import java.util.*;

public class Lautturi {

	public static void main(String[] args) {

		Byte[] bytes1 = {104, 101, 108, 108, 111, 32};
		Byte[] bytes2 = {108, 97, 117, 116, 116, 117, 114, 105, 32, 106, 97, 118, 97, 33};
		List<Byte> list = new ArrayList<Byte>(Arrays.asList(bytes1));
		list.addAll(Arrays.<Byte>asList(bytes2));

		Byte[] combined = list.toArray(new Byte[list.size()]);
		
		System.out.println(Arrays.toString(combined));
		
	}
}

output:

[104, 101, 108, 108, 111, 32, 108, 97, 117, 116, 116, 117, 114, 105, 32, 106, 97, 118, 97, 33]
