  • Last Updated : 29 May, 2020
Geek Week

The getInstant() method of java.time.zone.ZoneOffsetTransition class is used to get the object of instant type representing the transition between the two zone offset.

Syntax:

public Instant getInstant()

Parameter: This method does not accept any parameter.

Return Value: This method returns the object of instant type representing the transition between the two zone offset.

Below are the examples to illustrate the getInstant() method:



Example 1:




// Java program to demonstrate
// getInstant() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;
  
public class GFG {
    public static void main(String[] argv)
    {
  
        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);
  
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(8);
  
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);
  
        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);
  
        // getting the instant between two transition
        // by using getInstant() method
        Instant inst = zonetrans1.getInstant();
  
        // display the result
        System.out.println("Instant : " + inst);
    }
}
Output:
Instant : 1999-04-25T03:24:37Z

Example 2:




// Java program to demonstrate
// getInstant() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;
  
public class GFG {
    public static void main(String[] argv)
    {
  
        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);
  
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(12);
  
        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(8);
  
        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);
  
        // getting the instant between two transition
        // by using getInstant() method
        Instant inst = zonetrans1.getInstant();
  
        // display the result
        System.out.println("Instant : " + inst);
    }
}
Output:
Instant : 1999-04-25T03:24:33Z
