Java regular expression to split the String

How would I split a string upon one or more spaces in between, preserving the effect of having more than one space.

e.g. when the input string is:

s = "a bc de fg "; 
spl = s.split(" ");

gives me the array 

{a, bc, de, fg}.

how do I get the same array to 1-or-more spaces in between, like

s = "a  bc  de     fg ";

TIA.

Just split the string using the below regex,

String tok[] = s.split(" +");
System.out.println(Arrays.toString(tok));

<space>+ matches one or more spaces.

You can use the + quantifier meaning "one or more".

String s = "a  bc  de     fg ";
String[] parts = s.split(" +");
System.out.println(Arrays.toString(parts)); // [a, bc, de, fg]

You may also consider using \s which matches any white space character. 

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