Question 4
Correct Answer: A
The method truncatedTo(ChronoUnit.MINUTES) truncates the Instant object to the nearest minute. Given the loginTime of 2021-01-12T21:58:18.817Z and the logoutTime of 2021-01-12T21:58:19.880Z, both will be truncated to 2021-01-12T21:58:00Z. After truncation, loginTime and logoutTime are equal, so logoutTime.isAfter(loginTime) will return false, and the else statement will execute, printing 'Can't logout'.
