Thread: 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:

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.

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

did you solve the problem?
