**`ofNanos()`** is a #key# static: Methods in Java that can be called without creating an object of the class. #key# method of the `Duration` class which is used to get a `Duration` class instance representing a number of nanoseconds. The seconds and nanoseconds are extracted from the specified nanoseconds.

The `ofNanos` method is defined in the `Duration` class. The `Duration` class is defined in the `java.time` package. To import the `Duration` class, check the following import statement.
```
import java.time.Duration;
```

#   
## Syntax

```
public static Duration ofNanos(long nanos)
```

## Parameters

* **`long nanos`**: The number of nanoseconds. It can be positive or negative.

## Return value  

The method returns a `Duration` object.

# 
## Code

In the code below, we create two `Duration` class objects with a positive and negative number of nanoseconds. Then we print the objects to the console.

import java.time.Duration;

public class Main{

    public static void main(String[] args) {
        Duration positiveNonos = Duration.ofNanos(5);
        System.out.println("Positive Nanoseconds - " + positiveNonos);
        Duration negativeNonos = Duration.ofNanos(-5);
        System.out.println("Negative Nanoseconds - " + negativeNonos);
    }

}

What is Duration.ofNanos() in Java?

ofNanos() creates a Duration object from nanoseconds, handling positive or negative values.
