Getting Instant from Current Dated Calendar Instance Example

The following example shows the usage of Java Calendar toInstant() method. We're creating an instance of a Calendar of current date using getInstance() method and printing the time of the calendar instance. Then we're print the corresponding instant using toInstant() method.

package com.tutorialspoint;

import java.util.Calendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create a calendar
      Calendar cal = Calendar.getInstance();

      // print current time
      System.out.println("Current Time:" + cal.getTime() );
    
      // print the instant
      System.out.println("Instant:" + cal.toInstant());
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Current Time:Wed Sep 28 18:31:45 IST 2022
Instant:2022-09-28T13:01:45.674Z

Getting Instant from Current Dated GregorianCalendar Instance Example

The following example shows the usage of Java Calendar toInstant() method. We're creating an instance of a Calendar of current date using GregorianCalendar() method and printing the time of the calendar instance. Then we're print the corresponding instant using toInstant() method.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create a calendar
      Calendar cal = new GregorianCalendar();

      // print current time
      System.out.println("Current Time:" + cal.getTime() );
    
      // print the instant
      System.out.println("Instant:" + cal.toInstant());
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Current Time:Wed Sep 28 18:32:21 IST 2022
Instant:2022-09-28T13:02:21.330Z

Getting Instant from Given Dated GregorianCalendar Instance Example

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create a calendar
      Calendar cal = new GregorianCalendar(2022,8,27);

      // print current time
      System.out.println("Current Time:" + cal.getTime() );
    
      // print the instant
      System.out.println("Instant:" + cal.toInstant());
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Current Time:Tue Sep 27 00:00:00 IST 2022
Instant:2022-09-26T18:30:00Z
