String.split("") puts null in the first index

So I have absolutely no idea why this is happening, hopefully someone can help me out. I'm a novice programmer, and lately I've noticed that whenever i use String.split() with "" as a delimiter, the first index will be null and the second index will contain the first element, and so on. Here's an example of some output i've been seeing:

Code :

---

public class wtf
{
	public static void main(String[] args)
	{
		String mystring = "hello";
		String[] myarray = mystring.split("");
		for(int i=0; i<myarray.length;i++)
			System.out.println(i + ": "+ myarray[i]);
	}
}

---

OUTPUT:
0:
1: h
2: e
3: l
4: l
5: o

The first element in the array looks like an empty String, not null.
I don't understand regular expressions to be able to tell you what an empty regexp String will do.

use trim before apply split function. let me know if it doe'st not solve your problem

I don't see a blank in the String that the OP posted. Do you? What would trim do with no spaces?

this is probably too late to get another response, but kB18001 I tried String.trim() first but to no avail, I get the same output
