Android uses the Split function to split multiple spaces

When you frequently encounter a character-splitting string in a project, you can split it by using the Split function of the string object.
First look at the actual situation:

" key Words 1 keywords     2      keyword 3";   = Str.split ("");    for (String word:words) {      System.  out . println (Word);  }  

The results are as follows:
Keyword 1


Keyword 2


Keyword 3
But my goal is to output the following execution results:
Keyword 1
Keyword 2
Keyword 3
Look directly at the code:

" key Words 1 keywords     2      keyword 3";   = Str.split ("\\s+");    for (String word:words) {      System.  out . println (Word);  }
