Need to split a string into two parts in java

Question

I have a string which contains a contiguous chunk of digits and then a contiguous chunk of characters. I need to split them into two parts (one integer part, and one string)

Answer 1

There's always an old-fashioned way:

private String[] split(String in) {    
  int indexOfFirstChar = 0;
  for (char c : in.toCharArray()) {
    if (Character.isDigit(c)) {
      indexOfFirstChar++;
    } else {
      break;
    } 
  }    
  return new String[]{in.substring(0,indexOfFirstChar), in.substring(indexOfFirstChar)};
}

(hope it works with digit-only or char-only Strings too - can't test it here - if not, take it as a general idea)
