if somehow you don t wanna use String split method then you can use StringTokenizer class in Java as        StringTokenizer tokens   new StringTokenizer  Hello I m your String             String   splited   new String tokens countTokens         int index   0      while tokens hasMoreTokens             splited index    tokens nextToken              index

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

I do believe that putting a regular expression in the str split parentheses should solve the issue  The Java String split   method is based upon regular expressions so what you need is   str    Hello I m your String   String   splitStr   str split    s

While the accepted answer is good  be aware that you will end up with a leading empty string if your input string starts with a white space  For example  with  String str    quot  Hello I m your String quot   String   splitStr   str split  quot   s  quot     The result will be  splitStr 0      quot  quot   splitStr 1      quot Hello quot   splitStr 2      quot I m quot   splitStr 3      quot Your quot   splitStr 4      quot String quot    So you might want to trim your string before splitting it  String str    quot  Hello I m your String quot   String   splitStr   str trim   split  quot   s  quot      edit  In addition to the trim caveat  you might want to consider the unicode non-breaking space character  U 00A0   This character prints just like a regular space in string  and often lurks in copy-pasted text from rich text editors or web pages  They are not handled by  trim   which tests for characters to remove using c  lt         s will not catch them either  Instead  you can use  p Blank  but you need to enable unicode character support as well which the regular split won t do  For example  this will work  Pattern compile  quot   p Blank  quot   UNICODE CHARACTER CLASS  split words  but it won t do the trim part  The following demonstrates the problem and provides a solution  It is far from optimal to rely on regex for this  but now that Java has 8bit   16bit byte representation  an efficient solution for this becomes quite long  public class SplitStringTest       static final Pattern TRIM UNICODE PATTERN   Pattern compile  quot    p Blank        p Blank   quot   UNICODE CHARACTER CLASS       static final Pattern SPLIT SPACE UNICODE PATTERN   Pattern compile  quot   p Blank  quot   UNICODE CHARACTER CLASS        public static String   trimSplitUnicodeBySpace String str                Matcher trimMatcher   TRIM UNICODE PATTERN matcher str           boolean ignore   trimMatcher matches       always true but must be called since it does the actual matching grouping         return SPLIT SPACE UNICODE PATTERN split trimMatcher group 1                Test     void test                 String words    quot  Hello I m u00A0your String u00A0 quot              non-breaking space here --  and there -----           String   split   words split  quot   quot            String   trimAndSplit   words trim   split  quot   quot            String   splitUnicode   SPLIT SPACE UNICODE PATTERN split words           String   trimAndSplitUnicode   trimSplitUnicodeBySpace words            System out println  quot words    quot    words    quot   quot            System out println  quot split    quot    Arrays stream split  collect Collectors joining  quot    quot       quot   quot            System out println  quot trimAndSplit    quot    Arrays stream trimAndSplit  collect Collectors joining  quot    quot       quot   quot            System out println  quot splitUnicode    quot    Arrays stream splitUnicode  collect Collectors joining  quot    quot       quot   quot            System out println  quot trimAndSplitUnicode    quot    Arrays stream trimAndSplitUnicode  collect Collectors joining  quot    quot       quot   quot             Results in  words    Hello I m  your String    split     Hello  I m  your  String    trimAndSplit   Hello  I m  your  String    splitUnicode     Hello  I m  your  String  trimAndSplitUnicode   Hello  I m  your  String

Since it s been a while since these answers were posted  here s another more current way to do what s asked   List lt String gt  output   new ArrayList lt  gt     try  Scanner sc   new Scanner inputString         while  sc hasNext    output add sc next         Now you have a list of strings  which is arguably better than an array   if you do need an array  you can do output toArray new String 0

What you have should work  If  however  the spaces provided are defaulting to    something else  You can use the whitespace regex   str    Hello I m your String   String   splited   str split    s       This will cause any number of consecutive spaces to split your string into tokens   As a side note  I m not sure  splited  is a word    I believe the state of being the victim of a split is also  split   It s one of those tricky grammar things  -  Not trying to be picky  just figured I d pass it on
