import java.util.*;

public class Lautturi {

	public static void main(String[] args) {

		String str = "hello lautturi";
		byte[] bytes = str.getBytes();
		System.out.println("Array " + bytes);
		System.out.println("Array as String" + Arrays.toString(bytes));

	}
}

output:

Array as String[104, 101, 108, 108, 111, 32, 108, 97, 117, 116, 116, 117, 114, 105]

104 is the ascii code of 'h'.
