Question

12.3 Write an application named BadSubscriptCaught in which you declare an array of 10 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 should also display an error message. Save the file as BadSubscriptCaught.java. Need code HTML/JavaScript to execute and run in Internet Explorer for testing.

Explanation / Answer

import java.util.Scanner;
public class BadSubscriptCaught {
   private static Scanner sca;

   public static void main(String arg[])
   {
       sca = new Scanner(System.in);
       String[] names={"John","Peter","Mac","Max","Mark","Steve","Thomas","Kit","Barak","Jams"};
       System.out.println("Enter the position of Name : ");
       int position=sca.nextInt();
       try
       {
           System.out.println(names[position]);
       }catch(ArrayIndexOutOfBoundsException e)
       {
           System.out.println(e);
       }
   }
}

Enter the position of Name :
12
java.lang.ArrayIndexOutOfBoundsException: 12
