如何在Java中拆分字符串

Question

我有一个字符串，"004-034556"我想分成两个字符串：string1="004";string2="034556";这意味着第一个字符串将包含之前的字符'-'，第二个字符串将包含之后的字符'-'。我还想检查字符串是否包含'-'在其中。如果没有，我会抛出异常。我怎样才能做到这一点？如何在Java中拆分字符串

Answer 1

// This leaves the regexes issue out of question

// But we must remember that each character in the Delimiter String is treated

// like a single delimiter        

public static String[] SplitUsingTokenizer(String subject, String delimiters) {

   StringTokenizer strTkn = new StringTokenizer(subject, delimiters);

   ArrayList<String> arrLis = new ArrayList<String>(subject.length());

   while(strTkn.hasMoreTokens())

      arrLis.add(strTkn.nextToken());

   return arrLis.toArray(new String[0]);

}
