Given that data.txt and alldata.txt are accessible, and the code fragment:
What is required at line n1 to enable the code to overwrite alldata.txt with data.txt?
Given the code fragment:
ZonedDateTime depart = ZonedDateTime.of(2015, 1, 15, 1, 0, 0, 0, ZoneID.of("UTC-7")); ZonedDateTime arrive = ZonedDateTime.of(2015, 1, 15, 9, 0, 0, 0, ZoneID.of("UTC-5")); long hrs = ChronoUnit.HOURS.between(depart, arrive); //line n1 System.out.println("Travel time is" + hrs + "hours"); What is the result?
