TimeUnit toHours() method in Java with Examples

The toHours() method of TimeUnit Class is used to get the time represented by the TimeUnit object, as the number of Hours, since midnight UTC on the 1st January 1970. Syntax:

public long toHours(long duration)

Parameters: This method accepts a mandatory parameter duration which is the duration in milliSeconds. Return Value: This method returns the converted duration as Hours. Below program illustrate the implementation of TimeUnit toHours() method: Program 1:

Java

// Java program to demonstrate
// toHours() method of TimeUnit Class

import java.util.concurrent.*;
import java.util.Date;

class GFG {
    public static void main(String args[])
    {
        // Get current time in milliseconds
        long timeInMilliSec = new Date().getTime();

        // Create a TimeUnit object
        TimeUnit time = TimeUnit.MILLISECONDS;

        // Convert milliseconds to Hours
        // using toHours() method
        System.out.println("Time " + timeInMilliSec
                           + " milliSeconds in Hours = "
                           + time.toHours(timeInMilliSec));
    }
}

Output:

Time 1539585595812 milliSeconds in Hours = 427662

Program 2:

Java

// Java program to demonstrate
// toHours() method of TimeUnit Class

import java.util.concurrent.*;
import java.util.Calendar;

class GFG {
    public static void main(String args[])
    {
        // Get current time in milliseconds
        long timeInMilliSec = Calendar
                                  .getInstance()
                                  .getTimeInMillis();

        // Create a TimeUnit object
        TimeUnit time = TimeUnit.MILLISECONDS;

        // Convert milliseconds to Hours
        // using toHours() method
        System.out.println("Time " + timeInMilliSec
                           + " milliSeconds in Hours = "
                           + time.toHours(timeInMilliSec));
    }
}

Output:

Time 1539585598692 milliSeconds in Hours = 427662
