Splitting a string with multiple spaces

Question

I want to split a string like

"first     middle  last"  

with String.split(). But when i try to split it I get

String[] array = {"first","","","","middle","","last"} 

I tried using String.isEmpty() to check for empty strings after I split them but I it doesn't work in android. Here is my code:

String s = "First  Middle Last"; String[] array = s.split(" "); for(int i=0; i<array.length; i++) {   //displays segmented strings here } 

I think there is a way to split it like this: {"first","middle","last"} but can't figure out how.

Thanks for the help!

Answer 1

Since the argument to split() is a regular expression, you can look for one or more spaces (" +") instead of just one space (" ").

String[] array = s.split(" +"); 

Answer 2

try using this s.split("\\s+");
