OK, so we have to do splitting as you already got the answer I would generalize it.

If you want to split any string by spaces, delimiter(special chars).

First, remove the leading space as they create most of the issues.

str1 = "    Hello I'm your       String    ";
str2 = "    Are you serious about this question_  boy, aren't you?   ";

First remove the leading space which can be space, tab etc.

String s = str1.replaceAll("^\\s+","");//starting with whitespace one or more

Now if you want to split by space or any special char.

String[] sa = s.split("[^\\w]+");//split by any non word char

But as w contains [a-zA-Z_0-9] ,so if you want to split by underscore(_) also use

 String[] sa = s.split("[!,? ._'@]+");//for str2 after removing leading space
