Question

Write an application in which you declare an array of eight first names. Write a try block in which you prompt the user for an integer and display the name in the requested position. Create a catch block that catches the potential ArrayIndexOutOfBoundsException thrown when the user enters a number that is out of range. The catch block also should display the error message Subscript out of range.

import java.util.*;
public class BadSubscriptCaught
{
   public static void main(String[] args)
   {
      String[] names = {"Ariel", "Brad", "Clifford", "Denise", "Emily",
        "Fred", "Gina", "Henry"};
      Scanner keyboard = new Scanner(System.in);
      int number;
   
      // your code here
   }
}

Answer 1

import java.util.Arrays;
import java.util.Scanner;
public class BadSubscriptCaught {

   public static void main(String[] args)
   {
   String[] names = {"Ariel", "Brad", "Clifford", "Denise", "Emily",
   "Fred", "Gina", "Henry"};
   Scanner keyboard = new Scanner(System.in);
   int number;
   System.out.println("Enter index position: ");
   number=keyboard.nextInt();
     
   try{
       System.out.println("Name is: "+names[number]);
   }
   catch(ArrayIndexOutOfBoundsException e)
   {
       System.out.println("Subscript out of range");
   }
   }
}

Enter index postion: Enter valid range
