#  Overview
**`toByteArray()`** is an instance method of the `BitSet` that is used to return the `byte` array that contains all the bits in the `BitSet` object.

The `toByteArray` method is defined in the `BitSet` class. The `BitSet` class is defined in the `java.util` package. To import the `BitSet` class, use the following import statement.
```
import java.util.BitSet;
```


## Syntax

---

``` java

## Return value

The `toByteArray` method returns a `byte` array.

## Code

import java.util.Arrays;
import java.util.BitSet;

public class Main{

    public static void main(String[] args) {
        // Create empty BitSet object
        BitSet bitSet = new BitSet();

        // Set the bit at index 2
        bitSet.set(2);

        // Get the byte array of the Bitset object using the toByteArray()
        System.out.printf("%s.toByteArray() = %s" , bitSet, Arrays.toString(bitSet.toByteArray()));
    }
}

What is BitSet.toByteArray() in Java?

Converts BitSet to a byte array, containing all bits. No parameters. Returns byte array.
