ChronoUnit getDuration() method in Java with Examples

Last Updated : 29 Jan, 2020

The getDuration() method of ChronoUnit enum is used to return the estimated duration of this ChronoUnit in the ISO calendar system.Days vary due to daylight saving time, while months have different lengths.

Syntax:

public Duration getDuration()

Parameters: This method accepts nothing.

Return value: This method returns the estimated duration of this unit, not null.

Below programs illustrate the ChronoUnit.getDuration() method:
Program 1:

// Java program to demonstrate 
// ChronoUnit.getDuration() method 
  
import java.time.Duration; 
import java.time.temporal.ChronoUnit; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // get ChronoUnit 
        ChronoUnit chronoUnit 
            = ChronoUnit.valueOf("NANOS"); 
  
        // apply getDuration() 
        Duration getDurationAttribute 
            = chronoUnit.getDuration(); 
  
        // print 
        System.out.println( 
            "Duration Estimated :"
            + getDurationAttribute); 
    } 
} 

Output:

Duration Estimated :PT0.000000001S

Program 2:

// Java program to demonstrate 
// ChronoUnit.getDuration() method 
  
import java.time.Duration; 
import java.time.temporal.ChronoUnit; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // get ChronoUnit 
        ChronoUnit chronoUnit 
            = ChronoUnit.valueOf("DAYS"); 
  
        // apply getDuration() 
        Duration getDurationAttribute 
            = chronoUnit.getDuration(); 
  
        // print 
        System.out.println( 
            "Duration Estimated :"
            + getDurationAttribute); 
    } 
} 

Output:

Duration Estimated :PT24H
