StringTokenizer 與 split( ) 的差別

public static void main(String[] args) {
 String str = "1,2,,3";
 String delimiter = ",";
 StringTokenizer tokens = new StringTokenizer(str, delimiter);
 while(tokens.hasMoreTokens()) {
  System.out.println(tokens.nextToken());
 }
 System.out.println("------------------");
 String[] result = str.split(delimiter);
 for (int i = 0; i < result.length; i++) {
  System.out.println(result[i]);
 }
}

輸出結果：
