## Java DateTime, Calendar: Exercise-31 with Solution

Write a Java program to compute the difference between two dates (Hours, minutes, milli, seconds and nano).

Sample Solution:

Java Code:

``````import java.time.*;
import java.util.*;

public class Exercise31 {
public static void main(String[] args)
{
LocalDateTime dateTime = LocalDateTime.of(2016, 9, 16, 0, 0);
LocalDateTime dateTime2 = LocalDateTime.now();
int diffInNano = java.time.Duration.between(dateTime, dateTime2).getNano();
long diffInSeconds = java.time.Duration.between(dateTime, dateTime2).getSeconds();
long diffInMilli = java.time.Duration.between(dateTime, dateTime2).toMillis();
long diffInMinutes = java.time.Duration.between(dateTime, dateTime2).toMinutes();
long diffInHours = java.time.Duration.between(dateTime, dateTime2).toHours();
System.out.printf("\nDifference is %d Hours, %d Minutes, %d Milli, %d Seconds and %d Nano\n\n",
diffInHours, diffInMinutes, diffInMilli, diffInSeconds, diffInNano );

}
}
```
```

Sample Output:

```Difference is 6686 Hours, 401180 Minutes, 24070844780 Milli, 24070844 Seconds and 780000000 Nano
```

N.B.: The result may varry for your system date and time.
