Examice · Accepted Answer

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'.

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
