I want to merge two arrays, how can we do that in Java?

We can use `Stream.concat` to merge multiple arrays. Following code shows how to do that.

```java
import java.util.Arrays;
import java.util.stream.Stream;

public class JavaArrays {
	public static void main(String[] args) {
		String[] arr1 = { "a", "b", "c" };
		String[] arr2 = { "d", "e", "f" };

String[] finalArry = Stream.concat(Stream.of(arr1), Stream.of(arr2)).toArray(String[]::new);

System.out.println(Arrays.toString(finalArry));
	}
}
```

### Output:

> [a, b, c, d, e, f]
