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:Â
Java
// Java program to demonstrate// toHours() method of TimeUnit ClassÂ
import java.util.concurrent.*;import java.util.Date;Â
class GFG {    public static void main(String args[])    {        // Get current time in milliseconds        long timeInMilliSec = new Date().getTime();Â
        // Create a TimeUnit object        TimeUnit time = TimeUnit.MILLISECONDS;Â
        // 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:Â
Java
// Java program to demonstrate// toHours() method of TimeUnit ClassÂ
import java.util.concurrent.*;import java.util.Calendar;Â
class GFG {    public static void main(String args[])    {        // Get current time in milliseconds        long timeInMilliSec = Calendar                                  .getInstance()                                  .getTimeInMillis();Â
        // Create a TimeUnit object        TimeUnit time = TimeUnit.MILLISECONDS;Â
        // 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
