Question 2: You have been given below code, what is the behavior expected?

package com.hadoopexam;

 

import java.time.ZoneId;

import java.time.ZonedDateTime;

import java.time.temporal.ChronoUnit;

 

public class Welcome {

public static void main(String[] args) {

ZonedDateTime startTime = ZonedDateTime.of(2016, 1, 01, 2, 0, 0, 0, ZoneId.of("UTC-4")); 

ZonedDateTime endTime = ZonedDateTime.of(2016, 1, 01, 8, 0, 0, 0, ZoneId.of("UTC-1")); 

long hrs = ChronoUnit.HOURS.between(startTime, endTime); // line n1

System.out.println("Total time difference is " + hrs + " hours");

}

}

1. Total time difference is 4 hours 

2. Total time difference is 3 hours

3. Total time difference is 2 hours 

4. An exception is thrown at line n1.

Correct Answer : 2 Exp : ZonedDateTime.of(2016, 1, 01, 2, 0, 0, 0, ZoneId.of("UTC-4")); -> UTC Time = 2+4 = 6

 ZonedDateTime.of(2016, 1, 01, 8, 0, 0, 0, ZoneId.of("UTC-1") -> UTC Time = 8+1 =9

9-6=3
