Question

(InputMismatchException) and (ArrayIndexOutOfBoundsException): Using the two arrays shown below, write a program that prompts the user to enter an integer between 1 and 12 and then displays the months and its number of days corresponding to the integer entered. 1. Your program should display “Wrong number - Out of Bounds” if the user enters a wrong number by catching ArrayIndexOutOfBoundsException. 2. Also the program should display “Mismatch – not a number” if the user enters anything other than an integer by catching InputMismatchException. 3. The program should not terminate abnormally, i.e. until the user enters the right number. String[] months = {“January”, “February”, “March”, “April”, “May”, “June”, “July”, “August”, “September”, “October”, “November”, “December”}; int[] dom = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};

Code:

import java.util.*;

class Array{
   public static void main(String[] args){
       Scanner sc = new Scanner(System.in);
  
       String[] months = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
       int[] dom = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};

       System.out.println("enter an integer between 1 and 12? ");
       try{
           int mon = sc.nextInt();
           System.out.println("Month and its number of days are: "+ months[mon-1] + " " + dom[mon-1]);
       }
       catch(InputMismatchException ex){
           System.out.println("Mismatch – not a number");
       }
       catch(ArrayIndexOutOfBoundsException ex){
           System.out.println("Wrong number - Out of Bounds");
       }
   }
}
