Java regular matches numbers and letters, and a combination of spaces

Look for a "combination of numbers and letters and spaces" in an input string, noting that the three appear at the same time, or that only numbers and letters appear without spaces.

For example, input "HG 437 djj third dufwf745, DFN^894DK Big Brother-in-law iphone 6s&&&&74854"

Output:

HG 437 DJJ

dufwf745

894dk

IPhone 6s

The following code can be implemented

1String s = "Hg 437 djj third dufwf745, DFN^894DK Big Brother-in-law iphone 6s&&&&74854";2String pattern = "([a-za-z]+\\s+[0-9]+[a-za-z0-9\\s]*|[ a-za-z]+[0-9]+[a-za-z0-9\\s]*| [0-9]+[a-za-z]+[a-za-z0-9\\s]*| [0-9]+\\s+[a-za-z]+[a-za-z0-9\\s]*] [^a-za-z0-9\\s]*];3Pattern r =Pattern.compile (Pattern);4Matcher m =R.matcher (s);5 6arraylist< String > P =NewArraylist<string>();7          while(M.find ()) {8P.add (M.group (1) );9        } Ten          One          for(String e:p) ASystem.out.println (e);
