int children = keyboard.nextInt();   //Calculate and display the total cost for adults and children System.out.print("Your total cost for " + adults +…
