Splitting a string using Regex in Java

Question

Would anyone be able to assist me with some regex.

1 metho

String.split won't give you the desired result, which I guess would be "810", "LN", "15", since it would have to look for a token to split at and would strip that token.

Try Pattern and Matcher instead, using this regex: (\d+)|([a-zA-Z]+), which would match any sequence of numbers and letters and get distinct number/text groups (i.e. "AA810LN15QQ12345" would result in the groups "AA", "810", "LN", "15", "QQ" and "12345").

Example:

Pattern p = Pattern.compile("(\\d+)|([a-zA-Z]+)");
Matcher m = p.matcher("810LN15");
List tokens = new LinkedList();
while(m.find())
{
  String token = m.group( 1 ); //group 0 is always the entire match   
  tokens.add(token);
}
//now iterate through 'tokens' and check whether you have a number or text
