Question

What regex pattern would need I to pass to  java lang String split    to split a String into an Array of substrings using all whitespace characters         t     n   etc   as delimiters

To split a string with any Unicode whitespace  you need to use s split  quot   U   s  quot                  The   U  inline embedded flag option is the equivalent of Pattern UNICODE CHARACTER CLASS that enables  s shorthand character class to match any characters from the whitespace Unicode category  If you want to split with whitespace and keep the whitespaces in the resulting array  use s split  quot   U    lt    s      S     lt    S      s  quot    See the regex demo  See Java demo  String s    quot Hello t World u00A0   quot   System out println Arrays toString s split  quot   U   s  quot           gt   Hello  World      System out println Arrays toString s split  quot   U    lt    s      S     lt    S      s  quot           gt   Hello       World

All you need is to split using the one of the special character of Java Ragex Engine  and that is- WhiteSpace Character   d  Represents a digit   0-9   D  Represents a non-digit    0-9   s  Represents a whitespace character including    t n x0B f r   S  Represents a non-whitespace character as    s   v  Represents a vertical whitespace character as   n x0B f r x85 u2028 u2029   V  Represents a non-vertical whitespace character as    v   w  Represents a word character as  a-zA-Z 0-9   W  Represents a non-word character as    w   Here  the key point to remember is that the small leter character  s represents all types of white spaces including a single space       tab characters            or anything similar  So  if you ll try will something like this- String theString    quot Java lt a space gt  lt a tab gt Programming quot  String   allParts   theString split  quot   s  quot     You will get the desired output   Some Very Useful Links   Split   method Best Examples Regexr split-Java 11 RegularExpInfo PatternClass   Hope  this might help you the best

Something in the lines of myString split  quot   s  quot     This groups all white spaces as a delimiter  So if I have the string   quot Hello space character  tab character World quot   This should yield the strings  quot Hello quot  and  quot World quot  and omit the empty space between the  space  and the  tab   As VonC pointed out  the backslash should be escaped  because Java would first try to escape the string to a special character  and send that to be parsed  What you want  is the literal  quot  s quot   which means  you need to pass  quot   s quot   It can get a bit confusing  The   s is equivalent to     t  n  x0B  f  r
