Question

String.split(String regex) splits the string around a given regular expression and returns an String array. But I am interested in the regex matches and would like them to be returned as string array instead of strings around them.
For example,
In case of trival regex like “:” it probably wouldn’t matter. But there are regexes which would match a particular date in a paragraph and I would like to get all these dates which may be different each time. I checked the jdk api but couldn’t find any such methods. Is there any method that I can make use of?. Any help would much appreciated.

Just use the Java regular expression API

Pattern pat = Pattern.compile("\\d");
Matcher mat= pat.matcher("Foo99Bar66Baz");
while(mat.find()) { 
      System.out.println(mat.group());
}
