Exam 1z0-829 topic 1 question 4 discussion

truncatedTo: Returns a copy of this Instant truncated to the specified unit. Truncating the instant returns a copy of the original with fields smaller than the specified unit set to zero. The fields are calculated on the basis of using a UTC offset as seen in toString. For example, truncating with the MINUTES unit will round down to the nearest minute, setting the seconds and nanoseconds to zero.

Outputs Can't logout

A is correct

A is correct: truncatedTo() coverts the logoutTime=LoginTime => else is reached.

package q04; import java.time.Instant; import java.time.temporal.ChronoUnit; public class Q04 { public static void main(String[] args) throws InterruptedException { // Login time: 2021-01-12T21:58:18.817Z Instant loginTime = Instant.now(); Thread.sleep(1000); // Logout time: 2021-01-12T21:58:19.880Z Instant logoutTime = Instant.now(); loginTime = loginTime.truncatedTo(ChronoUnit.MINUTES); // line n1 logoutTime = logoutTime.truncatedTo(ChronoUnit.MINUTES); if (logoutTime.isAfter(loginTime)) { System.out.println("Logged out at: " + logoutTime); } else { System.out.println("Can't logout"); } } } // Result: // Can't logout
