How to split a String by space (any white space)

The String splitting is a very common requirement in any programming language. In java it is very much straight forward since there is a split() method in String. Normally what we do is provide the delimiter to the split method and get the tokens into a String array.

But most of beginners don't know we can pass regular expression as a delimiter.

Here I am using a regular expression as a delimiter to split the String by any white space regardless it is a tab, space, multiple tabs or spaces.

str = "This is     the String with    different white spaces";
String[] splited = str.split("\\s+");
