Split a String by Any Number of Spaces

How to split a String by space

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.

split string by arbitrary number of white spaces

Just use my_str.split() without ' '.

More, you can also indicate how many splits to perform by specifying the second parameter:

>>> ' 1 2 3 4  '.split(None, 2)
['1', '2', '3 4  ']
>>> ' 1 2 3 4  '.split(None, 1)
['1', '2 3 4  ']

How to split a string with any whitespace chars as delimiters

Something in the lines of

myString.split("\\s+");

This groups all white spaces as a delimiter.

So if I have the string:

"Hello[space character][tab character]World"

This should yield the strings "Hello" and "World" 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 "\s", which means, you need to pass "\\s". It can get a bit confusing.

The \\s is equivalent to [ \\t\\n\\x0B\\f\\r].

Splitting string on multiple spaces in java

str.split("\\s+") would work. The + at the end of the regular-expression, would treat multiple spaces the same as a single space. It returns an array of strings (String[]) without any " " results.

Split a string with unknown number of spaces as separator in Python

If you don't pass any arguments to str.split(), it will treat runs of whitespace as a single separator:

>>> ' 1234    Q-24 2010-11-29         563   abc  a6G47er15'.split()
['1234', 'Q-24', '2010-11-29', '563', 'abc', 'a6G47er15']

Split string with variable number of spaces

You can use StringSplitOptions.RemoveEmptyEntries enumeration with String.Split method like;

The return value does not include array elements that contain an empty
string

string s = "7       300685  1235    200017  200018  200019";
var array = s.Split(new []{" "}, StringSplitOptions.RemoveEmptyEntries);
foreach (var item in array)
{
    Console.WriteLine(item);
}

Output will be;

7
300685
1235
200017
200018
200019

Here a demonstration.

Splitting a string with multiple spaces

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(" +");

Split a string by any number of spaces

Just use strsplit with \\s+ to split on:

x <- "10012      ----      ----      ----      ----       CAB    UNCH       CAB"
x
# [1] "10012      ----      ----      ----      ----       CAB    UNCH       CAB"
strsplit(x, "\\s+")[[1]]
# [1] "10012" "----"  "----"  "----"  "----"  "CAB"   "UNCH"  "CAB"  
length(.Last.value)
# [1] 8

Or, in this case, scan also works:

scan(text = x, what = "")
# Read 8 items
# [1] "10012" "----"  "----"  "----"  "----"  "CAB"   "UNCH"  "CAB"  

Split string using variable spaces

You can use regular expressions with the split function to match any number of spaces.

var lines = line.split(/\s+/);

The \s+ regular expression matches one or more spaces.

A runnable example with the strings you provided:

var lines = [

  "0.0  0.2    88 /usr/sbin/securityd",

  "47.0  0.3  7770 node",

  "1.0  2.5   585 /Applications/PhpStorm.app/Contents/MacOS/phpstorm"

];

for (var i in lines)

  console.log(lines[i].split(/\s+/));

var string = "text to split";
    string = string.split(" ");
var stringArray = new Array();
for(var i =0; i < string.length; i++){
    stringArray.push(string[i]);
    if(i != string.length-1){
        stringArray.push(" ");
    }
}
