Question

Create a method that returns the third character from the String word. Be sure to use a try catch block and use the appropriate exception to deal with indexes out of a String’s bound: StringIndexOutOfBoundsException. Return the character 'x' (lowercase) when this exception is caught. Do not use if statements and do not use the general exception handler Exception.

Examples:

thirdLetter("test") -> 's'
public char thirdLetter(String word) 

{

}

​should return the char 'r'

Answer 1

Coding

import java.util.Scanner; //it is for user input
public class Simple
{
public static char thirdLetter(String words)//our static function which will get array string from main method
{
try//try catch block if any error will come it will redirect to catch
{
return(words.charAt(2));
}
catch(StringIndexOutOfBoundsException siobe)
{
System.out.println("invalid input No characher on third position");//output message if
return (' ');//it will return null value in that case
}

}

   public static void main(String[] args)
   {
   Scanner sc = new Scanner(System.in);
   System.out.print("Please Enter the String ::");//output message for print
   String word = sc.nextLine();//get string value from word
   System.out.println("Third Letter is ::"+thirdLetter(word));//here third letter
   }
}

output:
