介绍

java.util.StringTokenizer类允许应用程序将字符串分成令牌。

  • 此类是一个遗留类，出于兼容性原因而保留，尽管在新代码中不建议使用。

  • 它的方法不区分标识符，数字和带引号的字符串。

  • 此类方法甚至无法识别和跳过注释。

3 boolean hasMoreTokens()

This method tests if there are more tokens available from this tokenizer’s string.
4 Object nextElement()

This method returns the same value as the nextToken method, except that its declared return value is Object rather than String.
5 String nextToken()

This method returns the next token from this string tokenizer.
6 String nextToken(String delim)

This method returns the next token in this string tokenizer’s string.
