String fullName is read from input and represents a full name. The full name has three fields separated by two occurrences of

character $\text{'}\text{'}.$ Output the second field of fullName. End with a newline.

Ex: If the input is Imani Kim Page, then the output is:

import java.util.Scanner;

public class FindMiddleField $\{$

public static void main$($String$[]$ args$)\{$

Scanner scnr $=$ new Scanner$($

System.in$)$;

String fullName;

int index$1$;

int index$2$;

fullName $=$ scnr$.$nextLine$()$;

$/*$ Your code goes here $*/$

$\}$

$\}$

How do I do this in Java. I recently learned $.$substring$($ a$,$ b$),.$indexOf$(\text{'}$a$\text{'}).$ originally this was my code:

int index$3$;

index$1=$ fullName.indexOf$(\text{'}\text{'})$;

index$2=$ fullName.lastIndexOf$(\text{'}\text{'})$;

index$3=$ fullName.substring$($index$1,$ index$2)$;

System.out.print$($index$3)$;

However, it was producing a result saying "String cannot be converted
